No doubt about it, heart valve replacement (or repair) is scary stuff.
If you’re an active person, it may come as even more of a shock.
You might be asking yourself, “how could this happen to me?”
You just want this nightmare behind you so you can get your life back to normal.
Common questions I hear from heart clients are:
- Can I exercise after heart valve replacement or repair?
- How hard can I exercise?
- When can I get back to running after a mitral valve repair?
- Can I lift weights after an aortic valve replacement?
The short answer to these questions is a resounding YES!
In fact, exercise is highly recommended after heart valve surgery, but you DO need to bear in mind some precautions and safety guidelines to reduce your risk of post-operative complications.
If you’ve had a previous myocardial infarction (heart attack), bypass surgery, or angioplasty with a stent then you may need to tailor your approach with your cardiologist.
Therefore the purpose of this article is to:
- Give you a brief overview of valvular disease;
- Discuss the main heart valve surgical procedures (Skip directly to this part);
- Provide guidelines for the immediate post-operative recovery period (Skip directly to this part); and
- Discuss key exercise recommendations for valve surgery patients (Skip directly to this part)
1) Overview: What is heart valve disease?
The normal heart
First, you have to understand that the heart is a pump.
There are two upper chambers called atria and two lower chambers called ventricles.
In between the atria and ventricles are one-way valves which allow blood to pass from the atria on top down to the ventricles at the bottom of the heart.
The mitral valve regulates blood flow from the left atrium to the left ventricle and the tricuspid valve regulates blood flow from the right atrium to the right ventricle.
The two valves that regulate the passage of blood away from the heart are called the pulmonic valve (to the lungs) and the aortic valve (to the rest of the body).
Normal valves close tightly to prevent blood flow from passing backwards through the heart.
The image below shows the normal anatomy of the heart valves.
Types of heart valve disease
- Valvular stenosis – in valvular stenosis, your heart valves become stuck together or stiffened from calcification. In this case, the heart has to work harder to pump blood through it. Over time, this can contribute to heart failure where the ticker wears out from the increased pressures.
- Valvular insufficiency – in this case, your heart valves become leaky and can allow blood to “regurgitate” backwards. This means your heart has to work harder to maintain a normal blood flow out to your body.
Causes of heart valve disease
There are a number of reasons why heart valves become insufficient or fail altogether including:
- Congenital defects – “congenital” is a fancy way of saying you were born with a valve abnormality.
- Disease or illness – two common causes of valve disease are rheumatic fever and bacterial or viral endocarditis. The latter is frequently attributed to dental procedures where bacteria from the mouth enter the blood stream and colonise the area around the valve.
- Unknown causes – in some cases, there is no identifiable cause for the valve problem.
No matter what the cause of your disease, there are a number of common symptoms which are associated with bad valves:
- Shortness of breath – if your heart is unable to pump sufficient blood to your body and lungs, then shortness of breath, fatigue, weakness, or an inability to keep up with your usual activities are logical outcomes.
- Lightheadedness – your heart’s inability to pump sufficient oxygenated blood to the brain might make you feel a bit woozy and even cause you to faint.
- Swelling – fluid accumulation around your lower extremities may occur due to the heart’s inability to adequately circulate blood not just to the body but also back up to itself.
- Chest pain or arrhythmia – in some cases, people complain of chest discomfort or may feel palpitations in their chest.
2) Common surgical procedures
So you’ve been to your cardiologist and it’s confirmed you need surgery to either repair or replace your leaky valve.
You will receive either a tissue or mechanical prosthetic heart valve depending on a number of factors including your particular condition, age, or ability or willingness to take blood-thinning medications the rest of your life.
Aortic and mitral valve surgeries are more common likely due to greater pressures found on the left side of the heart.
And it doesn’t discriminate, as even well known celebrities like Arnold Schwarzenegger and Barbara Walters have both had aortic valve replacement surgery.
Tricuspid and pulmonic valve surgery does occur but is comparatively less common.
The decision to repair or replace your valve will depend on your particular condition.
Most cardiothoracic surgeons prefer to repair the native valve (your own valve) if feasible since there is less risk of rejection.
The St Jude Medical has a short and informative article on surgery options.
Heart valve surgery video
The following short video shows a 3D animated video of aortic valve replacement surgery.
