NEOAORTIC VALVE REPAIR AND REPLACEMENT AFTER ARTERIAL SWITCH OPERATION IN CHILDREN
https://doi.org/10.51922/1818-426X.2025.1.63
Abstract
Introduction. Arterial switch operation is performed in children with transposition of the great arteries (TGA) in modern pediatric cardiac surgery. Pulmonary valve begins to function as a systemic one after arterial switch operation, that is neoaortic valve (neo-AV). Objective was to evaluate the possibilities of neo-AV repair and replacement after arterial switch operation in children with TGA.
Materials and methods. Arterial switch operation was performed in 305 children with TGA at the RSPC “Cardiology” and RSPC of Pediatric Surgery from 2004 to 2024 years. Mean age of the children was 11.2 ± 3.8 days. Simple TGA was in 213 children (69.8 %). TGA with ventricular septal defect was in 67 patients (22.0 %). Double outlet right ventricle with TGA (Taussig-Bing anomaly) was in 24 children (7.9 %). Congenitally corrected TGA with ventricular septal defect was in 1 patient (0.3 %).
Results. There were 18 deaths (5.9 %) during hospital stage after arterial switch operation, postoperative complications were diagnosed in 13 patients (4.3 %). Long-term period was studied in 253 children (83.0 %) after arterial switch operation. Mean follow-up duration was 8.1 ± 4.7 years. Neo-AV repair was performed in 1 patient (0.4 %), neo-AV replacement with mechanical prostheses was performed in 3 children (1.2 %) in long-term period after arterial switch operation.
Conclusion. It’s possible to replace neo-AV with mechanical prostheses of the required diameter in children with TGA after arterial switch operation.
