17 Feb 2012 Atrial septal defect (ASD) is a congenital cardiac disorder. It is caused by the spontaneous malformation of the interatrial septum resulting in

We have reviewed the various interatrial septal pathologies and discussed their congenital associates, clinical significance, and management. The true atrial septum is made up of the flap valve of the foramen ovale (septum primum) and part of its anteroinferior margin (Figure 2). The superior rim of the fossa or the septumsecundumis the infolded wall between the SVC and the right pulmonary veins (PV). This is referred to as the interatrial groove and is not a true septum. The septum primum, a septum which grows down to separate the primitive atrium into the left atrium and right atrium, grows in size over the course of heart development.

There are many different congenital abnormalities and acquired pathologies involving the interatrial septum. Differentiation of these pathologies significantly affects patient management. We have reviewed the various interatrial septal pathologies and discussed their congenital associates, clinical significance, and management.

The interatrial septum is thin and may be diffi-cult to identify on CT scans. A small amount of fat can be present within the interatrial septum, allowing it to be identified at CT (7). Typically, fat within the interatrial septum spares the fossa ovalis. If the amount of fat within the septum is small, the fossa ovalis may not be readily

Claudio Lipomatous hypertrophy of the interatrial septum is a rare, but increasingly recognized, anomalous developmental or neoplastic lesion of the heart. This entity was first described in 1964 at autopsy and is identified before death based on its distinctive characteristics on echocardiography, computed tomography, and magnetic resonance imaging. The interatrial septum is the structure that divides the primary atrium into the right and left atrial chambers.Starting the fifth week of gestation, the septum primum begins to develop, growing toward the endocardial cushions.

Lipomatous hypertrophy of the interatrial septum is a rare, but increasingly recognized, anomalous developmental or neoplastic lesion of the heart. This entity was first described in 1964 at autopsy and is identified before death based on its distinctive characteristics on echocardiography, computed tomography, and magnetic resonance imaging. An atrial septal defect (ASD) is a hole in the wall (septum) between the two upper chambers of your heart (atria). The condition is present at birth (congenital). Small defects might be found by chance and never cause a problem.
