The Working Group on Cardiac Catheterization and Interventional Cardiology presents its annual report on the data from the registry of the activity in 2015.

All Spanish hospitals with catheterization laboratories were invited to voluntarily contribute their activity data. The information was collected online and analyzed mostly by an independent company.

In 2015, 106 centers participated in the national register; 73 of these centers are public. A total of 145 836 diagnostic studies were conducted, among which 128 669 were coronary angiograms. These figures are higher than in previous years. The Spanish average of total diagnoses per million population was 3127. The number of coronary interventional procedures was very similar (67 671), although there was a slight increase in the complexity of coronary interventions: 7% in multivessel treatment and 8% in unprotected left main trunk treatment. A total of 98 043 stents were implanted, of which 74 684 were drug-eluting stents. A total of 18 418 interventional procedures were performed in the acute myocardial infarction setting, of which 81.9% were primary angioplasties. The radial approach was used in 73.3% of the diagnostic procedures and in 76.1% of interventional ones. The number of transcatheter aortic valve implantations continued to increase (1586), as well as the number of left atrial appendage closures (331).

An increase in diagnostic and therapeutic procedures in acute myocardial infarction was reported in 2015. The use of the radial approach and drug-eluting stents also increased in therapeutic procedures. The progressive increase in structural procedures seen in previous years continued.
