AV Canal repair is a critical surgery that is performed within the first two or three months of a new born baby. The surgeon closes the hole with one or two patches. The patches are stitched into the heart muscle and as the child grows, the tissue grows over the patches. The repair procedure involves exposure of the atrioventricular valve. Then the specialist closes the ventricular septal defect and repairs the Left atrioventricular valve. The right specialist to consult for AV Canal repair is a cardiac surgeon and a neonatologist. The success rate for the treatment remains between 70-81%.
