Abstract

A 56-year-old female presented to us with rheumatic mitral stenosis with a left atrial clot. We found one coronary cameral fistula on the coronary angiography from the posterior left ventricular branch to the left ventricle. She was taken up for surgical mitral valve replacement and clot removal. A residual coronary fistula may increase the risk of infective endocarditis, especially in the presence of mechanical prosthesis. Henceforth, intra-operatively, we used the methylene blue dye injection as an easy technique to detect and safely close the coronary fistula from inside the left ventricular chamber. She recovered smoothly with a successful outcome.
