Left ventricular–coronary sinus/right ventricular fistula late after mitral valve replacement

Development of an intracardiac fistula is a rare complication after mitral valve replacement. In the literature we have found six cases of left ventricular–coronary sinus fistula and another one of left ventricular–coronary sinus and right atrial fistula. We report the history and course of a patient in whom a left ventricular–coronary sinus and right ventricular fistula developed late after mitral valve replacement. The current study examines this type of intracardiac shunt, and presents our report on a left ventricular–coronary sinus and right ventricular fistula complication.