3) Post-operative activity guidelines
These guidelines refer to what I’ll phrase as “physical activity.”
I differentiate this from “exercise” because, in the post-operative phase, it’s just about getting up on your feet, puttering around, and putting some gravitational load on your body (not on flogging yourself back to health in a gym).
Remember the effect of heart valve surgery on your body is something like a controlled car wreck. It is a trauma on your body and you DO need to rest.
Give yourself permission to be human during the inpatient recovery phase which generally tends to last between four to seven days.
Full recovery from the surgery can last six to eight weeks.
You’ll probably spend a couple days in the intensive care unit for the first day or two after your surgery.
The team will diligently monitor your heart rate and rhythm, blood pressure, oxygen saturation, temperature, blood biomarkers, etc.
Once you’ve been cleared to leave the ICU, you’ll end up in one of the wards where they’ll get you up walking around the nurses’ station a few times a day.
Aside from getting your rest, one of the most important things you can do at this stage is early mobilisation.
It will help you shake off the effects of the surgery and bed rest and help you get back to feeling normal again.
If your hospital has on-site exercise physiologists or physiotherapists, have them work with you to get you moving around safely, even if you don’t feel like it!
Sternal incision site
Your chest incision is going to be sore and sensitive at this point.
Once cleared by your doctor, you should start doing some stretches and mobilisation of the shoulder girdle.
This will help promote range of motion and minimise stiffness around the neck, shoulders, chest, and back.
Also remember to be VERY diligent about keeping your sternal incision site clean.
Speak to your medical management team about their wound care procedures.
Failure to keep it clean can result in infection and another unexpected stay in the hospital.
Early activity program after discharge from hospital
Four to seven days have passed and you’ve finally been discharged from the hospital. Now what?
At this point, you’re now in the in-between stage between in-patient recovery and your regular exercise (i.e., the gym, running, sport).
During the immediate post-discharge phase, you MUST remember that even if you’re starting to feel better, there IS still healing happening on the inside.
The table below provides a graduated activity program to help you transition towards the exercise phase.
The overarching theme is that you do more frequent exercise bouts each day but for very short as-tolerated intervals.
Each week, you challenge yourself by adding about five to ten minutes to each activity bout but reducing the number of times per day you do them.
Your goal should be to graduate up to longer and longer continuous exercise bouts for fewer times per day (i.e, 1-2 bouts).
|Week||Min||Times x day|
4) Heart valve surgery exercise guidelines
First and foremost, get your cardiologist’s clearance before you get back to the gym or your regular workouts.
Everyone’s case is different, so you need some assurance that you are medically stable before you start your quest for Olympic gold!
If you’re an athlete that had to go under the knife, then I can appreciate you want to get back to your training schedule.
In this case, I would suggest asking your cardiologist to do a maximal treadmill stress test.
If everything looks stable (i.e., no rhythm abnormalities, shortness of breath, or other complications), then you’ll likely be safe to get back to your routine.
Frequency – how many times per week can I exercise?
Coming off your graduated activity program I mentioned above, you should be able to do some exercise most days of the week.
I would suggest a minimum of three (3) days per week but ideally five (5) or more.
Listen to your body and remember to ease yourself back into it.
Heart valve surgery is hard on the body and you won’t be leaping tall buildings in a single bound overnight.
Intensity – how hard can I exercise?
When I work with clients, my aim is to figure out what their current exercise tolerance is.
I will put them on a treadmill and ask “if you were walking through your neighbourhood on a flat surface, how fast would you be walking?”
We then do some experimentation to find out what that speed is.
Once the initial habitual speed is established, say 4 kph (or 2.5 mph), then the goal is to match or slightly improve upon that intensity with each session.
So if you feel tired, try to match it. If you’re feeling particularly well, then try to bump up the speed by 0.2 to 0.3 kmh (0.1 to 0.2 mph).
I reference a treadmill in the example above, but you can apply the same concept to a bike, rower, elliptical trainer, or any other piece of equipment.
I’m not necessarily a massive fan of exercise equipment per se, but it is valuable in a rehab context because it allows you to QUANTIFY your progress.
If you don’t have any exercise equipment, then you can still get out and do the same thing by walking around your neighbourhood.
