Jan 23, 2024 · An atrial septal defect (ASD) is a heart condition that you're born with. That means it's a congenital heart defect. People with an ASD have a hole between the upper heart chambers.

What Is an Atrial Septal Defect? An atrial septal defect, or hole between your two atria, allows abnormal blood flow between them. An atrial septal defect (ASD) is a hole in the atrial septum, which is the wall that separates your heart’s two upper chambers (atria).

Oct 10, 2006 · There are 3 major types of ASDs or interatrial communications: ostium secundum, ostium primum, and sinus venosus (Figure 1 A) defects. The ostium secundum is a true defect of the atrial septum and involves the region of the fossa ovalis.

Atrial septal defect (ASD) is a common congenital abnormality that occurs in the form of ostium secundum, ostium primum, sinus venosus, and rarely, coronary sinus defects. Pathophysiologic consequences of ASDs typically begin in adulthood, and ...

Jan 21, 2025 · Atrial septal defect (ASD) is one of the most common types of congenital heart defects, affecting about 25% of children (see Image. Atrial Septal Defect). An ASD occurs when the communication between the right and left atria persists after birth.

Mar 3, 2025 · 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.

Transcatheter closure has become an accepted alternative to surgical repair for ostium secundum atrial septal defects (ASD). However, large ASDs (>38 mm) and defects with deficient rims are usually not offered transcatheter closure but are referred for surgical closure.

When a person is suspected of having an ASD based on the findings of an incomplete right bundle branch block with a rSr' or rSR', the frontal plane QRS should be examined. The frontal plane QRS is the most helpful clue to distinguish between an ostium secundum ASD and an ostium primum ASD.

An Ostium secundum atrial septal defect is a type of congenital heart defect called an atrial septal defect (ASD). An ASD is a hole in the wall (septum) between the two upper chambers of the heart (the atria).

Dec 26, 2015 · 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 …
