Mitral annular geometry in normal and myxomatous mitral valves: three-dimensional transesophageal echocardiographic quantification.

The mitral annulus (MA) has a complex dynamic geometry that is difficult to visualize in two dimensions; hence, novel real-time three-dimensional transesophageal echocardiography (RT-3D-TEE) provides insights into its dynamic nature. The study aim was to investigate changes in MA geometry in normal subjects and to explore differences in patients with myxomatous mitral valve disease (MMVD), using 3D quantitation with RT-3D-TEE.Thirty-five...
