Atrioventricular canal defect (also called endocardial cushion defect or atrioventricular septal defect) is a large hole in the septum, accompanied by abnormal tricuspid and mitral valves that are not formed as individual valves.
Pulmonary artery banding, narrowing the pulmonary artery with a band to reduce blood flow and pressure in the lungs, is used for ventricular septal defect, atrioventricular canal defect, and tricuspid atresia.
