[Chronic occlusions in patients with coronary heart disease: results of recanalization].

The paper analyzes the results of endovascular treatment in 298 patients with chronic occlusions or subtotal stenoses of coronary arteries. The authors show that balloon coronary angioplasty for chronic coronary occlusions is an effective and relatively safe techniques of myocardial revascularization. Successful endovascularization has been achieved in 68.

[Outcomes of balloon coronary angioplasty of bifurcation stenoses in patients with ischemic heart disease].

The study included 322 patients with bifurcation lesion of the coronary bed who had angioplasty by the conventional procedure by employing one balloon. The authors analyze whether there is a correlation of balloon coronary angiographic findings with the following X-ray morphological characteristics: the origin of a lateral branch from the stenotic segment of the coronary artery, that of the branch at a distance of no more than 10 mm proximal or distal to stenosis, the angle of branch origin. Based on the findings, it was concluded that the origin of the branch from the stenotic segment is a factor that limits an angiographic success of dilatation of the great coronary vessel.

[A comparative analysis of the immediate and late results of coronary balloon angioplasty in bifurcation stenoses performed by the traditional method and by the "2-guide" method].

To evaluate the efficiency of balloon coronary angioplasty (BCA) for bifurcation stenoses, which had been made by the two-guide method, the results of the angioplasties were examined in 147 patients with coronary heart disease. BCA had been performed routinely in 54 patients and by the two-guide method in 32. Sixty-one patients undergone angioplasty for nonbifurcation lesions served as a control group.
