Since 1970, 7 patients varying in age between 1 month and 3 years have had successful correction of an aortopulmonary septal defect. Three of these patients had associated cardiac lesions which were repaired at the same time. Extracorporeal circulation was used in 3 patients and profound hypothermia with limited extracorporeal circulation in 4. In 5 patients the defect was closed with a Dacron patch through a transaortic approach. The advantages of this method are discussed.

Successful total repair in one stage was performed in a 3-year-old girl who had interrupted aortic arch associated with aortic septal defect and patent ductus arteriosus. Surface-induced deep hypothermia and interrupted perfusion were used. The results of postoperative catheterization and angiocardiographic studies are analyzed, and the literature and results of previous surgical attempts at correction are reviewed.

An 8 week old infant with severe heart failure from type 1 truncus arteriosus underwent successful corrective surgery employing the Rastelli procedure with use of deep hypothermia and total circulatory arrest. Postoperative hemodynamic studies showed complete closure of the septal defect, disappearance of truncal stenosis, but presence of mild porcine valve stenosis. This procedure is possible even in very small subjects and is preferable to palliative pulmonary arterial banding.

We present a new approach for anatomic correction of transposition of the great arteries. The two coronary arteries, with a piece of the aortic wall attached, are transposed to the posterior artery. The two aortic openings are closed with a patch. The aorta and pulmonary artery are transected, contraposed, ant then anastomosed. The interventricular septal defect is closed with a patch, through a right ventriculotomy approach, because the right ventricle is no longer part of the systemic circulation. Two patients, aged 3 months and 40 days weighing 4,200 and 3,700 grams, respectively, were operated upon with deep hypothermia and total circulatory arrest. There was good recovery from the operation, with normal cardiocirculatory conditions. Renal failure developed in the first patient, and she died on the third postoperative day. During this time the cardiocirculatory conditions were good. The second patient made an uneventful recovery. Hemodynamic studies 20 days after the operation showed complete correction of the malformation. Five and one-half months after the operation, he weighs 7,500 grams, and his development is very good. We believe that this operation will be reproducible by most cardiovascular septal defect and pulmonary hypertension.

We report our experience with 103 consecutive children who underwent repair of complete atrioventricular septal defect between 1971 and 1990. Ninety-one patients were less than 18 months old (mean age, 6.2 months; mean weight, 5.8 kg) and were repaired using deep hypothermia and circulatory arrest. There were 15 perioperative deaths. Twelve patients were older (mean age, 40.2 months; mean weight, 18.9 kg) and were repaired using moderate hypothermia and cardiopulmonary bypass. There were two perioperative deaths. Repairs were performed with the single-patch technique. Four younger patients required repeat repair to control residual mitral regurgitation. Two of the older children required late reoperation to replace one or both atrioventricular valves. Three younger children underwent pulmonary artery banding initially; 1 died after complete repair. Three older children underwent initial pulmonary artery banding; 2 died at definitive repair, and the survivor required pulmonary artery reconstruction, which was repeated subsequently. Since 1977 our policy has been to perform primary definitive repair whenever possible. Two patients died late from unrelated causes. At the most recent follow-up the majority of patients had no or minimal symptoms. We continue to advocate primary definitive repair whenever possible using the single-patch technique in symptomatic patients with complete atrioventricular septal defect.

Interruption of the aortic arch is practically always associated with intracardiac malformations of variable complexity, at the least, a ventricular septal defect. Surgery is usually performed in two stages: aortic repair and pulmonary artery banding after intravenous prostaglandin administration. The second stage comprises debanding and repair of the intracardiac lesions under cardiopulmonary bypass. However, in some cases, interruption of the aortic arch is associated with intracardiac lesions which necessitate correction under cardiopulmonary bypass from the onset, this was the situation in two of the three cases described by the authors: aorto-pulmonary window, a lesion which can only be corrected under circulatory arrest and deep hypothermia. One of these two children, operated in the neonatal period, did not survive: the other, operated at 6 weeks, had an excellent result. In the third case, the association of tricuspid atresia and a restrictive ventricular septal defect necessitated enlargement of the septal defect and therefore, open heart surgery under circulatory arrest; the results were favourable.

