Right coronary artery-to-right pulmonary artery fistula: surgical correction.

A case is described of a patient with angina pectoris in whom a diagnosis of a coronary arterial fistula arising from the right coronary artery and terminating in the right pulmonary artery had been made. The anginal pain was relieved by closure of the defect via the lumen of the pulmonary artery with the use of temporary cardiopulmonary bypass. We have been unable to find a previous description of such a condition.
