Insights
Surgical repair of aortopulmonary (AP) windows often requires staging based on associated cardiac anomalies. This approach minimizes risks for complex congenital heart disease patients.
Area of Science:
- Congenital heart disease
- Pediatric cardiology
- Cardiac surgery
Context:
- Aortopulmonary (AP) window is a rare congenital heart defect.
- It frequently co-occurs with other intracardiac and extracardiac anomalies.
- Simultaneous repair of all defects is the typical surgical recommendation.
Purpose:
- To evaluate the surgical management of AP window with associated anomalies.
- To assess the outcomes of single-stage versus staged repair strategies.
- To determine if staged repair is beneficial in specific clinical scenarios.
Summary:
- Four pediatric patients with AP window and various associated anomalies (interrupted aortic arch, septal defects, patent ductus arteriosus, pulmonary artery narrowing) underwent surgical repair.
- Management strategies included single-stage repair, staged repair with initial AP window ligation, and pulmonary artery banding prior to complete repair.
- All patients demonstrated positive outcomes during follow-up periods ranging from 11 to 18 months.
Impact:
- Surgical management of AP window may necessitate a staged approach tailored to the physiological impact of associated anomalies.
- Staged repair can potentially minimize the cumulative surgical risk in complex pediatric cardiac cases.
- Individualized surgical planning is crucial for optimizing outcomes in patients with complex congenital heart disease.
Abstract:
Aortopulmonary (AP) window is an uncommon cardiac anomaly which is frequently associated with other cardiac anomalies. Concomitant repair of all intra- and extracardiac anomalies is usually recommended. Between October 1993 and July 1994, 4 patients aged 37 days, 4 weeks, 3.5 and 1.5 years, respectively, underwent repair of AP window and associated malformations. The associated anomalies consisted of interrupted aortic arch (IAA), and atrial and ventricular septal defects in the 1st patient, patent ductus arteriosus in the 2nd, inlet ventricular septal defect in the 3rd and congenital narrowing of the right pulmonary artery and a patent foramen ovale in the 4th. Extreme metabolic acidosis after repair of IAA in the 1st, dictated ligation of the AP window before repair of the intracardiac anomalies at 2 months of age. In the 2nd and 3rd, repair of the window and associated anomalies was performed in a single stage. In the 4th, left pulmonary artery banding preceded complete repair. All patients are doing well at 18, 13, 12 and 11 months, respectively, of follow-up after their last operation. Surgical management of AP window may have to be staged according to the physiological influence of the associated anomalies in each patient, to minimize the cumulative risk of complete repair.
