OBJECTIVE To report the data on the first 2 years (1992-1993) of activity of the National Registry of Cardiovascular Interventions (CENIC) of the Hemodynamic and Angiography Department (DHA) of the Brazilian Society of Cardiology (SBC). METHODS The full members of the DHA of the SBC sent their data on seven types of interventions: balloon angioplasty (PTCA), mitral balloon valvoplasty (MBV), pulmonary balloon valvoplasty (PBV), aortic balloon valvoplasty (ABV), tricuspid balloon valvoplasty (TBV), aortic balloon dilation (AoB) and balloon dilation of pulmonary branches (PBB), to the CENIC. RESULTS Ninety-seven interventional cardiologists and 71 hospitals in 14 states, participated in this data bank. During this time, 16,429 PTCA, 551 MBV, 347 PBV, 62 ABV, 61 AoB, 3 TBV and 3 PBB were registered. PTCA was therefore the most performed procedure (94%); primary success rate was 89.7%. As for the major complications, there were 2.5% acute myocardial infarction; 0.8% emergency bypass surgery and 1.8% death. As for the other interventions, the primary success rate was 92.9% for MBV, 88.5% for PBV, 80.3% for AoB, 72.6% for ABV, 66.7% for TBV with 0.54% deaths for MBV patients and 3.23% for ABV patients. CONCLUSIONS The performance of the interventional cardiology in Brazil reflects the difusion of intervention methods in the main hospitals of the country. The results demonstrate a high efficacy and safety rate, characterizing an excellent performance.
