Chick embryos are frequently used as animal models when researching the developing heart. In the past, every attempt to induce complete transposition (the combination of concordant atrioventricular and discordant ventriculo-arterial connections) failed in chicks, suggesting that it might be impossible to develop a chicken model for this malformation. We demonstrate, ...
Gallego P - - 1998
A case of unusual longevity to the age of 58 years is reported for a female patient with complete transposition of the great arteries. The association with a wide atrial septal defect with intact interventricular septum may have contributed to the long survival without surgery. Factors determining intercirculatory mixing and ...
Gaudio C - - 1998
Corrected transposition of the great arteries is a rare congenital heart disease, affecting 1% of children with cardiac malformation. Patients with transposition of the great arteries and without associated cardiovascular anomalies are very infrequent and may remain undiagnosed until adult life, because they usually are asymptomatic until the fourth or ...

Intraoperative thermal coronary angiography was successfully applied in 9 patients who underwent operative correction of congenital heart defects: arterial switch operation for transposition of the great arteries (n = 5), Ross operation for valvar aortic stenosis with regurgitation (n = 3), and aortic implantation of the left coronary artery for ...
Grunwald Z - - 1997
We describe the obstetric anesthetic management of a patient with complex congenital heart anomaly consisting of transposed great arteries, double inlet left ventricle and subpulmonic stenosis. Successful management of a patient with Fontan physiology mandates a thorough understanding of the hemodynamic consequences of this procedure and the alterations during pregnancy. ...
O'Sullivan J - - 1997
In transposition of the great arteries the right lung is preferentially perfused, and this may be due to the orientation of the right pulmonary artery when the main pulmonary artery comes off in a posterior position. In this study the mean perfusion of the right lung was 61% in six ...
Santoro G - - 1997
Physiologically corrected transposition of the great arteries (cTGA), defined by discordant atrioventricular and ventriculoarterial connections, is an uncommon congenital cardiac malformation. It rarely exists without associated cardiac anomalies, the most common of which are ventricular septal defect, pulmonary outflow obstruction, tricuspid valve (systemic) deformity, and rhythm disturbances. Conversely, hypoplasia of ...
Craig S R - - 1997
No method of classifying pulmonary fissures currently exists, however, the nature of the fissure is of great importance in planning operative strategy for thoracoscopic pulmonary resection where an incomplete fissure may contribute to post-operative air leakage. In order to provide a framework for description of operative technique and to allow ...
Todd J L - - 1997
BACKGROUND: The neural crest influences the differentiation of the branchial arches, including the precursor tissue of the cardiac outflow tract and the eustachian tubes. Abnormal eustachian tubes are associated with otitis media. We hypothesized a relationship between conotruncal anomalies and eustachian tube anomalies. METHODS: We surveyed 115 nonsyndromic patients, aged ...

Männer J - - 1997
The term 'double-outlet left ventricle' (DOLV) denotes congenital heart malformations in which the aorta and the pulmonary trunk both arise entirely or predominantly above the morphologically left ventricle. In the past, the formal pathogenesis of DOLV was explained by an abnormal topogenesis of the origin of the great arteries, which ...
Emmel M - - 1997
We describe two cases of left-side pulmonary vein obstruction observed after the arterial switch operation (Jatene) for D-transposition of the great arteries. This appears to be related to left-sided pulmonary vein obstruction occurring coincidently with D-transposition of the great arteries, rather than a consequence of arterial switch operation.
Yasuura K - - 1997
A case report of difficult sternal closure is described. Chest closure following cardiac operation in critically ill patients can be a problem. Techniques have been described so that sternal closure can be delayed until the patient is hemodynamically stable and hemostasis has been achieved. However, in some instances, the sternal ...
