Spanish Cardiac Catheterization and Coronary Intervention Registry. 21st official report of the Spanish Society of Cardiology Working Group on Cardiac Catheterization and Interventional Cardiology (1990-2011).

INTRODUCTION AND OBJECTIVES The Working Group on Cardiac Catheterization and Interventional Cardiology presents a yearly report on the data collected for the national registry. This information shows how procedures are distributed throughout Spain and makes comparisons with other countries feasible. METHODS Institutions provided their data voluntarily (online) and were analyzed by the Working Group's Steering Committee. RESULTS Data were provided by 108 hospitals (72 public and 36 private) that mainly treat adults, Covering 138,480 diagnostic procedures, 123,746 of which were coronary angiograms, slightly more than the year before, with a rate of 3008 coronary angiograms per million population. Percutaneous coronary interventions decreased slightly to 63,202 procedures with a rate of 1373 interventions per million population. Of the 94,701 stents implanted, 61% were drug-eluting stents. In the acute phase of myocardial infarction, 15,491 coronary interventions were performed, 9.4% more than in 2010, representing 24.6% of the total number of coronary interventions. The most frequent intervention for adult congenital heart disease was atrial septal defect closure (298 procedures). Percutaneous mitral valvuloplasty continued to decrease (286 procedures) and percutaneous aortic valve implantations increased, but at a slower pace than in the previous year, with 770 units implanted in 2011. CONCLUSIONS The greatest increase in activity has occurred in the field of myocardial infarction and percutaneous aortic valve implantation. The number of other procedures, both diagnostic and therapeutic, remained stable.
