Atrioventricular Canal Defect
Also known as: atrioventricular septal defects, endocardial cushion defects, ECD
What are atrioventricular canal defects?
As the heart is developing in the unborn fetus, it typically develops walls and valves between the four chambers. With atrioventricular canal defect, the walls and chambers do not fully develop, and blood can flow freely between these areas. This can lead to a variety of developmental problems.
What causes atrioventricular canal defects?
Atrioventricual canal defects are birth defects that occur very early on in the development of a fetus. The exact reason they occur is not known.
What are the symptoms of atrioventricular canal defects?
Symptoms can include failure of the baby to grow, rapid breathing and heartbeat, sweating, swelling, frequent infections, fatigue and a blue or pale color to the skin and lips.
What are atrioventricular canal defects care options?
Surgery is required to correct an atrioventricular canal defect. It might require more than one.

Bidirectional Glenn Procedure
Bidirectional Glenn procedure is one in a series of surgeries performed to get a sufficient amount of blood to the lungs. It is needed when one of the heart’s ventricles doesn’t work well.
Complete Atrioventricular Canal Repair
A complete atrioventricular canal defect is a birth defect in which the heart doesn’t develop properly. It’s characterized by a hole in the center of the heart that allows blood from all four chambers to mix and not flow through the heart properly. Complete atrioventricular (AV) canal repair is a surgery to fix this defect.
