Spanish cardiac catheterization in congenital heart diseases registry. Fourth official report from the ACI-SEC and the GTH SECPCC (2023)

RESUMEN Introduction and objectives: The Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) and the Interventional Working Group of the Spanish Society of Pediatric Cardiology (GTH-SECPCC) present their 2023 annual activity report. Methods: Participation was open to all Spanish centers with cath labs and interventional programs for congenital heart disease. Data was collected online and analyzed by an external company, and members from the ACI-SEC and the GTH-SECPCC. Results: A total of 19 centers participated (15 public and 4 private). Interventional data on adult congenital diseases was contributed to the Registry of Hemodynamics and Interventional Cardiology of the ACI-SEC in 2023 by another 114 hospitals and, then, added to the analysis. A total of 1127 diagnostic studies (1.2% less than 2022) and 3856 interventional cardiac catheterizations (53.7% more than 2022) were registered, 2439 of which (65%) were performed on patients older than 18 years. The most widely performed procedures were foramen ovale closure (1498 cases), atrial septal defect closure (700 cases), transcatheter closure of the patent ductus arteriosus (344 cases) and aortic coarctation (221 cases). The most significant volume increment of cases was associated with ventricular septal defect closure (181%), foramen ovale closure (87%), and aortic coarctation (75%). Interventional procedures were considered successful in 98.3% of the cases, with rates of major procedural complication and in-hospital mortality of 1% and 0.05%, respectively. Conclusions: We present the fourth Spanish cardiac catheterization in congenital heart diseases registry with data from 2023. We observed a significant rise in interventional procedures, notably ventricular septal defect and patent foramen ovale closures. Most interventional techniques continue to demonstrate excellent safety and efficacy outcomes.
