PURPOSE:To evaluate phase-contrast magnetic resonance (MR) imaging for sizing of secundum atrial septal defects (ASDs) and inflow MR angiography for detection of associated venous anomalies in pediatric patients with inconclusive transthoracic echocardiographic (TTE) results.

Early diagnosis is the single most important step in the definitive management of the condition; otherwise, only conservative treatment can be offered. In this report, we present the case of a 20-year-old female patient diagnosed with Eisenmenger syndrome secondary to a large secundum ASD. The patient responded well to medical treatment.

The ostium primum ASD is the second most common type. An ASD is characterized by a defect in the interatrial septum that allows pulmonary venous return to pass from the left to the right atrium (i.e., left-to-right shunt), resulting in right atrial and right ventricular chamber dilation. There are four types of ASD. The first type is an ostium secundum defect. A more robust method for demonstrating a secundum ASD is to acquire phase-contrast images parallel to the septum at the level of the fossa ovalis. With this method, blood flow through the interatrial septum travels perpendicular to the imaging plane and easily detected. The secundum ASD is usually an isolated lesion, but it can be seen in association with other forms of congenital heart disease. The two common associations are mitral stenosis (Lutembacher syndrome) and absent radius (Holt–Oram syndrome).

Why cardiac MRI is beneficial: Cardiac MRI is well suited for the examination of an ASD because it can accurately quantify the shunt, and its effect on cardiac structure and function. It can directly visualize blood flowing across the ASD. It is totally non-invasive and does not require contrast. 3. . The commonest form of this defect (so called Secundum ASD) is a defect in the central part of the "Atrial Septum" (the partition separating the Atriums).

The Amplatzer Septal Occluder (ASO) is designed for percutaneous closure of atrial septal defect (ASD), the fourth most common congenital cardiac anomaly. ASD closure is indicated within the setting of right cardiac chamber enlargement, prevention of paradoxical embolism, net left to right shunting, and to prevent arrythmias (1).

Why cardiac MRI is beneficial: Cardiac MRI is well suited for the examination of an ASD because it can accurately quantify the shunt, and its effect on cardiac structure and function.

It can directly visualize blood flowing across the ASD. This echocardiogram shows an ostium secundum atrial septal defect, which is most common type of defects of this septum. It is located in a position of foramen ovale.
