Traumatic sinus of Valsalva fistula.

Two rare cases of nonpenetrating trauma-induced fistula from the right sinus of Valsalva to the right heart chambers are reported. Both were diagnosed preoperatively and operated on successfully. A transverse tear was found in the right sinus of Valsalva, just below the right coronary ostium, in both patients. The ragged inlet and a rough fistula tract were noted during operation. The tears were closed with direct sutures or with a Dacron patch. Coronary artery bypass grafting was needed in 1 patient. The results of operation were excellent.
