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.
