Coronary sinus septal defect associated with tricuspid atresia.

Coronary sinus septal defects are unusual congenital anomalies that may assume particular clinical importance in patients undergoing a modified Fontan procedure. Two of 10 patients with tricuspid atresia who underwent a modified Fontan procedure between January, 1984, and December, 1984, were noted to have coronary sinus septal defects in the early postoperative period. A pathologic review of 159 specimens of tricuspid atresia revealed coronary sinus septal defects in four. Although infrequent, coronary sinus septal defects may permit significant persistent right-to-left interatrial shunting after a modified Fontan procedure. Ideally, preoperative recognition allows for selective direct closure or closure of the coronary sinus orifice. Alternatively, routine baffling of the coronary sinus into the left atrium obviates this potential source of interatrial communication.

Diagnosis of tetralogy of Fallot with anatomically corrected malposition of the great arteries and single coronary artery by multidetector CT.

We present a case of an 8-year-old boy diagnosed as a tetralogy of Fallot with anatomically corrected malposition of the great arteries by echocardiography and cardiac catheterization. Multidetector CT nicely elucidated the course of the single coronary artery from the right coronary cusp, which traverses across the right ventricular outflow tract.

Fetal cardiovascular and other defects induced by thalidomide in cats.

Timed pregnancies were induced in cats by synchronizing gonadotropin-stimulated estrus and ovulation with natural mating. The cats were given daily oral doses of thalidomide as follows: 10 mg/kg on days 10-20 of pregnancy, 240 mg/kg on days 10-14, and 120, 240, and 480 mg/kg on days 15-17 or 18-20 of pregnancy. Fetuses were delivered by cesarean section on day 44 or 45 or earlier if threatened abortion was considered imminent. A wide variety of cardiovascular anomalies was observed on gross and microscopic examination including the following ventricular septal defect, right atrial distension primarily involving the coronary sinus, malpositioned great vessels, and narrowed left ventricular chamber with hypertrophied walls. The overall incidence of these anomalies appeared related to dose and treatment period.

The coronary arteries in hearts with discordant atrioventricular connections.

Gross morphologic study of 14 hearts with congenitally corrected transposition or discordant atrioventricular connections and double-outlet right ventricle or pulmonary atresia disclosed consistently the origins of the coronary arteries from two aortic sinuses. With usual atrial arrangement, the artery arising in sinus 1 (right-hand facing), as seen from the noncoronary aortic sinus, supplied the morphologically right ventricle. Coronary blood supply to the morphologically left ventricle usually came from sinus 2 (left-hand facing), although in two hearts the circumflex branch was a continuation of the artery from sinus 1. The sinus nodal artery arose from the circumflex coronary artery, and histologic studies of two hearts demonstrated that blood supply to the anterior atrioventricular node also came from this vessel. Early branching and entrapment in fat or right ventricular muscle, as well as malalignment of aortic and pulmonary sinuses, occurred frequently. These findings may have implications for coronary arterial transfer in the double switch operation in hearts with discordant atrioventricular connections.

Ventricular inversion with normally connected great vessels in situs solitus (atrioventricular discordance with ventriculoarterial concordance).

A patient with ventricular inversion, normally connected great vessels, and aortic valvular atresia is presented. The case represents an association of two rare situations. The first of these is normally connected great vessels with ventricular inversion. The second is the association of commonly occurring aortic valvular atresia with ventricular inversion.

Two cases of left-sided tricuspid atresia with situs solitus L-bulboventricular loop and L-transposition of the great arteries.

Two cases of extremely rare type of tricuspid atresia are presented. Both possessed left-sided tricuspid atresia, situs solitus of viscera and atria, 1-bulboventricular loop and 1-transposition of the great arteries. These anomalies are typical tricuspid atresia with 1-transpositions. The importance of bulboventricular loop in tricuspid atresia is emphasized because the atretic tricuspid valve is right-sided in the heart with solitus and d-loop, and is left-sided in the heart with solitus and 1-loop.
