Chest Radiography in the Evaluation of Mitral Valvular Disease and it's Correlation with Echocardiography.

ABSTRACT

This study is aimed to find out various clinical, radio-graphical and echocardiographic variables to predict mitral valvular disease and their correlation with Echocardiography. This cross-sectional observational study was conducted in the Department of Radiology and Imaging, in collaboration with Department of Cardiology, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from January 2017 to December 2018. Total 50 consecutive cases enrolled in this study who was the patients of mitral valvular disease. Both chest radiograph and echocardiograph were done for each patient. There were 76% female and 26% male with a female-male ratio 3.161 with mean±SD (41.54±12.44). About 42% patients had previous history of rheumatic fever. The most common x-ray findings of heart were increased central density (90%) followed by enlargement in transverse diameter (88%), straightening of the left border (88%), widening of the carina (86%), full pulmonary conus (84%) and double contour of right border (76%). About 47(94%) patients confirmed mitral valvular heart disease on echocardiography. The prominent findings included left atrium was predominantly severely dilated (50%), severely reduced mitral valve orifice area (68%), mild mitral regurgitation (46%) and mild pulmonary hypertension (38%). And overall sensitivity, specificity, PPV, NPV and accuracy of chest radiograph in the detection of mitral valvular heart disease were 85.11%, 66.67%, 97.56%, 14.89% and 84%, respectively. These findings suggest that chest radiograph could be used as an adjunct tool with echocardiography.
