Atrial septal defect echocardiography ostium secundum
Introduction
Overview
Overview
Echocardiography may be used as a diagnostic tool in the evaluation of an atrial septal defect. Common malformations of the septal wall include: ostium primum, ostium secundum, sinus venosus, and patent foramen ovale. Uncommonly, a defect may occur in the coronary sinus. Specific characteristics exist in echocardiography to identify these various classifications of atrial septal defects.

Echocardiography
An ostium secundum defect can be identified on an echocardiogram in many ways.
- A subcostal 4 chamber view serves as the best plane to visualize the anatomy of the ostium secundum.
- Can be visualized by examination of the middle of the septum in the area of the fossa ovalis where it occurs.
- Ostium secundum defect is the most common type of ASD.