Two hundred and twenty-five consecutive patients with interventricular septal defect and associated pulmonary hypertension have undergone corrective surgery at the Christian Medical College Hospital. The mean preoperative systolic pulmonary artery pressure was 70.5 (range 31-136) mm Hg and the calculated pulmonary vascular resistance ranged from 300 to 1680 dyn/s cm-5. A paracoronary right ventriculotomy was the approach of choice. Profound hypothermia and circulatory arrest were not used, even in 12 patients weighing under 10 kg. Among the older children and young adolescents there were 27 who had a calculated pulmonary vascular resistance of over 800 dyn/s cm-1 and their mortality was 22%, which is good when compared with that of other series. It is evident that both the early and the late death rate after surgery increase with the age of the patient, especially in those with associated pulmonary hypertension. In 69 patients studied after repair recatheterisation showed no residual defect by oximetry. The fall in the pulmonary artery pressures after surgery has been striking in most patients. The late death rate was 2.5%. The surviving patients are leading normal, active lives.

This report describes an operation, successfully performed by the authors, on an aorta septal defect (A-P Window) associated with patent ductus arteriosus (PDA) and aberrant right subclavian artery (ARSA). When an A-O Window is complicated by PDA and ARSA, preoperative diagnosis is often difficult. It is often mistaken for a large PDA and ARSA. Therefore at the time of operation of a large PDA and ARSA, it is necessary tao keep artificial heart-lung machine ready so that the A-P Window can be corrected at the same operation if necessary. In this case, the aortopulmonary communication was closed directly by transpulmonary approach under profound hypothermia with extracorporeal circulation after the division of ductus arteriosus and the dissection and mobilization of the stenotic esophagus from surrounding tissues of the ARSA. The division of the ARSA was not carried out, because patient was asymptomatic. The A-P Window associated with PDA and ARSA has apparently not been reported.

Pulmonary artery pseudoaneurysm after PA banding is a rare complication and its mortality is very high. The authors successfully operated on this sort of lesion. To our knowledge, this is the first successful case in Japanese literature. The second of twins was found to be suffering asplenia, dextro cardia, TAPVC, atrioventricular septal defect, corrected TGA and PDA. On the 19th day of life, increasingly pulmonary congestion forced us to operate. We performed PDA ligation, correction of TAPVC, together with extrathoracically adjustable PA banding. 5 months following this operation, spike fever and swelling of anterior thorax were noted. PA angiography was performed, and it showed that the pulmonary artery had been cut through by the band and a pseudoaneurysm had developed. The PA banding was removed and an end-to-end anastomosis of the PA was performed using cardiopulmonary bypass and deep hypothermia with surface cooling. The diameter of the PA anastomosis was designed to be one half that of her aorta. Staphylococcus aureus was cultured from the specimen of the PA band. It was thought to have contributed to the development of this aneurysm. The post operative course was uneventful.

The goals for repairing complete atrioventricular canal (atrioventricular septal defect) are ventricular septation, atrial septation, mitral valve reconstruction, and tricuspid valve reconstruction. Complications to avoid are heart block, residual septal defects, and dysfunctional atrioventricular valves. The surgical repair of atrioventricular canal has undergone major advances over the past 40 years. Excellent short- and long-term results have been achieved with both the single-patch technique and the two-patch technique. The single-patch technique is accomplished by dividing the common valve leaflets into their respective tricuspid and mitral components, suspending them from a single patch used to close the atrial and ventricular septal defects. The two-patch technique uses a prosthetic patch for the ventricular septal defect, a pericardial patch for the atrial septal defect, and suture closure of the anterior mitral cleft. Other variables include the use of deep hypothermia and circulatory arrest, mitral cleft closure, interrupted versus continuous suturing technique, and age at operation. Perhaps more important than the applied method is that the operation be properly executed to ensure defect closure and competent valves. We review our experience in 120 patients using the two-patch technique with special reference to the technical aspects of the operation. The two-patch technique of repair with routine cleft closure as evaluated by intraoperative transesophageal echocardiography results in a low surgical mortality, a low incidence of permanent heart block, and competent atrioventricular valves.
