详细描述
There is limited available information on long term TAVR valve function. 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. Up-to-date echocardiography will be performed and analyzed in a Core Lab to assess valve function yearly.
