Category: Anatomy

Abstract:

The atrial septal defect of ostium primum type with cleft anterior mitral leaflet is a rare

congenital cardiac defect. It contributes for about 4% of congenital heart diseases and occurs in 2 in 10000 live births. A 12 year old girl's echocardiography showed this anomaly when the patient presented with breathlessness to the Department of Radiology, Chettinad Medical College and Research Institute, Chennai. This study focuses on the anatomical knowledge along with embryologic development of inter atrial septum and endocardial cushions which provide the basis for better understanding of pathophysiology and clinical manifestations of this rare anomaly.

Keywords: Atrial septal defect (ASD), ostiumprimum, cleft mitral leaflet, endocardialcushion, atrioventricular (AV)
