Study protocol for an internahaational prospective non-randomised trial evaluating the long-term outcomes of transcatheter aortic valve implantation versus surgical aortic valve replacement for aortic-valve stenosis in patients at risk to severe valve obstruction: the TAVISAR trial.

ABSTRACT:

Background

Aortic valve stenosis (AVS) represents the most prevalent primary valvular lesion necessitating surgical intervention or transcatheter intervention in Europe and North America. Its prevalence is increasing at a rapid rate as a consequence of the ageing population. A variety of mechanical interventions are available to determine the management of AVS; however, there is currently a paucity of robust data with which to perform a comparative analysis of the efficacy of surgical aortic valve replacement (SAVR) and that of conventional stented xenograft bioprostheses (BP) or sutureless aortic valves (SAV) and transcatheter aortic valve implantation (TAVI). The present study aims to compare the effectiveness and clinical outcomes of SAVR using BP or SAV technique and TAVI in pa
