Complex aortopulmonary window in a single ventricle setting: Technical considerations for staged palliation.

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Congenital Heart Disease

Background:

• Aortopulmonary window (APW) and large ventricular septal defect (VSD) can present as a functional single ventricle, posing complex surgical challenges.
• Staged palliation is a critical approach for managing complex congenital heart defects that result in single-ventricle physiology.
• Effective surgical strategies are essential for improving outcomes in neonates with severe cyanotic heart disease.

Observation:

• A case of a neonate with a combined aortopulmonary window (APW) and large ventricular septal defect (VSD) was successfully managed surgically.
• The anatomical complexity presented as a functional single ventricle, necessitating a tailored surgical approach.
• The patient underwent staged palliation, a multi-step surgical process designed to gradually reroute blood flow.

Findings:

• The surgical team successfully navigated the technical complexities associated with this rare combination of congenital heart defects.
• Key technical considerations during the staged single-ventricle palliation were identified and addressed.
• The successful management underscores the feasibility of staged palliation in complex single-ventricle cases.

Implications:

• This case report provides valuable insights into the surgical management of APW with large VSD, mimicking single-ventricle physiology.
• Highlighting technical considerations can guide surgeons in planning and executing staged palliation for similar complex congenital heart cases.
• Improved understanding of surgical techniques may lead to better long-term outcomes for patients with single-ventricle defects.
