Surgical Repair of 115 Patients With Anomalous Aortic Origin of a Coronary Artery From a Single Institution.

Objectives: Anomalous aortic origin of a coronary artery (AAOCA) has been associated with myocardial ischemia and sudden death. The past decade has provided important insights into the natural history and typical patterns of presentation. However, there are also a number of unresolved controversies regarding the indications for surgery and the efficacy of that surgery.

Double-Switch Repair of Corrected Transposition in Association With Criss-Cross Atrial Morphology.

Corrected transposition is a relatively uncommon congenital heart defect characterized by discordance at both the atrioventricular and ventriculoarterial levels. A rare subset of patients with corrected transposition also have criss-cross atrial morphology. We report the surgical treatment of 2 patients with corrected transposition in association with criss-cross atrial morphology, emphasizing the novel atrial baffle required for this operation.

Anatomic Factors Associated With Truncal Valve Insufficiency and the Need for Truncal Valve Repair.

Purpose: Truncus arteriosus is a complex and heterogeneous form of congenital heart defect. Many of the risk factors from several decades ago, including late repair and interrupted aortic arch, have been mitigated through better understanding of the entity and improved surgical techniques. However, truncal valve dysfunction remains an important cause of morbidity and mortality.

Surgical repair of anomalous aortic origin of a coronary artery.

Objectives: Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital heart defect that has been associated with myocardial ischaemia and sudden death. There is an ongoing controversy over the indications for surgical intervention and the efficacy of that treatment compared with the natural history. The purpose of this study was to evaluate the medium-term results of surgical repair of AAOCA.

Unifocalization of major aortopulmonary collaterals in single-ventricle patients.

Background: Unifocalization of major aortopulmonary collateral arteries (MAPCAs) in pulmonary atresia with ventricular septal defect and intracardiac repair has become the standard of care. However, there are no reports addressing unifocalization of MAPCAs in single-ventricle patients. It is unknown whether their pulmonary vascular bed can be reconstructed and low enough pulmonary vascular resistance achieved to allow for superior or total cavopulmonary connections.

Homograft valved right ventricle to pulmonary artery conduit as a modification of the Norwood procedure.

Background: The use of a right ventricle to pulmonary artery (RV-PA) conduit in the Norwood procedure has been proposed to increase postoperative hemodynamic stability. A valve within the conduit should further decrease RV volume load. We report our clinical experience with this modification.
