Spanish cardiac catheterization and coronary intervention registry. 34th official report of the Interventional Cardiology Association of the Spanish Society of Cardiology (1990-2024).

Introduction and objectives: This report presents the 2024 activity data from the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC).

Methods: All interventional cardiology laboratories in Spain were invited to complete an online survey. Data analysis was conducted by an external company and then reviewed and presented by the ACI-SEC board.

Results: A total of 118 hospitals participated, with a marked increase in the number of catheterization laboratories. The number of diagnostic procedures rose by 3.6%. Percutaneous coronary interventions (PCI) also increased. Although PCI volumes grew compared with 2023, the trend toward a reduction in the number of stents used was confirmed, with greater use of drug-coated balloons both as standalone treatment and in hybrid strategies (14.3% of PCIs involved drug-coated balloons). Overall, the use of intracoronary diagnostic techniques increased, with 10.6% of PCIs guided by intracoronary imaging. Plaque modification techniques also continued to grow. Primary PCI increased slightly and remained the predominant treatment for myocardial infarction (98%). Structural interventions continued to expand, with substantial growth in transcatheter aortic valve implantation, percutaneous edge-to-edge mitral repair, tricuspid interventions, and left atrial appendage closure. Interventional treatment for acute pulmonary embolism increased again in 2024, especially with dedicated devices.

Conclusions: The 2024 Spanish cardiac catheterization and interventional cardiology registry showed overall growth in all procedures, both coronary and structural.
