Abstract

This is a report on the anatomical characteristics of 17 cases of tricuspid atresia. Three of these cases had a discrepancy between the type of bulboventricular loop (dextro) and the position of the great arteries (the aorta being to the left of the pulmonary artery). In these a characteristic type of ventricular septal defect, located just beneath the tissue of the semilunar valves was found. In 3 cases with cardiac dextroversion and juxtaposition of the atrial appendages the great arteries were on the same frontal plane and there was a separation between the semilunar and the anterior mitral leaflet. One case was associated with a double outlet left ventricle, a D-malposition of the great arteries, and a bilateral subaortic and subpulmonary conus. Among the 6 cases with transposition of the great arteries, the ventricular septal defect was large in 2 (34.4%) only. In the analysis of the 13 cases with intact ventricular septa (2 cases) or restrictive (small and medium-sized) ventricular septal defects (11 cases) obstructive anomalies of the vessel arising from the right ventricle were found in 12 (92.3%). These anomalies involved the aorta in 4 cases. (34.4%) and the pulmonary artery in 8 (66.6%). In the study of the 4 cases w...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
