Successful correction of type C complete atrioventricular canal associated with tetralogy of Fallot. A case report
Insights
This case report details the successful surgical repair of tetralogy of Fallot with complete atrioventricular canal. The described technique addresses challenges in recognizing and completely closing septal defects, improving outcomes for this complex congenital heart defect.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
- Cardiac Anatomy
Background:
- Tetralogy of Fallot is a complex congenital heart defect.
- Complete atrioventricular canal (CAVC) Type C is a rare and challenging associated anomaly.
- Surgical repair of this combined condition has a historically high mortality rate.
Observation:
- The eighth reported case of successful surgical repair of tetralogy of Fallot with complete atrioventricular canal, Type C.
- Pre-operative recognition of associated anomalies and complete closure of septal defects are critical.
- The patient presented with both atrial and ventricular septal defects.
Findings:
- Atrial and ventricular septal defects were successfully closed using two separate patches.
- Undivided hemivalves were attached to septal patches with interrupted mattress sutures.
- Right ventricular outflow tract obstruction was relieved via infundibulectomy, pulmonary valvotomy, and a Dacron patch graft.
Implications:
- This successful repair highlights a viable surgical strategy for a complex congenital heart defect.
- Improved pre-operative recognition and meticulous surgical technique can reduce mortality.
- The patient achieved satisfactory condition one year post-surgery without medication, suggesting long-term positive outcomes.
Abstract:
This is the eighth reported case of successful repair of tetralogy of Fallot associated with complete atrioventricular canal, Type C. The high surgical mortality rate in this combination is in part due to failure to recognise the associated anomaly pre-operatively, and in part to not closing the ventricular septal defect completely. In our case the atrial and ventricular septal defects were closed with two separate patches. The undivided hemivalves were attached to the septal patches by interrupted mattress sutures. The right ventricular outflow tract obstruction was relieved by infundibulectomy, pulmonary valvotomy and the placement of a Dacron patch over the infundibulum. One year postoperatively, the condition of the patient is satisfactory without the need for diuretics or digitalis.
