Left ventricular-coronary sinus fistula after mitral valve replacement

One of the more rare complications after mitral valve replacement is the development of a left ventricular-coronary sinus fistula, which has been reported only twice before. In the reported cases a common feature has been multiple valve replacements. Our case was one of the late development (8 years) of a fistula in a patient who had only one previous replacement but in whom a murmur was detected 3 months after the operation.
