Changes in the radiological appearances of the hilar region of the lungs may indicate that the pulmonary blood supply is not normal. In atresia of the pulmonary valve, the pulmonary arteries may be absent, but more often they are small and may be supplied or supplemented by anomalous vessels. Then blood reaches the lungs mainly by the bronchial arteries or by other collaterals and there is litt...
We used non-invasive high frequency ultrasound to screen N-ethyl-N-nitrosourea mutagenized mouse fetuses for congenital cardiovascular anomalies. We ultrasound scanned 7546 mouse fetuses from 262 mutagenized families, and identified 124 families with cardiovascular defects. Represented were most of the major congenital cardiovascular anomalies seen clinically. The ENU-induced mutations in sever...
Ninety-two patients had corrective operation for truncus arteriosus between 1967 and 1975. During the first 30 days after surgery, 23 patients died. No significant differences appear between early mortality and sex, type of truncus, variations in pulmonary arterial anatomy, truncal valve regurgitation, associated anomalies, previous operation, or duration of extracorporeal circulation. Greater ...
OBJECTIVE Neonatal primary repair has progressively become the treatment of choice for truncus arteriosus with encouraging survival. However, use of valved conduits to reconstruct the right ventricular outflow tract (RVOT) inevitably induces reintervention. This study estimates survival and rate of catheter-interventional and surgical reinterventions. METHODS Thirty-five consecutive neonates ...
Between 1971 and December 1976, 27 children with congenital heart disease underwent right ventricular outflow tract reconstruction with conduits incorporating a Björk-Shiley valve. The conditions corrected were pulmonary atresia with ventricular septal defect (14 patients), truncus arteriosus (6 patients), and complex disease (7 patients). At operation the children were aged from 12 days to 16 ...
Objective: To compare the prevalence at live birth and the spectrum of cardiovascular malformations in infants born to diabetic mothers with pre-existing diabetes with that in infants of non-diabetic mothers. Design: Prospective study of all live births in the resident population of one health region, with recording of details of the outcome of all pregnancies of women with pre-existing diabete...
