The study objective is to evaluate safety and effectiveness/performance of the Microport™ CardioFlow VitaFlow™ Transcatheter Aortic Valve System for the treatment of severe aortic stenosis in the real world settings.
This is a prospective, single-arm, multi-center, observational, post-market registry study. The purpose is to evaluate the safety, performance, and effectiveness of the VitaFlow™ Transcatheter Aortic Valve System in the real world settings.Patients will be seen at pre and post procedure, discharge, 30 days, 1 year and annually up to 5 years.
