A primum atrial septal defect is diagnosed on transthoracic echocardiography. The 12-lead ECG will show an incomplete right bundle branch block and left axis deviation (in contrast to the secundum ...

It is important to note that atrial septal defect is a birth defect of the heart in which there is a hole in the wall (septum) that divides the upper chambers (atria) of the heart. The size of this ...

When an atrial septal defect is present, some oxygen-rich blood that should have been pumped to the body flows from one side of the heart to the other. This blood is then pumped to the lungs. This ...

Background— Sinus venosus atrial septal defect (SVASD) differs from secundum atrial septal defect by its atrial septal location and its association with anomalous pulmonary venous connection (APVC).

[4] Echocardiography evaluation of iatrogenic atrial septal defect after combined procedure of catheter ablation and left atrial appendage closure for atrial fibrillation. Scientific Reports (2025).

the murmur of an ASD does not increase in intensity with inspiration like that of pulmonic stenosis. A secundum atrial septal defect is diagnosed on transthoracic echocardiography. The 12-lead ECG ...

Atrial septal defect closure techniques have evolved considerably over recent decades. Traditional surgical repair, once the mainstay of treatment for congenital heart anomalies, has gradually ...
