In 1979, the first transluminal coronary angioplasty (PTCA) was performed in Brazil, two years after the original contribution of Andreas Gruentzig, in Zurich. In the years which followed, the development of PTCA in the country grew and in the mid eighties several centres had already had the experience of more than 600 cases. In the beginning of the nineties, PTCA underwent an additional promotion with a large number of procedures, now subventioned by the bodies of public health. In addition to this, the introduction of new technologies such as directional atherectomy, rotablator, laser and stents. In 1991, the Brazilian Society of Interventional Cardiology created a national registry (CENIC) to gather data on the coronary procedures performed in the country. The CENIC data for the 1992/1993 and 1996/1997 bienniums were compared and it was observed that there had been a significant increase in the number of cases treated (from 16,429 in 92/93 to 22,025 in 96/97), complex lesions of the B/C type (from 71.4% to 92.3%), patients with previous revascularisation (from 22% to 28.3%), acute myocardial infarction (from 16% to 17.4%) and multiarterial lesions (from 34.4% to 38.8%). However, despite a greater clinical and angiographic complexity, the success of the procedure grew (from 89.7% to 92.8%) and complications reduced: acute occlusion (from 3.2% to 1.5%); acute myocardial infarction (from 2.5% to 1.2%) and death (from 1.8% to 1.4%). Interventional cardiology in Brazil has consequently progressed at the same rate as that of other countries. The incorporation of new technologies, particularly coronary endoprostheses has increased, guaranteeing better success rates, better results and a decrease in complications arising from acute occlusion of the target vessel.
