Secundum atrial septal defect (ASD), located in the central part of the atrial septum within the floor of the fossa ovalis, is the most common type of ASD. It is a shunt between the systemic and pulmonary circulations. Patients with an isolated ASD often remain asymptomatic early in life.

Ostium Secundum atrial septal defect (OS-ASD): Most common type of ASDs. It is located in the middle of interatrial septum. Ostium primum defect: This occurs in the lower part of the inter-atrial septum, and can be associated with mitral valve abnormalities and other CHDs. Sinus venosus defect in inter-atrial septum (superior vena cava {SVC} & inferior vena cava {IVC} types): This The muscular part of the atrial septum is derived from the septum secundum fused with the septum primum . 2. The ostium secundum is covered by the septum secundum .

The ostium primum defect is within the spectrum of the atrioventricular (AV) septal defects ( Figure 1 B; also known as AV canal defects or endocardial cushion defects), the complete form of which also includes a large ventricular septal defect and a common The most common form of an atrial septal defect is presence of ostium secundum type in the middle of the septal defect, while less common is ostium primum type, located lower in the septum and in these cases there are abnormalities in the mitral tricuspid valves. In both cases, normal oxygen saturated blood from the left atrium passes into the right atrium in thous way they increase cardiac output of right ventricle and pulmonary flow.

Sinus venosus: they comprise 5% of ASD. They are locatedin the superior or inferior region of the interauricular septum, near the superior or inferior vena cava respectively. Ostium primum: they are the second most frequent ASD, up to 15%. It is located near the crux of the heart, and is usually associated with other defects such as mitral cleft, presence of common atrioventricular valve, or inlet ventricular septal defect. secundum ASD. 60-90% of all ASDs.
