Temporal Trends in Right Ventricular to  Pulmonary Artery Coupling in Patients Undergoing Transcatheter Mitral Valve-in-Valve Replacement for Degenerated Mitral Bioprostheses

Advances in transcatheter therapies have provided a safe and effective valve-in-valve option for degenerated bioprosthetic mitral valves (MVs) in patients with prohibitive surgical risk.1 However, long-standing pulmonary congestion secondary to severe bioprosthetic MV degeneration creates an adverse environment for the right ventricle (RV).1,2 Right ventricular (RV) dysfunction secondary to pressure overload is important when predicting patient outcomes post —MV intervention. Lack of RV functional improvement post–MV intervention is associated with worse outcome.
