Abstract

Supravalvar mitral ring (SVMR) is a rare cause of congenital mitral stenosis. It can occur in isolation but often coexists with other cardiac anomalies, such as a ventricular septal defect or left-sided obstructive lesions. Conversely, a complete atrioventricular septal defect (AVSD) is a much more common anomaly. An AVSD may be associated with other major cardiac defects, such as tetralogy of Fallot, transposition of the great arteries, or double-outlet right ventricle. The authors describe what they believe is the first case of SVMR and complete AVSD occurring together; the SVMR was diagnosed by two-dimensional echocardiography, and its morphology could be more accurately delineate using three-dimensional echocardiography.

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.
