Observational Study to Collect Data of Patient Which Recieving a TAVI in TAVI Procedure

Patients with aortic valve stenosis often undergo transcatheter aortic valve implantation (TAVI) today. This biological valve can wear out or leak over time. In such cases, a second catheter-based procedure may be necessary, in which a new valve is inserted into the old one - a so-called TAVI-in-TAVI procedure. This method is considered a gentle alternative to repeat open heart surgery.

The trial will include around 300 patients from several European centres who are scheduled to undergo or have already undergone a TAVI-in-TAVI procedure with the Myval valve. Participation includes follow-up observation for a period of up to five years. Data collection will take place exclusively within the framework of regular medical care. This includes information on pre-existing conditions, the procedure, complications and subsequent hospital stays. Imaging examinations such as echocardiography or CT scans can also be centrally evaluated if they are performed routinely.
