Outcome of patients with heart failure after transcatheter aortic valve implantation.

ABSTRACT: AIMS:Patients with aortic stenosis (AS) may have concomitant heart failure (HF) that determines prognosis despite successful transcatheter aortic valve implantation (TAVI). We compared outcomes of TAVI patients with low stroke volume index (SVI) ≤35 ml/m2 body surface area in different HF classes. METHODS AND RESULTS:Patients treated by transfemoral TAVI at our center (n = 1822) were classified as 1) 'HF with preserved ejection fraction (EF)' (HFpEF, EF ≥50%), 2) 'HF with mid-range EF' (HFmrEF, EF 40-49%), or 3) 'HF with reduced EF' (HFrEF, EF <40%). Patients with SVI >35 ml/m2 served as controls. The prevalence of cardiovascular disease and symptoms increased stepwise from controls (n = 968) to patients with HFpEF (n = 591), HFmrEF (n = 97), and HFrEF (n = 166). Mortality tended to be hig
