[Results of using percutaneous transluminal coronary angioplasty in patients with stable and unstable angina pectoris and acute myocardial infarct]

Abstract

Transcutaneous transluminal coronary angioplastics (TTCA) was performed in 28 coronary heart disease patients (8 patients had stable and 5 others labile angina, 15 presented acute myocardial infarction, AMI). The patients with AMI received intracoronary thrombolytic treatment prior to TTCA. Successful dilatation was performed in one patient with narrowing of the main trunk of the left coronary artery, in 14 of 21 patients with the stenosis of the anterior interventricular branch and in 5 of 6 patients with the narrowing of the right coronary artery. In three cases TTCA was carried out in the presence of the occluded coronary artery, with two patients benefiting from the operation. In 5 patients with AMI in whom an attempt to dilate the lumen of the coronary artery was unsuccessful, emergency surgery for aorto-coronary shunting was conducted. This operation was also performed in the planned order in 2 angina patients. In 7 patients the failure of TTCA was explained by the impossibility to pass the dilatary sound through the stenosis of the coronary artery and in 1 case by the failure to enter the ostium of the left coronary artery with the guiding catheter.
