Anomalous origin of the left coronary artery. A twenty-year review of surgical management.

Children with anomalous origin of the left coronary artery from the pulmonary artery are at risk for myocardial infarction and death. Surgical management of this condition in children has evolved significantly during the past 20 years. Between 1970 and 1990, a total of 20 of these patients underwent surgical intervention at two institutions.

Technical modifications for improved results in total anomalous pulmonary venous drainage.

To delineate factors that contribute to improved surgical outcome in patients with total anomalous pulmonary venous drainage, we reviewed the records of 52 consecutive patients. Venous drainage was supracardiac in 25 (48%), cardiac in 12 (23%), infracardiac in 10 (19%), and mixed in five (10%). Preoperative pulmonary venous obstruction was present in 18 patients (35%).

Pulmonary artery sling. Results of surgical repair in infancy.

Pulmonary artery sling is a rare congenital vascular anomaly in which the left pulmonary artery originates from the right pulmonary artery and encircles the right main-stem bronchus and distal trachea before entering the hilum of the left lung. This causes compression of the trachea and right main-stem bronchus, and most infants with this anomaly have severe respiratory distress within the first year of life. Between 1953 and 1990 12 infants (nine male, three female) underwent surgical repair of pulmonary artery sling.

Heart transplantation in neonates and in children.

Between May 1988 and July 1991, 28 neonates and children underwent orthotopic heart transplantation at Children's Memorial Hospital in Chicago. Indications for heart transplantation were hypoplastic left heart syndrome (10), dilated cardiomyopathy (13), aortic stenosis with endocardial fibroelastosis (1), complex D-transposition of the great arteries after Senning repair (1), L-transposition of the great arteries with single ventricle after shunt (1), cor biloculare, pulmonary atresia, and situs inversus after Fontan (1), and chronic rejection after heart transplantation for hypoplastic left heart syndrome (1). The age at time of transplantation ranged from 2 days to 17 years (mean, 5.

Ventricular septal defect with tricuspid pouch with and without transposition. Anatomic and surgical considerations.

In a 10-year review, patients operated on for ventricular septal defect and tricuspid valve pouch were divided into two groups, because the effect of the tricuspid valve pouch is influenced by which ventricle has the higher pressure. Group I comprised patients with ventricular septal defect without transposition of the great arteries and group II, ventricular septal defect with transposition. In 72 of 392 group I patients, the septal tricuspid valve leaflet was incised to expose the edges of the hidden ventricular septal defect to accomplish proper anatomic repair.
