Rapid Pacing–Induced Right Ventricular Dysfunction Is Evident After Balloon-Expandable Transfemoral Aortic Valve Replacement

Transcatheter aortic valve replacement (TAVR) is an established therapy for patients with aortic stenosis [(1)][1]. Rapid pacing (RP), to ablate left ventricular (LV) ejection, stabilizes deployment and is necessary for balloon-expandable TAVR although it is less important for repositionable, self-
