Abstract
Background:Mitral valve prolapse is the most common anomaly of the mitral valve apparatus. Echocardiography plays a central role in the evaluation of the mitral valve. When a detailed evaluation of the mitral valve is required, transesophageal echocardiography is indicated with the advantage of better resolution and additional views. Aim:To evaluate mitral valve prolapse using trans-thoracic echocardiography. Subjects and Methods: A cross-sectional descriptive study design was done including 60 control and 60 patients with isolated mitral valve prolapse attending Suez Canal University hospital for echocardiographic evaluation, excluding children with other congenital heart diseases, rheumatic heart disease, cardiomyopathy, each participant was subjected to full medical history, general, cardiac examination, and investigations.Results: a significant difference was found between the patient and control regarding mitral leaflets long axis PML (P=0.012), mitral leaflets apical PML (P=0.000), coaptation length (P=0.000), triangle (P=0.000), chordea tendinea attached to posterior leaflet (apical parasternal view) (P=0.002),mitral regurge (P=0.000).A significant positive strong correlation was found between coaptation and mitral regurge in patients (r =0.716; P =0.001), the best critical value between mitral regurge (M1+M2) and absence of mitral regurge (Mo), to predict mitral regurge (m1+m2), the coaptation length is more than 4, the best critical value between moderate mitral regurge (M2) and mild(M1) + no regurge (Mo), to predict moderate mitral regurge (m2), coaptation length is more than 5. Conclusion: Trans-thoracic echocardiography is an effective imaging modality to evaluate mitral valve abnormalities and assess the severity and the hemodynamic consequences.