You can monitor your exercise intensity by heart rate or the talk test or rating of perceived exertion discussed below.
If you have a hard time finding your pulse, get yourself a heart rate monitor or a Fitbit (which also tracks your non-exercise movement habits).
Medications like beta-blockers will blunt your heart rate response to exercise so the use of a heart rate monitor might not help you gauge your true intensity.
In this case, you can rely on what’s known as the “talk test.”
The aim is to be able to have a conversation with the person next to you while exercising.
You can huff and puff a little bit, but if you’re huffing and puffing and can no longer speak, then the intensity is probably too much.
Rating of perceived exertion
The Borg rating of perceived exertion (RPE) 6 to 20 point scale is also quite helpful if you’re on beta-blockers (as in the talk test example above).
Counterintuitive as it may sound, a 6 to 20 scale is meant to correspond to a heart rate range of 60 to 200 (i.e., just add a zero).
So at rest, most people have a resting heart rate of around 60 beats per minute.
When you’re really pushing yourself, your heart rate would be up around 160 to 200.
The RPE scale requires a bit of a learning curve.
It trains you be become self-conscious of your subjective effort and more in-tune with your body (something a lot of people lose throughout their lifetimes).
If you’re participating in a cardiac rehab program, ask the staff to teach you the ins and outs of this scale.
Duration – how long can I exercise?
As with frequency and intensity, you need to ease into it.
Depending on how well you felt during your graduated activity program (discussed above in section 3), you can just continue on from where you left off.
Pay attention to how you feel the following day. A little bit of fatigue the following day is a good thing since it lets you know you pushed yourself.
But if you feel shattered and can barely get out of bed, then you probably went a little too long.
Gradually increase and adjust your duration by 5 to 10 minutes (as tolerated).
Types – what type of aerobic exercise is best?
There is no special or preferred aerobic exercise for heart valve surgery, but to answer this, I refer to a question I pose to my audiences during seminars: “what’s the best exercise in the world?”
Answer: “the one that you enjoy and will stick with!”
Whether you like to run, cycle, or swim doesn’t really matter.
All will challenge your heart and body to become more fit and efficient at delivering oxygen and nutrients to where they’re needed most (exercising muscles!).
From a recovery standpoint, try and do aerobic exercises that incorporate the large muscles of your body like your legs and hips.
Compound movements like these will give you more exercise “bang for the buck” and will put more stress on your body to improve as compared to movements which only work the smaller muscles of the upper body.
Aerobic exercise cautions
Make sure to give yourself a 5 to 10 minute warm up and cool down phase before and after each session (particularly if you live in an extremely hot or cold environment).
Blood thinning medications are frequently prescribed after heart valve surgery to reduce the risk of blood clots (which can lead to heart attack or stroke).
If you feel a bit wobbly on your feet after surgery, try to avoid movements which increase the likelihood of falling. If you bang your head, you are at increased risk of internal bleeding.
Following on from above, beware of environmental stressors like extreme heat, cold, or strong head winds.
All these can make exercise a LOT harder and really knock the stuffing out of you.
Remember that even if you feel great, there is still healing happening on the inside.
Surgery is a trauma on the heart and the body so be nice to yourself and try not to overdo it with too much exercise too soon.
Your sternum might take up to a year to heal and get its strength back.
Signs and symptoms
Watch out for any out of the ordinary signs and symptoms.
Seek immediate medical attention if you experience chest pain, dizziness, light-headedness, shortness of breath or difficulty breathing, swelling in the ankles, extreme redness and oozing pus from your incision site, or anything else that is just doesn’t quite look right.
Early treatment can catch complications and stop them in their tracks.
Weight training (resistance exercise)
You should speak with your cardiologist or surgeon to find out if weight training is right for you and to get final clearance.
Lifting weights, particularly heavy weights, can cause a sharp spike in your blood pressure which, depending on your individual condition, may or may not be safe.
Provided there are no surgical complications or limitations in your particular condition, then you should be able to ease back into weight training.
Frequency – how many days per week can I lift weight?
Don’t try to be superman (or superwoman) after valve surgery. Start off with two to three times per week and gradually increase as tolerated.
If doing regular aerobic exercise, then remember the accumulated effect of aerobic and weight training might leave you drained.
