Assessment of mitral valve adaptation with gated cardiac computed tomography: Validation with three-dimensional echocardiography and mechanistic insight to functional mitral regurgitation
Cardiac-Gated Imaging Techniques
Mitral Valve Insufficiency
Multidetector Computed Tomography
MV size measured by CT is comparable with 3D echocardiography. MV enlargement in cardiomyopathy suggests leaflet adaptation. Patients with FMR have inadequate adaptation as reflected by decreased ratios of leaflet area and areas determined by ventricle size (annulus and closure areas). These measurements provide additional insight into the mechanism of FMR.
