Summary
A novel "Swiss-cheese" ventricular septal defect repair used a combination patch technique. This approach offers a potential alternative to the Fontan operation for complex septal defects.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Sieve-like "Swiss-cheese" ventricular septal defects (VSDs) present complex surgical challenges.
- Conventional management may involve palliative procedures like the Fontan operation.
- Surgical closure requires precise defect delineation and repair strategies.
Observation:
- A 7-year-old boy with a history of neonatal pulmonary artery banding had a complex "Swiss-cheese" VSD.
- The defect involved high-, mid-, and low-trabecular septal regions.
- A right ventriculotomy facilitated access and division of muscle trabeculations.
Findings:
- A combination sandwich patch technique was employed for near-complete VSD closure.
- Division of septal and moderator bands aided in defining defect margins.
- The surgical approach successfully addressed the multi-focal nature of the defect.
Implications:
- This combination patch technique provides a viable surgical option for complex "Swiss-cheese" VSDs.
- It may offer an alternative to the Fontan operation in select pediatric cases.
- Further research can explore the long-term outcomes of this innovative repair strategy.
