ABSTRACT: In this article, we describe two cases of anomalous connection of the left coronary artery. The first case is an infant of 4 years with an anomalous origin of the left anterior descending (LAD) artery and the diagonal branches and a circumflex artery which originated from the pulmonary artery. The second case is an adult of 50 years with the coronary artery originating from the pulmonary artery. Anomalous origin of the left coronary artery from the pulmonary artery is an uncommon congenital cardiac anomaly with an incidence of 0.25% among all congenital heart defects (Parale and Pawar [2006], J Assoc Physicians India 54:397-399). The originality of this communication consists in the use of a multislice CT scanner as a support for the angiography. The result is an original image with three dimensional details; in the case of the infant, it was determinant in the choice of the surgical approach.

ABSTRACT: Transposition of the great arteries with intact ventricular septum and aortopulmonary window is an extremely rare anatomic combination, having been reported just twice previously. Other authors performed a physiologic repair, because the combination was considered unsuitable for an anatomic repair. We describe the case of a 26-day-old baby with such anatomy who was successfully treated with an arterial switch operation. A 4 mm fenestration at atrial level was made for a smoother postoperative course.

ABSTRACT: A surgically treated case of absent pulmonary valve syndrome associated with type B interrupted aortic arch is presented. The presence of a restrictive ductus arteriosus promoted the development of a collateral circulation between ascending and descending thoracic aorta, allowing the child to remain clinically stable after birth.

ABSTRACT: Early surgical repair of postinfarction ventricular septal defect has improved early mortality rate. Mortality remains high in patients presenting within 1 week of infarction, or when rupture has occurred in the inferior part of the septum.
We describe a surgical technique for repair of postinfarction ventricular septal defect that involves no infarctectomy: continuous suturing of a bovine pericardial patch to healthy myocardium around the infarcted area and use of gelatin-resorcin-formol biological glue as a sealant between the patch and the interventricular septum.
We have used this technique successfully in 3 consecutive patients in whom repair was performed within 1 week of myocardial infarction. The rupture of the interventricular septum was located anteriorly in 2 patients and inferiorly in the other. They all made an uneventful recovery, and at follow-up there was no evidence of residual shunt.
This technique can be a useful adjunct to the surgical management of this difficult group of patients.

ABSTRACT: An 11-month-old child underwent unifocalization of the major aortopulmonary collateral arteries, but did not tolerate occlusion of both vessels simultaneously. Using a Y-shaped homograft tube, we translocated the vessels sequentially and avoided severe hypoxemia.

ABSTRACT: Aortic arch obstruction is a commonly associated problem in the Taussig-Bing anomaly. Between 1983 and 1995, 28 consecutive patients with Taussig-Bing anomaly underwent arterial switch operation with baffling of the left ventricle to neoaorta. Group A: 11/28 had associated aortic arch obstruction. Group B: 17/28 had isolated Taussig-Bing anomaly. We assessed whether the coexistence of subpulmonary ventricular septal defect and aortic arch obstruction pose an incremental risk factor.
Group A: Mean age and weight were 1.4+/-1.3 months and 3.5+/-0.4 kg. The aortic arch obstruction included: hypoplasia (5/11), interruption (4/11) and discrete coarctation (2/11). Seven patients had a one-stage correction, and four had initial arch repair followed by arterial switch operation. There were no hospital deaths (CL 0-28%). Over a follow-up of 638 patient-months (mean 64+/-39), there have been no late deaths, and all patients are in New York Heart Association class 1. There have been three cases of recurrent aortic arch obstruction (two requiring reoperation, and one requiring balloon dilation). One patient has been reoperated upon for right ventricular outflow tract obstruction. The actuarial survival and freedom from reoperation rates at 6 years were 100% (CL = 66-100%) and 72.9% (CL=38-92%) respectively. Group B: Mean age and weight were 5.9+/-8.4 months and 5+/-2.1 kg. All patients had a one-stage operation. There were two early deaths (11.8%, CL = 1-36%) and one late death over a follow-up of 678 patient-months (mean 52+/-31). All survivors are in New York Heart Association class 1 and there have been no reoperations. The actuarial survival and freedom from reoperation rates at 6 years were 81% (CL = 56-93%) and 100% (CL = 76-100%) respectively.
1. Aortic arch obstruction has not adversely affected early or late survival (P>.05) or late functional class. 2. Patients with Taussig-Bing anomaly and aortic arch obstruction may have a higher reoperation rate than those with normal arch anatomy. 3. Taussing-Bing anomaly, with or without aortic arch obstruction, can be repaired with arterial switch operation during the neonatal period with good outcome.

ABSTRACT: The surgical treatment of the CoAo plus Hypoplastic Aortic Arch is debated. The point is whether to treat or not the associated tubular hypoplasia performing an extended Resection and "End to End" Anastomosis (ERETE) or a subclavian flap angioplasty (Waldhausen). According to some report in the literature we called an arch hypoplastic if its diameter in the first or second portion was less than the patient body weight plus 1. Between January 1988 and December 1992 in our Institution 38 patients less than 3 months underwent aortic coarctation repair. In 14 cases we were able to consider the aortic arch as hypoplastic. These patients were aged between 3 days and 45 days (median 15 days), the body weight was between 2.6 and 3.9 kgs (median 3.2 kgs). 6 patients had CoAo as isolated lesion, in 3 cases there was Ventricular Septal Defect (VSD) associated. In 5 patients major intracardiac anomalies were associated (1 DORV, 1 TGA, 2 SV, 1 SV+Arterio-Ventricular discordance). In 7 cases in order to treat the arch an ERETE was performed. The other 7 patients had a Waldhausen procedure. In 5 cases a Pulmonary Artery Banding (PAB) was associated, in 1 case a palliative arterial switch operation. The hospital death was 43% (3 patients) in the ERETE group, and 28% (2 patients) in the Waldhausen group. The echocardiography and or angiography performed during the follow-up period showed a nice growth of the arch in both groups. Although from our present data it's impossible to get definitive conclusions, the ERETE doesn't give better result in terms of hospital death and long term aortic arch growth.(ABSTRACT TRUNCATED AT 250 WORDS)
