Echocardiographically all valve regurgitation, stenosis, left ventricular function, left/right atrial volume, and pulmonary artery pressure were obtained. Coronary sinus was assessed as a sonolucency in the posterior atrioventricular groove.RESULTS: Strong positive correlation was present between CS measurements and mitral mean gradient, mitral and tricuspid regurgitation grade, tricuspid stenosis gradient, pulmonary artery systolic pressure, left and right atrial volume, and New York Heart Association class. A statistically negative correlation was present between CS measurements and mitral valve area and ejection fraction. Only the mitral valve area, tricuspid regurgitation grade, and the right atrial volume were predictors of body surface area adjusted mean CS dilatation.CONCLUSION: In this preliminary study, we showed that echocardiographic assessment of dilated CS may provide useful additional information in predicting the severity of mitral/tricuspid RVD. Findings of this study needs to be confirmed in further studies.
