Spanish Cardiac Catheterization and Coronary Intervention Registry. 26th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Catheterization and Interventional Cardiology (1990-2016).

INTRODUCTION AND OBJECTIVES: The Working Group on Cardiac Catheterization and Interventional Cardiology presents its annual report on the activity data for 2016.

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

RESULTS: In 2016, 106 centers participated in the national registry; 80 of these centers are public. A total of 154 362 diagnostic studies were carried out, of which 135 332 were coronary angiograms. These figures are 14% higher than in previous years. The Spanish average of total diagnostic procedures per million population was 3322 (3.127 in 2015). The number of coronary interventional procedures was 7% higher than in the previous year: 68 695 (67 671 in 2015) and, although multivessel treatment decreased by 3%, unprotected left main trunk treatment increased by 9.4%. A total of 104 628 stents were implanted, of which 88 344 (84.4%) were drug-eluting stents (10% higher than in 2015) and 1610 were bioresorbable scaffolds. A total of 20 588 interventional procedures were performed in the acute myocardial infarction setting (10% increase), of which 83.7% were primary angioplasties. The radial approach was used in 74.2% of the diagnostic procedures, similar to the previous year, and in 82.6% of interventional procedures (7% increase). The number of transcatheter aortic valve implantations continued to increase (28% increase, n = 2026), as did the number of percutaneous mitral valve repair procedures (MitraClip) (45% increase, n = 232) and left atrial appendage closures (48.5% increase, n = 496).

CONCLUSIONS: The number of diagnostic and therapeutic procedures in acute myocardial infarction increased in 2016. The use of the radial approach and drug-eluting stents also increased in therapeutic procedures. The growing trend observed in previous years continued for the use of transcatheter aortic prosthesis, the MitraClip device, and left atrial appendage closure.
