OBJECTIVES: In line with our institutional no exclusion policy we accept patients with very poor left ventricular performance and cardiogenic shock for transcatheter aortic valve implantation (TAVI). The purpose of our study was to analyze outcome in these patients and to identify what happens to the left ventricular function after TAVI in patients with failing ventricles. METHODS: Between April 2008 and August 2013, 730 patients underwent transapical TAVI at our institution. The study group consisted of all 104 patients who presented with severely depressed left ventricular function, defined as left ventricular ejection fraction (LVEF) ≤ 30%. Based on the Society of Thoracic Surgeons predicted risk of mortality, the arithmetic risk for surgery in the study cohort was 23% ± 19% (2%-90%), and 23 patients (22%) were in cardiogenic shock. RESULTS: Excluding patients in cardiogenic shock, the survival rates in the study group at 1, 2, and 4 years were 81% ± 5%, 65% ± 6%, and 45% ± 8%, respectively. Patients in cardiogenic shock showed significantly worse outcome (P = .048). Improvement in LVEF of 50% or more was found in 74 patients (71%) and 100% or more improvement in 45 patients (43%). Early improvement in LVEF was significantly (P = .049) greater in patients with preoperative values of LVEF ≤ 20%. CONCLUSIONS: In the majority of patients with failing ventricles, left ventricular function is quickly restored after TAVI and elimination of aortic stenosis. Without the additional trauma of cardioplegic arrest, TAVI is the potentially superior treatment option in patients with poor and very poor left ventricular performance.
