[Repeat percutaneous transluminal angioplasty in coronary artery restenosis].

Early experience with repeat transcutaneous transluminal coronary angioplasty (TTCA) in 9 coronary patients is reviewed. The interval between the first and the repeat TTCA varied between 1 and 12 months averaging 4.9 +/- 4.

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

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.

[Use of percutaneous transluminal coronary angioplasty in treating acute myocardial infarct patients].

Transcutaneous transluminal coronary angioplastics was performed in 8 patients with acute myocardial infarction. In five patients dilatation of the coronary artery was carried out after intracoronary thrombolytic therapy and in the 3 others without the preliminary infusion of streptokinase. The method proved effective in 6 out of the 8 patients: the diameter of stenosis of the coronary artery decreased on the average from 70.

[Effectiveness of treatment of patients with acute myocardial infarction by intracoronary administration of nitroglycerin and streptokinase].

The intracoronary administration of nitroglycerin and streptokinase was assigned to 95 patients with acute myocardial infarction. In 69 (79.3%) out of the 87 occluded coronary arteries the antegrade blood flow was restored.

[Selective thrombolytic patency of the coronary arteries in patients with acute myocardial infarction].

Urgent selective coronarography followed by intracoronary infusion of nitroglycerin and streptokinase (2000-4000 U/min) was performed in 24 patients with acute myocardial infarction. Mechanical recanalization of an occluded coronary artery was also performed in two patients. The coronary artery supplying the infarcted area was occluded in 22 patients while 2 patients had third-degree stenosis.
