High IE incidence after Melody TPVR in children warrants intensified surveillance; extends risk estimates but leaves optimal prevention strategies open.
INTRODUCTION: Infective Endocarditis (IE) has emerged to be one of the most impactful adverse complications post-transcatheter procedures, especially Transcatheter Pulmonary Valve Replacement (TPVR). We conducted a systematic review and meta-analysis with the aim of identifying the incidence of IE post-TPVR with the MELODY valve in the pediatric population. METHODS: A comprehensive literature search was performed across several prominent databases, including PubMed/MEDLINE, SCOPUS, and Science Direct. Studies compared the clinical outcomes of pediatric patients who received TPVR using the MELODY valve. Data extraction was done for variables like the total pediatric patient population that underwent TPVR with MELODY valve, mean age, the sex of the patients, the incidence rate of IE following the procedure, and the duration between the procedure and the occurrence of IE. Inverse Variance was used to estimate the incidence of IE in patients who underwent TPVR with respective 95% confidence interval (CI). RESULTS: In total, 4 studies with 414 pediatric patients who underwent TPVR using the MELODY valve were included in the study. The mean age of the study population was 12.7 ± 3.11 years. The pooled incidence of IE following TPVR with MELODY valve in the pediatric population was 17.70% (95% Cl 3.84-31.55; p<0.00001). Additionally, the mean length of duration to develop IE following TPVR with MELODY valve in the pediatric population was 2.18 years (95% Cl 0.35-4.01; p<0.00001). CONCLUSION: Our meta-analysis reveals that IE post-TPVR with MELODY valve in pediatric patients is a significant complication, clinically and statistically. Further research needs to be done to understand the risk factors and develop better management strategies.

Veldurthy et al. (2024) conducted a meta-analysis in Congenital heart disease requiring transcatheter pulmonary valve replacement (n=414). Transcatheter pulmonary valve replacement (TPVR) with the MELODY valve was evaluated on Incidence of infective endocarditis following TPVR (95% CI 3.84-31.55, p=<0.00001). Transcatheter pulmonary valve replacement with the MELODY valve in pediatric patients was associated with a pooled infective endocarditis incidence of 17.70%.
