The life of your TAVR / TAVI valve depends on numerous factors and differs for each person. However, its functioning can be checked from time to time through regular follow-up with your doctor.

No, the valve will not be felt after placement.

First prerequisite is - patients should have critical aortic stenosis. The narrowing of the aortic valve should be critical. And as I mentioned, to give you a parameter one centimeter square of aortic valve area or less. So these are the candidates and which TAVR should be considered. The patient should be symptomatic like breathing discomfort or syncope episode, loss of consciousness or chest discomfort or a heart function is going down because of the dysfunction. So these are the subset of patients who require the aortic valve treatment.

Now we do the further ramification whether they are fit for surgical aortic valve replacement. We need to ascertain that fact. If the patient is beyond sixty-five years of age, the heart is frail, then the patient becomes a very high-risk candidate for surgical aortic valve replacement. And those are the patients where we're clear, as a guideline, that tavr is indicated and preferred over surgical AVR.

There are other factors also where they become very high risk for surgical aortic valve replacement- Like any comorbidities, the patient has a lung problem, the patient may have a liver issue or other comorbidities, the patient may have a heart dysfunction of severe gravity that itself is a high-risk factor for surgery. So all these subsets are clear indicators for tavr to be considered over and above the surgical aortic valve replacement.
