Dr. T. Munusamy, Dr. P. Kannan

Abstract :

Background: Mitral Stenosis (MS) in an obstruction to blood flow between the left atrium and left ventricle, is caused by abnormal valve function. Our aim is with use of the recent 3D echocardiography (RT3DE) to evaluate, the mitral valve and its relation to neighbouring structures in mitral stenosis, combined with Quantitative analysis software during BMV. Methods: This is a prospective, Cross-sectional hospital based study design on utilizing real time Three dimensional Transthoracic echocardiography (RT3DE) for comprehensive assessment of cardiac anatomy in patients with rheumatic mitral stenosis who underwent Balloon mitral valvotomy (BMV) Results: Our study group comprised thirty consecutive patients with rheumatic mitral valve stenosis. There were eighteen male and twelve female with mean age of 32.3 ± 8.6 years. (range 22 to 42 years). The real time 3D Echocardiogram showed well delineated commissural splitting and atrial puncture site. After Balloon mitral valvotomy, the functional capacity improved to NYHA class I and mitral valve orifice increased to 1.45 ± 0.24 cm2. Conclusion: Three dimension echocardiogram reconstruction of the mitral valve obtained by Transthoracic echocardiography during BMV is a new, non invasive imaging technique that can be accurately visualize the mechanism of successful BMV as well as some of its complications.
