Types of Atrial septal defect
Four types of interatrial communications exist:
[A] Ostium primum defects
[B] Ostium secundum defects
[C] Sinus venosus defects
[D] Coronary sinus defects
Which of the following is true Atrial septal defect?
[A] Ostium primum defects
[B] Ostium secundum defects
[C] Sinus venosus defects
[D] Coronary sinus defects
True Atrial septal defect
- True Atrial septal defect – Ostium secundum defects – The defect in septum is surrounded by true atrial septal tissue
- All the others are atrial-level shunts- not being surrounded by true atrial septal tissue
Gerbode defect
