It results from the inadequate closure of the central hole in the septum primum by the septum secundum – this also produces the fossa ovalis defect. This is the most common form of ASD. Sinus venosus defect: In the superior portion of the atrial septum which generally extends into the superior vena cava.
The following description is relevant to all subtypes of defects but there are special additional considerations with primum ASDs described below. Atrial Septal Defect (ASD) is the third most common congenital heart defect.

2021-03-11 ASD Types of ASD: ASD are most frequently diagnosed during adulthood and are more frequent in women than in men. Types of ASD are as follows: * Secundum ASD: located at the level of the oval fossa; it is called secundum ASD despite the fact that the oval fossa is the septum primum (Fig. 17). Ostium secundum ASD- Patients with ostium secundum ASDs often develop atrial fibrillation or atrial flutter, and this occurs with a higher incidence with increasing age and with pulmonary hypertension.

The septum primum ASDs (ASD-OS1) are located underneath the fossa ovalis and usually originate from a fusion defect of the endocardial cushions.

Frequency 1/1500 need closure. 10-20% of adults have some sort of inter-atrial communication. Physiology Holes between the atria are usually remnants of the foramen ovale, in which the flap valve does not fit across the foramen well.
The frontal plane QRS is the most helpful clue to distinguish between an ostium secundum ASD and an ostium primum ASD. In primum defects left axis deviation is seen in most patients with an axis of > -30 degrees and very few patients have right axis deviation. In contrast ostium secundum defects have an axis between 0 degrees and 180 degrees with most cases to the right of 100 degrees. 
Primum ASD. A primum ASD is a hole in the inferior and posterior portions of the atrial septum adjacent to the AV valves. It is also associated with a cleft in the mitral valve which may result in a leak, known as mitral regurgitation. Correction of this defect requires surgery and consists of patch closure of the ASD and repair of the mitral valve cleft. Less common than the secundum type atrial septal defect, a primum ASD is usually small and less commonly requires intervention when it occurs in isolation.

The following description is relevant to all subtypes of defects but there are special additional considerations with primum ASDs described below. Atrial Septal Defect (ASD) is the third most common congenital heart defect. There are three main types of ASD: ostium secundum, ostium primum and and sinus venous.

Determination of QRS axis is very important in the differential diagnosis of ostium secundum and ostium primum ASD. Right axis deviation is not observed in Ostium secundum atrial septal defect is the most common form of this group of heart In such rare cases, the two forms, ostium primum and ostium secundum At birth, the septum secundum and septum primum slap shut, and then fuse and close off this foramen ovale so that we can rely on our own lungs for oxygen.

Ostium secundum defect . This defect is in the region of the foramen ovale. The atrioventricular (AV) valves are normal. The defect is usually isolated, found incidentally, and 3 times more common in girls. ASD overview and secundum ASD Atrial septal defect (ASD) is the commonest congenital heart disease in the adult, barring of course bicuspid aortic valve.
