The conduction system in simple, regular (D-), complete transposition with ventricular septal defect. 1976

S Bharati, and M Lev

This is a serial section study of the conduction system in 5 cases of complete (d-) transposition with ventricular septal defect (VSD) . In 3 of the cases with infracristal or intracristal VSD, the bundle lay in the posterior (inferior) wall on the left side of the defect. In the fourth case with infracristal VSD it was on the right side of this wall. In the case with a more distally situated VSD, the bundle branches skirted the anterior and distal walls of the defect. This study shows that in closure of the VSD in complete transposition, the posterior wall of the defect in some cases, and in others the anterior and distal walls of the defect are to be handled judiciously. The right side of this wall is probably safer to handle from the standpoint of block than the left side in most cases. His bundle recording during open-heart surgery may be indicated in large or unusually located VSD's to delineate the course of the conduction system and thereby to avoid atrioventricular (A-V) block.

D006327	Heart Block	Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.

D006329	Heart Conduction System	An impulse-conducting system composed of modified cardiac muscle, having the power of spontaneous rhythmicity and conduction more highly developed than the rest of the heart.

D006345	Heart Septal Defects, Ventricular	Developmental abnormalities in any portion of the VENTRICULAR SEPTUM resulting in abnormal communications between the two lower chambers of the heart. Classification of ventricular septal defects is based on location of the communication, such as perimembranous, inlet, outlet (infundibular), central muscular, marginal muscular, or apical muscular defect.

D014188	Transposition of Great Vessels	A congenital cardiovascular malformation in which the AORTA arises entirely from the RIGHT VENTRICLE, and the PULMONARY ARTERY arises from the LEFT VENTRICLE. Consequently, the pulmonary and the systemic circulations are parallel and not sequential, so that the venous return from the peripheral circulation is re-circulated by the right ventricle via aorta to the systemic circulation without being oxygenated in the lungs. This is a potentially lethal form of heart disease in newborns and infants.
