TAVR for Aortic Valve Disease

Transcatheter Aortic Valve Replacement for Severe Aortic Valve Disease: Multi-center, Real-word Registry

Transcatheter aortic valve replacement (TAVR) has became an important treatment of severe aortic stenosis (AS). Several randomized clinical trials showed that TAVR was non-inferior or superior to surgical aortic valve replacement (SAVR). However, many different issues have emerged: TAVR in younger patients? valve leaflet thrombosis? transcatheter valve durability? coronary reaccess after TAVR? TAVR in bicuspid aortic valve? TAVR in aortic regurgitation? etc. Hence, a prospective, multicenter database is created to provide the real-word data for these questions.

Inclusion Criteria:

1. Clinical diagnosis of severe aortic stenosis or aortic regurgitation
2. Patients undergo transcatheter aortic valve replacement

Exclusion Criteria:

patients refuse the clinical follow-up
