The association of transposition of the great arteries (TGA) and total anomalous pulmonary venous return (TAPVR) is very rare; we report one case of this malformation with an intracardiac type of TAPVR draining into the coronary sinus. The surgical repair was performed directing the coronary sinus blood flow to the tricuspid valve. The proximity of the anatomical structures allowed an intra-atrial patch repair similar to a modified Mustard procedure. In the postoperative period the child developed low cardiac output for 2 days, requiring inotropic support and mechanical ventilation. Her recovery was otherwise uneventful. The postoperative echocardiogram showed an intact repair with perfect flow through the patch from the pulmonary veins to the right ventricle. Almost 2 years after surgery, the patient underwent cardiac catheterization that showed integrity of the surgical repair with normal pressures in all heart chambers. To our knowledge this is the first report in the medical literature of surgical treatment of this association.

Bovine pericardial (BP) grafts have been clinical use at Biocor Hospital since 1989 for replacement or repair of the ascending aorta (AsAo) and initial segment of the aortic arch (AoAr). The main advantages of BP grafts that have justified their clinical application are much easier surgical technique, perfect hemostasis and low cost. From Feb/89 to Feb/94, 88 BP grafts were implanted in the AsAo or the AoAr. There were 33 valved conduits, 47 non-valved conduits and 8 patches. The main indication for the procedure was acute dissection of the aorta, accounting for 50% of the cases. The total hospital mortality was 20.4%. Follow-up was obtained in all but two patients. Patients who survived 2 or more years postoperatively (n = 31) underwent either an echocardiographic or an angiographic study in order to access the behavior of the graft, which was perfect in all of them. The current follow-up is short and complications such as calcification may still develop. However the present study has clearly shown the superior handling and better hemostasis of BP grafts compared to the classical Dacron prosthesis.

Objectives: Recent experimental flow studies based on angiography and magnetic resonance have shown that total cavopulmonary anastomosis (TCPA) is a valid concept for surgical treatment of many congenital heart defects, but there is not agreement of the best surgical arrangement. The aim of this study is to assess the immediate results with three different techniques of TCPA.Methods: Clinical study of all TCPA performed from January 2005 to July 2008; there were 40 patients, all with previous Glenn anastomosis, with mean age of 6.4 ± 3.2 years. Three different techniques were employed: Group 1 (G1) lateral tunnel, Group 2 (G2) extracardiac conduits, Group 3 (G3) intracardiac conduit directed to the left pulmonary branch. All patients had a fenestration performed and pre-and postoperative variables were assessed.Results: G1 had 11 patients, G2 10 patients and G3 19 patients. Preoperative variables were similar in the 3 groups (P>0.05). Surgical mortality was higher in Groups 1 and 2 (9.1% and 10%) compared to Group 3 (0%) but there was no statistical significance (P=0.3841). Pleural effusion was absent in Group 3 (0%), which was statistically significant in relation to the other groups (P=0.0128). The length of hospital stay was also significantly lower in G3 (8 days) in relation to G1 (18 days) and G2 (13 days) (P=0.0164). Conclusion:Intracardiac TCPA was associated with lower postoperative morbidity and is currently our preferred technique on total cavopulmonary anastomosis. Rev Bras Cir Cardiovasc 2009; 24(4): 463-469 technique in which a olytetrafluoroethylene (PTFE) conduit is placed between the inferior vena cava and pulmonary artery, through the right atrium via the foramen ovale into the left atrium roof, where it is exteriorized and sutured to the trunk or left pulmonary artery branch. This technique allowed to reach the left pulmonary artery branch with a prosthesis smaller, with fewer curves and angles, thus minimizing the presence of inflexible material in the system. The aim of this study was to review the immediate results of patients undergoing the Fontan operation at a single institution with three models of total cavopulmonary anastomosis.

Although technical complexity remains the main cause of reoperations with this valve, experience has shown that it not only provides preservation of the left ventricular function but also promised significant increase of the ejection fraction in patients with poor left ventricular function.

Two patients who underwent surgical exclusion of the thoracic aorta for chronic dissecting aneurysms of the descending aorta died 4 and 8 years after surgery due to complications in part related to the operative technique. One patient developed pseudoaneurysm of the proximal aortic stump with fatal exsanguination through an aortapulmonary fistula. The other patient developed progressive dilatation of the remaining abdominal aorta with subsequent rupture. The surgical approach in this case was extremely difficult because of the previous exclusion procedure which determined a highly demanding reoperation. Although surgical exclusion of the thoracic aortic may be a useful technique in some situations, we must be aware of its early and late complications and, in our opinion, it should be seen only as an alternative treatment for very special patients with diseases of the descending thoracic aorta.
