[Cardiovascular surgery in Spain in 1990. The registry of operations of the Spanish Society of Cardiovascular Surgery].

The Spanish Society of Cardiovascular Surgery has sent a questionnaire to all 37 cardiovascular surgical groups to know the number and type of cardiovascular operations carried out in our country during 1990. The questionnaire was answered by 36 our of 37. In the year 1990, 20.806 cardiovascular patients have been operated upon and 10.065 interventions with extracorporeal circulation have been carried out: 43% in valvular disease, 37% in coronary and 11% in congenital. The number of operations was 5.541 for vascular disease, 4.364 for valvular, 3.917 for coronary, 2.019 for congenital and 4.617 for pacemaker implantation. The number of operations in 1990 is similar to the previous years. There is an increase of about 500 operations under extracorporeal circulation per year in the latest 2 years, mainly due to coronary bypass surgery. The number of vascular operations has slightly been reduced.
