[Single left coronary artery with a fistula to the right ventricle: report of a case with successful closure]

Abstract

A 4-year-old boy of single left coronary artery associated with a fistula to the right ventricle was reported. Cardiac catheterization and selective coronary angiography revealed single left coronary artery with a fistula to the right ventricle. At operation, a single coronary artery arising from the left aortic sinus was present. A dilated and tortuous left circumflex branch passed to the right and anterior . This vessel terminated into the outflow tract of the right ventricle. The dilated vessel was doubly ligated at just distal portion of a acute marginal branch. The fistula to the right ventricle was directly sutured from arteriotomy. Then three small branches from the anterior descending artery terminating into the terminal portion of the dilated vessel were found and these were ligated respectively. After repair of arteriotomy, the remainder of the dilated and tortuous vessel was wrapped with a Dacron mesh for reinforcement. Postoperative course was uneventful and there were no complications.
