Multiperspective Three-Dimensional Transthoracic Echocardiographic Assessment of Mitral Valve Area in Patients With Rheumatic Mitral Stenosis

Abstract

Rheumatic mitral stenosis (MS) remains common in low- and middle-income countries with significant morbidity and mortality.1,2 Echocardiographic planimetry of the mitral valve (MV) area (MVA) correlates with anatomic MVA of explanted valves better than MVA estimated by other methods.3 Three-dimensional (3D) echocardiography provides better alignment of the imaging plane at the mitral leaflet tips, yielding a more accurate planimetric measurement of the MVA.4
