[Anatomical correction of transposition of great vessels. Considerations on the first 50 patients operated on and analysis of the surgical choice].

After having adopted the arterial switch operation as an alternative to the Mustard operation we decided to review our results with this protocol in order to evaluate the validity of our choice. From June 1984 to Oct. 1989 a total of 50 patients underwent an arterial switch operation in our department: 36 (72%) with simple transposition of the great arteries and an essentially intact ventricular septum; 9 (18%) with transposition of the great arteries and ventricular septal defect and 5 (10%) with the Taussing-Bing anomaly. In the group with simple transposition, the age ranged between 3 and 24 days (mean 8.7 +/- 4.3 S.D.) and the weight was between 2.4 and 4.9 kg (mean: 3.46 +/- 0.42 S.D.). In the group with transposition of the great arteries and ventricular septal defect the age ranged between 7 and 690 days (mean: 194 +/- 206 S.) and the weight was between 3.1 and 9.7 kg (mean 6 +/- 2.34 S.D.). In the group with Taussig-Bing anomaly the age ranged between 9 and 216 days (means: 132 +/- 75 S.D.) and the weight was between 3.2 and 5.1 kg (mean: 4.1 +/- 0.75 S.D.). A balloon atrial septostomy was performed in 43 (86%) patients. The Lecompte manoeuvre was adopted in 49 (98%) patients. The total early mortality was 10% (5/50). In the 36 neonates with simple transposition of the great arteries, 4 (11.1%) died. Among the 14 patients with transposition of the great arteries and ventricular septal defect and Taussig-Bing anomaly there was 1 (7.1%) death. There was also 1 (2.2%) late death.(ABSTRACT TRUNCATED AT 250 WORDS)

[The heart conduction system in corrected transposition of the great vessels].

Authors collected 110 cases of transposition of great arteries between 1972 and 1989. Nine transpositions were corrected and the conduction system was studied on histological serial sections in 6 of them. Two cases of corrected transposition without septal or any other defect were described in detail, one in situs solitus, another in situs inversus. According to the literature, an anterior conduction system often tends to develop in situs solitus, and posterior conduction system in situs inversus. Two presented cases as well as other cases in situs ambiguous quoted in authors' and other papers showed that an arrangement of conduction system in corrected transposition does not depend on general visceral situs but on mutual position of atrial and ventricular septa instead.

[In utero diagnosis of situs abnormalities. A case of prenatal diagnosis of visceral situs inversus with corrected transposition of great vessels].

A case of situs inversus with discordant atrio-ventricular and ventriculo-arterial structures was diagnosed at the ultrasonography examination performed at 34 weeks gestation. This observation underscores the importance of recognizing the position of the viscerae and discordant segments of the heart, atria, ventricles and greater vessels. Overall frequency of situs inversus is estimated at 1/10,000 births. It is often associated with an inborn cardiopathy, especially corrected transposition of the greater vessels resulting from abnormal rotation of the cardiac tube. The anatomic, pathologic, embryologic, etiologic and and sonographic features of situs inversus and related anomalies of the cardiac structures is presented.

[Spiral CT and 3-dimensional reconstruction in evaluation of systemic venous obstruction after atrial switch operation for complete transposition of great vessels].

We report findings in spiral-CT from 11 adolescent or adult patients after atrial switch operation. The results demonstrate that computed tomography, particularly with the use of three-dimensional surface reconstruction, is very useful as a highly sensitive procedure for the detailed depiction of residua and sequelae after inflow correction for complete transposition. Especially systemic venous obstruction (SVO) is a well know complication following Mustard procedure for transposition of the great arteries. Demonstration of such obstruction is important, since the recognition and quantification of caval obstruction by clinical techniques is unreliable and indeed often impossible. Imaging procedures such as spiral computed tomography are important for this purpose. Advantages of spiral computed tomography, particularly with three-dimensional reconstruction, are discussed. The images were compared with findings in echocardiography and/or angiography affecting the site of operation.

[Single ventricle. New embryological-anatomical classification. I. Pathology and physiology].

The different nomenclatures which have been given to this malformation are discussed, defining the single ventrical as a single ventricular chamber without an interventricular septum and generally with two well defined atrioventricular orfices, although in some cases there is only one mitral-tricuspid ring. Twelve cases of single ventricle, proven by necropsic study, were examined. A new embriological-anatomical classification was proposed based on the location of the outflow tract (concordant or discordant in relation to the situs viscerae of which it is a part) and the troncoconal morphology (crossed great vessels, transposition of the great arteries, and truncus arteriosus), presenting some examples of these malformations. The pathological characteristics of the malformation in each of the established groups is described, as well as the physiopathology in the most frequent varieties. The defects associated with single ventricle are studied.

Retrograde catheterization of the pulmonary veins following surgical correction of transposition of the great vessels.

Prior to a Mustard repair for transposition of the great vessels, complete physiologic data of the pulmonary bed can be obtained by catheterization of the pulmonary artery with a "J" formed wire, and direct catheterization of the pulmonary veins via an atrial septal defect. Following "physiologic" repair ready access to the pulmonary veins is denied. Evaluation of the pulmonary venous pressure is of great importance, however, in differentiating pulmonary vascular disease from pulmonary hypertension secondary to patch obstruction of pulmonary venous return. This paper describes a technique of catheterization of the pulmonary veins following a Mustard repair for TGV.

Catheter management of occluded superior baffle after atrial switch procedures for transposition of great vessels.

We present successful catheter intervention in 4 patients with total occlusion of the superior baffle after an atrial switch procedure. A transseptal needle (in addition to the transhepatic route in 1 patient with known occluded femoral veins) was used to open the occluded segments and place stents. Additionally, we report the regression of multiple systemic-to-pulmonary venous fistulas that developed as a result of the occluded baffle.
