A Wide fixed split pf S2 , a short systolic murmur and PA pulsations in left second space, a loud P2 and a hyperdyanmic RV occur in both . The following features might give a clue for OP -ASD . The septum primum ASDs (ASD-OS1) are located underneath the fossa ovalis and usually originate from a fusion defect of the endocardial cushions. • The septum secundum ASDs (ASD-OS2) are the most commonly encountered ASD, representing two thirds of all ASDs.

Se hela listan på mayoclinic.org 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. There are few reports of multi-hole ostium secundum ASD, its incidence is estimated in 4-10%. ASDs can be classified by location. An ostium secundum ASD is a hole in the center of the atrial septum.
The three most common forms of ASD are: secundum, sinus venosus, and primum defects. Secundum ASD
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.

Transcatheter treatment of atrial septal defect (ASD) and patent foramen Varenicline, an α4β2 nicotinic acetylcholine receptor partial agonist, vs sustained-release bupropion and During tilt, the AF frequency increased (6.08 ± 1.03 Hz vs. 6.20 ± 0.99 at surgery in 3 groups of pts.
In addition to the PR prolongation, individuals with a primum ASD have a left axis deviation of the QRS complex, while those with a secundum ASD have a right axis deviation of the QRS complex. Individuals with a sinus venosus ASD exhibit a left axis deviation of the P wave (not the QRS complex). 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.
