My father had his replaced two summers ago. He is 94 this year. I don't recall specific instructions other than to take it easy as a general post-op recovery from the stress of travel, busted routine, being poked and jabbed, and of course from the anesthesia....which some need a week or more to recover fully from. Some of that is just catching up on sleep if the days leading up to the procedure are anxious ones and sleep is fleeting.

The repair is actually an insertion, like an inner sleeve, that helps the existing aortic valve to function better. It's literally snapped, or sprung, into place, at which it instantly becomes a helper and the heart's ejection fraction through that valve should improve by at least 30%...normally.

There is usually a follow-up imaging to ensure the insertion is in place and oriented properly....IOW, a confirmation visit.

I don't recall any proscription about heavy lifting, going up stairs, etc....straining on the toilet. However, I was not the patient, and not present when the final instructions to my dad were either handed to him in pamphlet form or verbally imparted.

From one site I found with a quick search of the question:

"...You’ll Return to Activities Gradually
In most cases, doctors encourage walking for short periods after TAVR. Gradually, you’ll add activities and intensity over a month or so. Follow all instructions for climbing stairs, lifting things, and resting. Doing too much too fast can cause problems. Ask your doctor when it’s safe to return to daily activities, driving, work, sex, and leisure activities. It may take several weeks to months before you get back to all of your regular activities, depending on your overall health and heart health..."

Note that the above prescription gives the indication that all TAVR patients are not the same. Some have serious cardiac issues or condition that might require cardiac rehabilitation. My dad, although old at the time, was still out and about, still driving, and walked everywhere else. His heart just had a wonky aortic valve.
