Surgical correction of sinus of Valsalva fistulas.

Four patients with fistula of the sinus of Val-salva have been treated surgically since 1966. One of them—a woman—had a right coronary sinus aneurysm with fistula to the right atrium. The other 3 patients—all men—had fistulas without accompanying aneurysms, two from the right coronary sinus to the right ventricle, and one from the non-coronary sinus to the right ventricle. One of the fistulas was of traumatic origin. The diagnosis was established by cardiac catheterization and aorto-graphy in 3 cases, and in 1 patient operated on for aortic insufficiency on vital indication, the fistula was observed intra-operatively. Cardio-pulmonary bypass was used in all patients. Three patients are well; one died of septicaemia 2 weeks after the operation.
