2025年3月3日 · Atrial septal defect (ASD) is the second most common congenital heart defect after ventricular septal defect (VSD). Diagnosis is often delayed until adulthood when complications arise such as atrial arrhythmias or pulmonary hypertension.

2015年12月26日 · Atrial septal defect (ASD) is one of the most commonly recognized congenital cardiac anomalies in adults. Knowledge of the embryologic development of the atrial septum provides the basis for understanding the pathophysiology, anatomy, and …

2016年1月11日 · Any defect in the atrial septum other than a normal patent foramen ovale represents an atrial septal defect (ASD). ASDs are classified according to their embryogenesis, their location relative to the fossa ovalis, and their size.

This case features the classic association of an atrial septal defect (ASD), upper sinus venosus type, with partial anomalous pulmonary venous return (PAPVR) into superior vena cava. This patient had a cardiac ultrasound examination beforehand which found: ASD septum secundum and most likely sinus venosus as well, with a gap of 26mm.

Sinus venosus ASD is caused by abnormal incorporation of the right horn of the sinus venosus into the right atrium during normal embryonic development, resulting in abnormal insertion of the caval veins. 8 There is an almost equal prevalence of SVASD between male and female patients; this is in contrast to the more common secundum ASD in which ...

2025年3月4日 · A secundum atrial septal defect (ASD) is the most common congenital abnormality of the interatrial septum. It describes a defect in the center of the interatrial septum in the region of the fossa ovalis and is most commonly due to a discontinuity in the portion of the septum derived from the embryologic septum primum 1 .

Atrial septal defects (ASD) represent 10-15% of congenital cardiac abnormalities. Sinus venosus type of ASD accounts for 10% of ASDs and only 1% of all congenital heart lesions

Sinus venosus atrial septal defect (SV-ASD) can be a challenging diagnostic problem. It can present with non-specific signs and symptoms and, on imaging, can mimic other causes of right heart dilatation.
