The Role of Mechanical Circulatory Support in Patients With Severe Left Ventricular Impairment Treated With Transcatheter Aortic Valve Implantation and Percutaneous Coronary Intervention

Abstract

Transcatheter aortic valve implantation (TAVI) has become an established treatment for patients with severe aortic stenosis (AS) in an ever-growing patient population. It is not uncommon for patients who are undergoing TAVI to have technically difficult anatomy, simultaneous severe left ventricular (LV) impairment and/or extensive coronary artery disease. In this case series we present examples where the use of mechanical circulatory support (MCS) facilitated a safe aortic and coronary intervention in extremely complex patients who would have otherwise carried prohibitive procedural risk.
