Aortic Valve Stenosis Clinical Trial
Official title:
Safety and Efficacy of Emergent Transcatheter Aortic Valve Implantation (TAVI) in Patients With Severe Aortic Valve Stenosis (AS): a Single-center, Prospective, Observational Cohort Study.
This is a single-centre, prospective, observational cohort study focusing on of patients suffering severe aortic valve stenosis (AS) undergoing emergent transcatheter aortic valve implantation (TAVI). AS patients undergoing emergent TAVI always have complicated clinical situations. Therefore, the aims of the study are to collect the incidence and outcomes of emergent TAVI in patients with severe symptomatic AS, to assess the safety and effectiveness of emergency TAVI system for severe AS, and to describe a more practical evidence of emergency TAVI system in severe AS patients.
