Incremental value of right ventricular free-wall strain in ventricular functional mitral regurgitation: insights from a multicentre study
Ventricular functional mitral regurgitation (VFMR) is a heterogeneous condition with widely variable outcomes, yet current risk stratification relies predominantly on left ventricular (LV) indices. To evaluate the added value of right ventricular free-wall longitudinal strain (RVfwLS) beyond conventional L...
