In brief: Complex ASD/VSD

Also known as an atrio-ventricular septal defect, it is a type of congenital heart defect.
There is a an ASD and vsd together creating a defect (hole) in the center of the heart. There is also one common av valve , rather than 2 distinct valves (mitral and tricuspid valves). It is commonly but not necessarily associated with down syndrome. Surgical repair is required in infancy.

In brief: Crux of the heart

An a-v canal defect involves several structures at the center (crux) of the heart.
It is characterized by a vsd, ASD and a common a-v valve. The left portion of the a-v valve can have a cleft that can cause (mitral) valve regurge. Because of the significant left to right shunt, and a typical association with down syndrome, these patients are more prone to developing pulmonary hypertension early.
