Assessment of global and longitudinal right ventricular function. Schematic illustration of right ventricular ejection fraction (RVEF, a), longitudinal contribution to right ventricular ejection fraction (RVEFlong, b) and free wall longitudinal strain (FWLS, c) analysis employing meshes from the same patient derived from three-dimensional speckle-tracking transesophageal echocardiography
