A Case Report of Single Left Coronary Artery with a Fistula to the Right Ventricle / 日本心臓血管外科学会雑誌

ABSTRACT

This is a case report of a rare combination of a single coronary artery and a coronary artery fistula. An 8-year-old girl was asymptomatic with a grade II continuous murmur in the third left intercostal space. Selective coronary angio-graphy revealed that a single coronary artery arising from the left aortic sinus was dilated and ended as a fistula to the outflow tract of the right ventricle. At operation, the fistula could not be exposed on the surface of the heart. On cardiopulmonary bypass, the aorta was clamped, and the fistula was closed by direct suture in the right ventricle. The postoperative course was uneventful with no complications.
