Key result
Pediatric congenital heart interventions across 32 centers show an overall in-hospital mortality of ~1.3%.
Why the study?
Systematic monitoring of outcomes is essential for improving CHD care quality, prompting an assessment of surgical volumes, diagnostic distributions, and in-hospital mortality in the Russian Federation using 2025 national registry data.
What are the surgical volumes, diagnosis distributions, and in-hospital mortality rates associated with surgical and interventional treatment for congenital heart disease and cardiac arrhythmias in pediatric patients in the Russian Federation in 2025?

What are the surgical volumes, diagnosis distributions, and in-hospital mortality rates associated with surgical and interventional treatment for congenital heart disease and cardiac arrhythmias in pediatric patients in the Russian Federation in 2025?
National registry data from 32 Russian centers in 2025 demonstrate a low overall in-hospital mortality of 1.30% across 15,634 pediatric congenital heart disease and arrhythmia procedures, though neonatal surgery with cardiopulmonary bypass remains high-risk at 9.5% mortality.

Low mortality benchmarks achieved in Russian pediatric CHD centers; extends 2024 national data but leaves generalizability open.
Introduction: Systematic monitoring of outcomes in patients with congenital heart disease (CHD) is essential for improving the quality of care. Since 2024, a national multicenter digital registry designed to consolidate data from the country’s leading expert centers has been undergoing pilot implementation in the Russian Federation. Objective: To assess surgical volumes, the distribution of diagnoses, and in-hospital mortality associated with treatment for CHD and cardiac arrhythmias in the Russian Federation using 2025 registry data. Methods: We retrospectively analyzed de-identified data from 15,634 patients treated at 32 cardiac surgery centers in the Russian Federation that provide care to patients younger than 18 years with CHD. Procedural complexity was assessed using the RACHS II risk-stratification system. Outcomes were analyzed by age group, including neonates with low birth weight. Results: Overall in-hospital mortality was 1.30% (vs. 1.42% in 2024). Open surgical procedures accounted for 48.3% of interventions, transcatheter procedures for 37.6%, and procedures for cardiac arrhythmias for 12.8%. The most common CHD diagnoses were atrial septal defect (23.96%), patent ductus arteriosus (22.42%), and ventricular septal defect (15.47%).The highest mortality was observed among neonates undergoing surgerywith cardiopulmonary bypass (9.5%). Conclusion: The 2025 data confirm a sustained decline in overall mortalityand support the effectiveness of implementing national standards. Further improvement in neonatal surgery for complex defects remains a priority. Implementation of a unified system enabling patient-level identification and personalized assessment of treatment effectiveness is also essential. Received 8 July 2026. Revised 12 July 2026.

Soynov et al. (2026) conducted an observational in Congenital heart disease and cardiac arrhythmias (n=15,634). Surgical, transcatheter, and arrhythmia interventions for congenital heart disease was evaluated on In-hospital mortality. Surgical and interventional treatment for pediatric congenital heart disease and arrhythmias across 32 Russian centers in 2025 resulted in an overall in-hospital mortality rate of 1.30%.
