Spanish cardiac catheterization in congenital heart diseases registry. Third official report from the ACI-SEC and the GTH-SECPCC (2022).

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 annual activity report for 2022.

METHODS

All Spanish centers with catheterization laboratories and interventional activity in congenital heart diseases were invited to participate. Data were collected online and analyzed by an external company, together with the members of the ACI-SEC and the GTH-SECPCC.

RESULTS

A total of 22 centers participated (19 public and 3 private). Interventional data on adult congenital diseases contributed by another 99 hospitals to the Registry of Cardiac Catheterization and Interventional Cardiology of the ACI-SEC in 2022 were incorporated into the analysis. A total of 1141 diagnostic studies (4.3% more than in 2021) and 2508 interventional catheterizations (61.5% more than in 2020) were registered. The most frequent procedures were atrial septal defect closure (1135 cases), percutaneous closure of patent ductus arteriosus (262 cases), and pulmonary branch artery angioplasty (234 cases). The most significant increases in volume were related to balloon aortic valvuloplasty (48.9%), atrial septal defect closure (45.2%), and ventricular septal defect closure (40.7%). Interventional procedures were successful in 97.6%, with major procedural complications occurring in 1.4% and in-hospital mortality in 0.2%.

CONCLUSIONS

This report is the third publication of the Spanish Cardiac Catheterization in Congenital Heart Diseases Registry. Both diagnostic and interventional procedures substantially increased, particularly in balloon aortic valvuloplasty, atrial septal defect closure, and ventricular septal defect closure. Most interventional techniques continue to demonstrate excellent safety and effectiveness outcomes.
