Insights
Intracardiac repair of complete atrioventricular canal and tetralogy of Fallot in nine pediatric patients showed no hospital deaths. Recommendations include early palliation and tailored surgical techniques for optimal outcomes.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
Background:
- Complete atrioventricular canal (CAVC) and tetralogy of Fallot (TOF) are complex congenital heart defects.
- Surgical repair of combined CAVC and TOF presents significant challenges.
Purpose of the Study:
- To evaluate the outcomes of intracardiac repair for combined CAVC and TOF in pediatric patients.
- To identify optimal surgical strategies and patient selection criteria.
Main Methods:
- Retrospective review of nine patients undergoing intracardiac repair between 1982 and 1989.
- Preoperative diagnosis confirmed by two-dimensional echocardiography, cardiac catheterization, and cineangiography.
- Surgical techniques included combined atrial and ventricular approach for ventricular septal defect repair and various outflow tract reconstructions.
Main Results:
- No hospital mortality was observed in the nine patients.
- Patients ranged from 6 months to 7 years old; six had prior systemic-pulmonary artery shunts.
- Postoperative complications included one death from meningitis two years after repair.
Conclusions:
- Intracardiac repair of combined CAVC and TOF is feasible with no in-hospital mortality.
- Recommendations include early palliation, complete repair for patients older than 4-5 years, tailored surgical techniques, and meticulous postoperative care.
Abstract:
Nine patients with complete atrioventricular canal and tetralogy of Fallot underwent intracardiac repair of both anomalies between 1982 and 1989. The ages of the patients ranged from 6 months to 7 years. Six of the 9 had one or more previous systemic-pulmonary artery shunts. Two-dimensional echocardiography showed diagnostic characteristics of both malformations in all patients. The diagnosis was confirmed by cardiac catheterization and cineangiography. The ventricular septal defect was repaired by a combined right atrial and ventricular approach in every patient. Outflow tract reconstruction was performed with the use of a transannular patch (4), infundibular patch (4), and a valved conduit (1). There were no hospital deaths. Meningitis was responsible for the death of a patient 2 years after repair. We recommend early palliation, complete repair in those older than 4 or 5 years, surgical technique depending on the anatomical findings, combined atrial and ventricular approach, 2 separate patches to close the ventricular septal defect in required cases, adjusted correction of the right ventricular outflow tract, and careful postoperative care.
