TL;DR

Three-dimensional TEE-derived Vena Contracta area (3D TEE VCA) is a reliable and accurate method for assessing the severity of secondary mitral regurgitation and its use as a replacement for TEE warrants confirmation in larger multicenter studies with external validation.

Abstract

Secondary mitral regurgitation (MR) is associated with substantial cardiovascular morbidity and mortality, making accurate severity assessment essential for clinical management. Conventional 2D echocardiography has important limitations, particularly in the presence of noncircular regurgitant orifices. Three‐dimensional transesophageal echocardiography (3D‐TEE) enables direct measurement of Vena Contracta area (VCA) and may provide more accurate quantification of MR severity.
