Surgical Repair of a Coronary Sinus Diverticulum not Associated with Wolff-Parkinson-White Syndrome

Diverticulum of the coronary sinus is rare. A 58-year-old man without Wolff-Parkinson-White syndrome underwent repair of a coronary sinus diverticulum accompanies by mitral regurgitation. The coronary sinus diverticulum had been identified 6 years earlier and had enlarged over time. At surgery, the neck of the diverticulum was closed, and the mitral valve replaced with a CarboMedics prosthetic valve (diameter, 29 mm). This the first case report of the surgical repair of a coronary sinus diverticulum not associated with Wolff-Parkinson-White syndrome.