Try to experiment to see how you can fit them together into a training regimen.
Intensity – how much weight can I lift and how hard?
If you’re just getting back into the weight room, start off with light weights and gradually progress from there.
Sets and reps will also need to be adjusted as tolerated.
Start with 4 or 5 kg (10 lb) or less during the first four to six weeks of recovery.
For example, you might use light dumbbells for your upper body exercises and maybe just body weight for squats and lunges.
Monitor for extreme soreness and adjust the weights up or down by 1-2% as tolerated.
Sternum and weight lifting
One of the main concerns most people have is whether or not the sternum can handle it.
In this case, there is an element of common sense. The sternum can take a year before it’s quite strong and ready to withstand heavy resistance placed on it (i.e., bench press).
In the immediate post-op phase, you can probably get away with lower weights and intensities and
Use light resistance in the beginning. It is far better to use light weights and learn proper form up front than start off with heavy weights and sloppy form.
Duration – how long can I lift weights?
Start off with shorter weight sessions of approximately 20 minutes and gradually progress as tolerated.
Long, drawn-out sessions can leave you exhausted and less likely to be compliant with your regimen.
And, as I mentioned above, if you’re doing aerobic training, then you’re going to have to fit it all into your schedule.
There are no shortage of weight training options on the market: circuit training, Cross-Fit, high intensity interval training (HIIT), free weights, machines, body weight training using the TRX.
How do you know which one is right for you after surgery?
If you’re still in the early phases of recovery, err on the side of caution and do lighter weights and more reps.
As you get stronger (and with your doc’s approval), you can graduate to the more intense workouts.
Weight training cautions
Weight training requires proper form and breathing technique to help minimise sharp spikes in heart rate and blood pressure.
Remember to exhale on the exertion and avoid excessive breath holding and straining.
I would suggest working with a clinical exercise physiologist or trainer with experience working with cardiac clients.
As with aerobic training, you might be prescribed blood thinning medications to reduce your risk of blood clots.
You will need to be extra careful if there is any risk of your being hit by weights or someone else since these meds can increase your risk of internal bleeding.
Take home message
You can exercise safely and effectively after heart valve surgery provided you are medically-stable and have received full clearance from your doctor.
With proper precautions and a slow and gradual approach, you will be able to work yourself back to full health.
Be on the look out for any signs or symptoms that could be early warning signs for complications.
Now get back to living!!

Hello Doctor My name is Khalid Khan I am 22 years old 9 week ago My Aerotic valve Had been Replaced Now I feel Better I have Some questions in my mind Actually I like running exercise I want to Run 1mile in 7 minutes I Discuss It with My doctor But My Doctor says Jogging is better exercise Then Running What Is your openion in This Case? The second Question is That My Left Ventricle Is become dilated so is It required any medication or Not ?
Tuesday 3rd of May 2022
Hello Dr. Sukala. I know you can’t give me medical advice over the internet, but I’m hoping you can suggest some new ideas for my doctors and me to explore about the mystery we’ve been trying to solve for more than two years. Here’s the shortest version of my long saga:
- doctor heard a murmur in mid 2019
- diagnosed with severe MVR
- no symptoms…at 47 I could run as many 8-9 minute miles as I wanted and my resting HR was 49
- decided to do a repair, open procedure that was done in August 2019
- repair seemed to go great (four sets of neochords with a 32mm Edwards Lifesciences ring…I was walking ten or so miles a day four days after surgery
- I did have aflutter four weeks after surgery and was cardio-converted but that was attributed to the trauma of the surgery
- got clearance to run again six weeks after surgery…I was off all post-operative medications by this point
- I took my time running again but it quickly became clear that something was wrong. I would be short of breath almost immediately after starting and could barely run a single 12-minute mile. I tried all sorts of training approaches for months but never really improved. After I stop running totally out of breath, my HR will usually drop really quickly…as much as 40-50 bpm in the first minute after I stop running.
