Safety and feasibility of retrograde INOUE-BALLOON for balloon aortic valvuloplasty without rapid ventricular pacing during transcatheter aortic valve replacement.

ABSTRACT: Rapid ventricular pacing (RVP) is commonly employed during transcatheter aortic valve replacement (TAVR); however, frequent TAVR is associated with worse prognoses. The retrograde INOUE-BALLOON^® (IB) allows balloon aortic valvuloplasty (BAV) without RVP. The aim of this study was to evaluate the feasibility of retrograde IB for TAVR preparation. The study population included 178 consecutive patients (mean age, 84 ± 5 years; male, 47%) who underwent retrograde BAV before prosthetic valve replacement via the transfemoral approach. Patients were divided into a retrograde IB group without RVP (n = 74) and a conventional balloon (CB) group with RVP (n = 104). The primary endpoint was prolonged hypotension after BAV (reduced systolic pressure < 80 mmHg for over 1 min or vasopressor dr
