title: [Assessment of pure isolated mitral valve insufficiency by Doppler echocardiography].
abstract: Taking 33 patients having pure MI as a material, the authors find a correlation between regurgitation fraction obtained by calculation of outputs estimated by Touch's method and angiographic values. There is a statistically significant differences (P < 0.001) between regurgitation fraction of grade I to II and grade II to III MI. The ratio mitral integral time velocity (ITV) to Aortic (ITV) is an important semi-quantitative assessment of pure MI. In fact, a ratio > 1.3 identify important degree of MI with 82% sensitivity and 93% specificity. The authors estimate that there is a correlation between the ratio of regurgitant jet surface to left atrial surface found in TEE and their degree of MI in angiography with a significant difference (P < 0.001) between the ratio of grade I to II and grade II to III MI in angiography. A ratio higher than 40% allow to identify grade III MI at minimum.
