Aortic Valve Stenosis With Insufficiency

This study aims to investigate the prevalence and characteristics of multiple and mixed valvular heart disease (MMVD), which includes combinations of stenotic or regurgitant lesions on cardiac valves. The research will be conducted as a multicenter observational study, involving several centers worldwide, and will have a one-year follow-up period (with a possible extension to 5 years). The primary aim is to determine the proportion of MMVD among patients evaluated for valvular heart disease. Secondary aims include the evaluation of the epidemiologic distribution of clinical, biological, and cardiovascular imaging characteristics at baseline, management strategies, and their impact on prognosis. The study will also evaluate clinical outcomes such as mortality, hospitalization for heart failure, and changes in echocardiographic parameters. This research aims to provide valuable insights into the diagnosis, management, and prognosis of MMVD, addressing an important knowledge gap in this area.

To collect information about the management of symptomatic severe Aortic Stenosis (AS) and Aortic Regurgitation (AR) using transcatheter aortic valve replacement (TAVI).
