- Morphologic analysis of the mitral valve is essential to evaluate mitral regurgitation and causes of mitral insufficiency.
The cineangiographic left ventriculogram in right anterior oblique view of 100 Korean adults(62 male and 38 female) were analysed to determine the anatomy of the mitral valve. According to the position of the fulerum and the configuration of the fornix of left ventricle, four types of mitral valve were identified.
There was 52% type I, 12% type II, 29% type III and 7% type IV.
No significant difference in change of mean diameter between systole and diastole was noted among the 4 types of the mitral valve(23%).
Visualization of the left ventricular internal structure revealed no significant differences between the various types.
Because of the frequency in pseudoprolapse of mitral valve of the type 1 and 3, 2D echocardiographic and cineangiographic evaluation of mitral regurgitation should be carefully done in Koreans in whch those types are more frequent than Caucasians.
