About this trial

In this observational study, the investigators will enroll subjects who underwent TAVR or SAVR more than 3 years ago. Clinical and procedural data from the implant/surgery will be collected, alongside clinical and echocardiographic data from subsequent follow-up visits.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

None

Disqualifiers

Subjects unable to consent to participate, unless the subject has a legally authorized representative

Subjects unwilling to participate

Subject has undergone re-intervention to prosthetic aortic valve since TAVR procedure (e.g. balloon valvuloplasty, SAVR, re-do TAVR, paravalvular leak closure)

Echocardiographic evidence of prosthetic valve dysfunction within first 3 years post-TAVR (mean aortic gradient ≥20mmHg AND/OR moderate-severe transvalvular aortic regurgitation)

Trial population

This observational study will enroll subjects that underwent TAVR more than 3 years ago. TAVR. Historical controls will be selected from among patients at the same site who underwent isolated bioprosthetic SAVR more than 3 years ago
