# Percutaneous closure of aortopulmonary window using a muscular ventricular septal defect occluder. Instituto Nacional de Salud del Niño San Borja Lima-Peru. Case report

## TL;DR

A rare heart defect called aortopulmonary window was successfully treated in an infant using a minimally invasive device, avoiding surgery.

## Contribution

This case report demonstrates the successful use of a muscular ventricular septal defect occluder for percutaneous closure of an isolated aortopulmonary window.

## Key findings

- An infant with an isolated aortopulmonary window was successfully treated with a muscular ventricular septal defect occluder.
- The procedure was completed without complications and the patient was discharged within 48 hours.
- Percutaneous closure is a viable alternative to surgery for this rare defect when appropriate devices are used.

## Abstract

The aortopulmonary window is a rare congenital heart defect. Isolated aortopulmonary window, without other associated anomalies, accounts for up to 25% of all cases. Surgical closure has long been, and remains, the gold standard in many cardiovascular centres. However, percutaneous closure has emerged as a viable alternative using various types of occluder devices, selected based on the morphology, size, and rims of the defect to minimise complications such as valvular interference or coronary ostial obstruction. We report the case of an infant with an isolated aortopulmonary window successfully treated with percutaneous closure using a muscular ventricular septal defect occluder device, with no complications. The patient was discharged 48 hours after the procedure.
