[Peculiarities of endovascular myocardial revascularization in patients with coronary heart disease and multivascular lesions in the coronary bed].

This study included 171 patients with multivascular lesions in the coronary bed treated endovascularly for myocardial revascularization. The patients divided into 3 groups underwent complete, functionally adequate, and incomplete revascularization respectively. Analysis of clinical, anamnestic and angiographic characteristics of the patients revealed possible risk factors hampering the necessary extent of revascularization in case of multivascular lesions in the coronary bed such as chronic coronary occlusion, occlusion of more than 20 mm of the coronary artery, high risk of percutaneous coronary intervention based on the SYNTAX Score scale, and calcinosis of the effected segment.
