title: [Angioplasty in native coronary circulation in patients treated with myocardial revascularization].
abstract: OBJECTIVE
  To evaluate the clinical results after angioplasty in the native coronary vessels in patients who had undergone previous coronary artery surgery.
  
  
  METHODS
  From June 1987 to July 1990, 69 patients with previous coronary artery surgery underwent coronary angioplasty in the native arteries. Age ranged from 31 to 82 (mean = 57.5) years, fifty eight were males. Angina was present in all patients. The patients were classified in three groups according to the following criteria: group I--incomplete revascularization following bypass surgery (28 patients); group II--progression of the disease in ungrafted vessels (24 patients) and group III--progression of the disease in grafted vessels (17 patients).
  
  
  RESULTS
  Primary success was achieved in 94% (65/69). Ninety-five percent in group I, 92% in group II and 94% in group III. Complications occurred in 4%; emergency surgery or deaths were not observed in this study. Forty patients (61%) repeated coronary arteriography an average follow-up of 4 months and restenosis was detected in 10 (25%); 8 of them were redilated. Survival rates was 95% and 75% of them were free of coronary events after an average follow-up of 13 months.
  
  
  CONCLUSIONS
  Coronary angioplasty in these patients is a safe and effective interventional procedure in the treatment of coronary artery disease in native coronary vessels.
