A Retrospective, Observational, and Descriptive Study of Pediatric Cardiac Fibroma

This study was a retrospective descriptive case series analyzing outcomes of a novel surgical approach This study aimed to evaluate a modified surgical technique-called the Sandwich Procedure-for reconstructing the heart after resection of cardiac fibromas in children. Cardiac fibroma is a rare benign tumor that can compress vital cardiac structures and cause serious symptoms such as arrhythmia, heart failure, or obstruction of blood flow. Surgical removal is often required, but large tumors may leave defects in the heart wall that are challenging to repair, especially in young children.

The Sandwich Procedure was developed at our institution to improve the strength and stability of heart wall reconstruction after tumor removal. It involves suturing two layers of treated biological tissue-both inside and outside the heart wall-to restore normal shape and function, while minimizing the risk of complications like aneurysm or bleeding. This retrospective, observational study includes pediatric patients who underwent this procedure between 2018 and 2023. We report on its surgical feasibility, short- and mid-term outcomes, and potential benefits in preserving cardiac function.
