CTICasesComplete Atrioventricular Canal Defect Post-Repair
Imaging findings
CT in a 2-year-old child demonstrates postoperative findings of a repaired complete atrioventricular (AV) canal defect, showing surgical patches closing the atrial and ventricular septal defects and correcting the common AV valve.
Key takeaways
Complete AV canal defect is a congenital heart defect characterized by ASD, VSD, and a single common AV valve, frequently associated with trisomy 21. Surgical repair is performed in early infancy and requires closure of the shunts and creation of separate mitral and tricuspid valves.
