[Spanish cardiac catheterization and coronary intervention registry. 20th official report of the spanish society of cardiology working group on cardiac catheterization and interventional cardiology (1990-2010)].

INTRODUCTION AND OBJECTIVES The Working Group on Cardiac Catheterization and Interventional Cardiology presents on a yearly basis a report on the data collected for the national registry. This information displays how procedures are distributed throughout Spain and makes comparisons with other countries feasible. METHODS Institutions render their data voluntarily (online) and they are analyzed by the Working Group's steering committee. RESULTS Data was sent by 113 hospitals (71 public and 41 private) that treat mainly adults, reporting 135 486 diagnostic procedures, 119 118 of them coronary angiograms, slightly less than the year before, and with a rate of 2945 coronary angiograms per million inhabitants. Percutaneous coronary interventions increased a bit, to 64331 procedures and a rate of 1398 interventions per million. Of 100371 stents implanted, 61.3% were drug-eluting stents. In the acute phase of myocardial infarction, 14248 coronary interventions were carried out, 6% more than in 2009 and 22% of the total number of coronary interventions. The most frequent intervention for adult congenital heart disease was closure of an atrial septal defect (295 procedures). Percutaneous mitral valvuloplasty continues to decrease (326 procedures) and percutaneous aortic valve implantations are growing rapidly, with 655 units implanted in 2010. CONCLUSIONS The greatest increase in activity has occurred in the field of myocardial infarction and percutaneous aortic valve implantation. The other procedures, both diagnostic and therapeutic, remain stable.
