Abstract
Introduction. One of the most difficult and completely unsolved problems of modern interventional cardiology is bifurcation stenting of the coronary arteries. This problem requires a comprehensive study, including using the possibility of morphological analysis.
Material and methods. Stenting of the bifurcation lesions of the coronary arteries on 46 cadaveric hearts was performed using the bifurcation and conventional stents with subsequent plating and study of the preparations obtained.
Results. From the point of view of the safety of the lateral branch, T-stenting is optimal, especially when implanting a BIOSS stent. When using the Tryton stent with the culotte stenting technique, there was never a stenosis of the side branch, due to the stent in the lumen, but there was always an excessive metal saturation in the main branch before the bifurcation. When using conventional stent with a provisional T-stenting technique residual, stenosis of the mouth of the lateral branch was also observed. In addition, in all cases there was a deformation of the stent beams near the mouth of the lateral branch.
Conclusions. Morphological studies of stented coronary arteries on anatomical preparations of the heart, plastized with epoxy resin, make it possible to obtain new results that cannot be obtained with traditional morphological and clinical research methods (histological, corrosive, radiological, etc.).
