Insights
Surgical closure of muscular ventricular septal defects (VSD) below the trabecula saepto-marginalis is challenging. A perventricular device technique using an Amplatzer septal occluder offers a viable solution for these difficult-to-reach VSDs.
Area of Science:
- Cardiology
- Pediatric Cardiac Surgery
- Medical Devices
Background:
- Muscular ventricular septal defects (VSD) located below the trabecula saepto-marginalis present significant surgical challenges.
- Traditional transatrial or transpulmonary approaches may be difficult for these specific VSD locations.
Abstract:
Muscular ventricular septal defects (VSD) located below the trabecula saepto-marginalis are difficult to approach for surgical closure through the tricuspid valve. We present the hybrid technique of perventricular closure of VSD in 2- and 5-year old children with complex congenital heart defects, employing an Amplatzer septal occluder, dedicated to muscular type of VSD. The procedures were performed during cardiopulmonary bypass in one patient and on beating heart in the other one. The perventricular device technique may be the method of choice for closing hard to reach muscular VSD.
