The Prognosis of Baseline Mitral Regurgitation in Patients with Transcatheter Aortic Valve Implantation.

ABSTRACT: Mitral regurgitation (MR) is the most common valvular lesion in transcatheter aortic valve implantation (TAVI) recipients. This study aims to assess the long-term prognostic impact of baseline MR in TAVI patients.

Methods

Adult patients who underwent TAVI were identified in the French National Hospital Discharge Database. All-cause and cardiovascular mortality, stroke, and rehospitalization with heart failure (HF) were compared in TAVI patients with and without baseline MR and tricuspid regurgitation (TR), respectively; the associations of MR and TR with the outcomes were assessed by Cox regression.

Results

Baseline MR was identified in 8240 TAVI patients. Patients with baseline MR have higher yearly incidence of all-cause mortality (HR: 1.192, 95% confidence interval CI: 1.1
