Extended Unroofing Procedure for Creation of a New Ostium for an Anomalous Right Coronary Artery Originating from the Left Coronary Sinus: A case report / 대한흉부외과학회지

ABSTRACT

An anomalous origin of the coronary artery with subsequent coursing between the great vessels is a rare congenital heart defect that may cause myocardial ischemia and sudden death. Several surgical techniques have been described to address this defect. An extended unroofing procedure to create an alternative ostium for the right coronary artery was successfully carried out in a patient having an anomalous origin of the right coronary artery. The newly constructed orifice was widely patent 3 months later, without any episodes of myocardial ischemia or aortic regurgitation.
