Interruption of the aortic arch associated with patent ductus arteriosus and ventricular septal defect. Proposal of a new surgical technique for total correction.

A four-year-old girl underwent complete correction of the association of interruption of the aortic arch (Type A, Celoria and Patton's classification), patent ductus arteriosus, and ventricular septal defect. The surgical procedure consists of establishment of a continuity between the ascending and descending aortas utilizing the patent ductus arteriosus and the anterior wall of the pulmonary arterial trunk, reconstruction of the rest of pulmonary arterial trunk with pericardium, and closure of the ventricular septal defect. Though the patient expired from cerebral complications, the hemodynamic result after repair was quite satisfactory. The procedure described makes total correction of this complex anomaly feasible at one operation through a median sternotomy and seems to be a method of choice for most patients with this association of anomalies, unless there is severe narrowing of the patent ductus arteriosus.

Left ventricular function and coronary morphology with anomalous origin of the left coronary artery from the pulmonary artery.

Reconstructive surgery of the left coronary artery system was performed in two adult patients with anomalous origin of the left coronary artery from the pulmonary artery. Postoperative studies were carried out at 2 months and at 49 months. Left ventricular volume, left ventricular myocardial mass, and ejection fraction were normal postoperatively in one patient. In the second patient, the left ventricular volume was markedly reduced, but the decrease in left ventricular mass was less pronounced. Dilatation and tortuosity of the right coronary artery disappeared postoperatively in both patients. However, the dilatation and tortuosity of the left coronary artery persisted on coronary arteriogram.
