This paper presents serial cardiac-catheterization data showing spontaneous functional closure of large symptomatic defects in 3 infants. One had an associated moderate-sized patent ductus arteriosus ...

To heart wire, Krishnan said: "We are describing this novel cardiac anatomy for the first time. Increased recognition of this left atrial septal pouch has the potential to cause a paradigm shift in ...

PULMONARY hypertension is a serious and relatively frequent complication of the ostiumsecundum type of defect of the atrial septum. 1–4 It increases the symptoms and disability of cardio-respiratory ...

An atrial septal defect of the secundum type is relatively common and occurs from failure of the septum secundum to develop. This results in a communication between the left and right atrium directly ...
