The results of the Spanish Registry of Hemodynamic and Interventional Cardi
ology of the Spanish Society of Cardiology in 1998 are hereby presented. Th
e Registry collects the activity of 82 centers, which constitutes all the c
ardiac catheterization laboratories in Spain. The main activity was adult c
ardiac catheterization in 75 centers, and exclusively pediatric cardiac cat
heterization in 7.
A total of 74,364 diagnostic catheterization procedures, 80% coronary angio
graphies (59,321; 1,498 per million inhabitants), were performed, which rep
resents a 2.8% total increase compared to 1997.
Coronary intervention increased by 8.6% compared to 1997, for a total numbe
r of 20,146 procedures. The ratio of coronary interventions per million inh
abitants was 509. Success rates of coronary interventions (94%) and complic
ations (2.3%) are similar to those registered in previous years, and in 9.7
% of the cases, IIb-IIIa glicoprotein inhibitors were used. A 8.6% of the p
rocedures were performed in order to treat an acute myocardial infarction.
Coronary stenting is, continues to be the main device for coronary interven
tion. In 1998, coronary stents were employed in 14,497 cases (a 27% increas
e compared to 1997) which represents the 72% of all coronary revascularizat
ions procedures. A total of 19,378 prosthesis were implanted, 83% in a elec
tive way and 12.9% primary stenting, with a low rate of complications (1.5%
subacute closure, 1.5% myocardial infarction and 0.94% mortality).
Compared to 1997, directional coronary atherectomy (83 procedures) showed a
slight decrease, whereas rotational atherectomy (549 procedures) has stabi
lized the number of procedures and centers performing this technique.
As in previous years, a slight decrease (9% compared to 1997) in adult valv
uloplasties (505 vs 559) were noted. Pediatric interventional procedures in
creased by 20% (557 vs 465 procedures) compared to the 1997 Registry.