- stress echos and even a stress MRI all showed “normal”
- We finally found on a TEE that I still had a “eccentric jet” of MVR along with SAM…my surgeon said the bad news was I needed another surgery but I was actually happy if it would fix the problem I never had in the first place
- second surgery (Dec 2020) also seemed to go well, but my symptoms are barely better to this day. I can run maybe one 9 or 10 minute mile but I’m struggling to breathe the entire time and can barely finish it. My resting HR is now in the mid-60s and has been since the first surgery
- it was found during the second surgery that the tissue where the neochords were anchored had stretched, so my surgeon added five more sets of neochords between the original ones and anchored them into a thicker part of the muscle. He also lighted my LAA since I’d had aflutter after the first surgery.
- I think I’ve had every test known to try to diagnose this, and I’ve closely monitored all my exercise to try to figure this out.
- one strange thing I’ve noticed is that my heart rate seems very “reactive”…it would spike to 140 if I just went up one flight of stairs soon after the first surgery. I still “feel my breath” just casually walking up a flight of stairs. When I run, though, it will usually never go above 140 and is sometimes as low as 105 when I’m barely able to breathe after a tough hill mountain biking. The few times I’ve seen it go into the 160s or so, I usually feel a little better while running. I don’t get the gradual build of my HR to a steady plateau like I used to…it seems to go up and down minute-to-minute between a pretty narrow range of 110-140 bpm. Again, this is all without any medications like beta blockers, etc.
- all the TTEs and TEEs indicate the repaired valve is good
- I’ve had cardiopulmonary exercise tests showing 34.5 VO2 Max and the only abnormality noted was “abnormal ventilatory efficiency slope” so we looked into pulmonary hypertension
- I recently had a right heart catheterization with exercise that ruled out pulmonary hypertension. VO2 Max was 30.5 at the end of the protocol but my HR was only 108 at that point - I went past the protocol and had to spin double the Watts called for to get my HR up to the range where it is when I’m trying to run.
Sorry this is so long, but I wanted to give you at least the outlines of this long saga. Overall, it feels to me like my HR is not “responding to demand” quickly enough. Not sure if that’s “electrical” or “plumbing” related. I also found this article (link below) recently that seems to indicate problems like mine could be related to the actual incision in my LV for both surgeries. That might explain one of the most confusing parts of this for me - the fact that, even though the first repair failed, fixing that problem didn’t really change my exercise intolerance. If the problem was (coincidentally) related to the incision in the first surgery, that might explain the disconnect between the actual valve repair and my ability to exercise. The reality is that I was running as much as I wanted to with severe MVR before any surgeries, so maybe this isn’t directly related to the valve itself.
Please let me know if you have any other ideas for my doctors and me to explore or if you’ve ever encountered anything like this in your practice. Thanks!

Hi Olivier, Thanks for taking the time to leave a detailed comment to explain everything you've been through, and you've clearly been through a lot over the past few years. I've seen a lot of strange things in cardiac rehab but I haven't come across the exact same thing as your situation. However, as I was reading through your history, the thing that kept coming to mind was that the first surgery might have caused some degree of nerve damage related to chronotropic incompetence. In looking through the article from the link you posted, the authors explicitly mentioned that the "left atrium incision impairs cardiac sympathetic nerves and causes CI..."
I can certainly empathise with you that this must be massively frustrating because it seems the treatment left you worse off than you were in the first place. While I can't make any comment on the decision to operate, many of the cardiologists and surgeons I've worked with have said that if someone is asymptomatic, then it's sometimes a better option to just monitor over time UNTIL they become properly symptomatic and THEN consider surgical options. Though having said that, there may have been other extenuating circumstances that could have contributed to the recommendation for surgery. In any event, you'll still need to deal with what's right in front of you right here and now.
I think you drew the same conclusion that there was some sort of electrical disruption within your heart and, while it's good that all the other tests came back within normal limits, it would seem that moving forward, it might be worth having a look around for an electrophysiologist, a cardiologist who specialises specifically in cardiac rate and rhythm disorders. I'm not exactly certain what the best course of action would be at this stage but it would certainly be worth your while to get a consult with an electrophysiologist to put all the options on the table. Structurally, based on the information you've provided, your heart seems to be ok, but it's just the electrical innervation seems to have been disrupted.
I don't know if that moves you in the right direction, but I really couldn't give you much more information than that. But the more information you can get, the better at this point, especially since you are still young and quality of life is a major factor moving forward (and particularly because you're an active person).
Feel free to stop back and leave another comment later on after you've had more evaluations. The information you provide here may benefit others going through the same or similar situation.
Kind regards, Bill

Dear Dr Sukala,
I had aortic valve replacement surgery on 1 September 2021 (just under 4 weeks ago). I had an upper mini sternotomy performed with a bovine replacement valve used to replace my leaking/regurgitating aortic valve. I'm 75 and in general good health and have lived a active lifestyle and would like to resume that same level of activity as soon as possible. I plan on engaging in a regular cardiac rehab program starting in 2 weeks. Currently I'm walking twice a day in the neighborhood (roughly a mile each session/ 2 miles each day ). Using my fitbit, I'm keeping my BPM under a 100 BPM level. My question is, a lot is said about the healing of the sternum and how low long it takes to heal, but little is mentioned as to how long it takes to heal the heart itself and the precautions moving forward? I do have plans to resume lifting weights and returning to regular exercise!
Dr Bill Sukala

Hi Jim, Thanks for taking the time to leave a comment. Great question. I think the answer to your question would really depend on the specifics of the open heart surgery itself. But, aside from any sternal discomfort, on average, most people feel reasonably well and back to normal by around eight weeks after surgery. There may still be some soft tissue healing happening on the inside but most patients I've worked in cardiac rehab with tend to be able to get back to doing most things without any worries by that 2-month mark. Ultimately, you'd have to speak with your surgeon and ask what an expected time frame is for full healing in your case.
On a positive note, I'm very happy to see that you're going to start in a cardiac rehab program. It looks like you're an active person so you'll likely benefit from it to get fine tuned to your body post-surgery to ensure that you're progressing as safely as possible.
Regarding weight lifting, if your cardiologist deems you stable and low risk, I don't think you should have any issues doing resistance training (notwithstanding extremely heavy powerlifting or other things that might warrant special consideration).
You're on the right track and taking all the correct precautions. From here, it's just a matter of time until you're feeling like your old self, or possibly even better now that you have that new valve working for you! Hope this helps.
Kind regards, Bill

If you have a mechanical valve can you use the legxercise
Monday 8th of March 2021
I am 67 y female. My dr. Referred me to a cardiologist because I was short of breath 2 times in the past 6 months. I feel fine and walk 5 days a week and previously swam 25 laps 5 days per week. I have just had tee and r and l catheterization. The results show a severely leaking aortic valve and a moderate/severe leaking mitral valve. I don't feel bad and my fear is if I have surgery that I will never get back to how good I feel now. What are the risks if I choose not to have surgery?
Sunday 11th of April 2021
@Jean LaPietra, Get your surgery done if your cardiologist recommends it. There is a test that gives numbers that tell when is the best time. I had my mitral valve repaired at Cleveland Clinic in Ohio in 2011. Fatigue is what triggered my attempt to research this. The procedures that are done now are extremely safe and the outcomes are 99% plus effective. Mine was done robotically.
Dr Bill Sukala
Monday 8th of March 2021
Hi Jean, Thanks for taking the time to leave a comment. I can certainly understand your concerns. While I cannot give any advice or make any recommendations either way, here are some points that would be worth discussing with your cardiologist.
1. While it's been objectively determined that your aortic valve and mitral valves are leaking, to what extent is your fitness "protecting" you and compensating for the leaky valves?
2. How much longer does the cardiologist think you can go without having the surgery? At some point, you will likely have to have the surgery, but only your cardiologist can give you a more firm answer in this case.
3. Does your cardiologist and/or surgeon think that they can repair your valves rather than a full replacement? If it's possible to repair them rather than replace them, then this might be a good option in the long-term.
4. If you DO decide on having the surgery, ask if there are any options for minimally invasive surgery INSTEAD of having the full sternal sternotomy. Have a look at this article to get a better understanding: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4191712/ or Google "minimally invasive valve surgery" and inform yourself of the options currently available.
Overall, you will probably find that, if you can have the minimally invasive heart valve surgery, then your recovery time will be much quicker and the overall stress on the body will be less. AND, if your valves are working well (either repaired or replaced), then you will most definitely feel much better (i.e., no shortness of breath etc which may get worse with your worsening valves).
Hopefully this information is helpful, but feel free to stop back and leave a comment again if need be.
Kind regards, Bill
