The aim of the study was to compare the efficacy of different techniques of indirect myocardial revascularization: transmyocardial laser revascularization and concomitant injection of mononuclear fraction of red bone marrow in laser canals during surgical treatment of ischemic heart disease. The efficacy was evaluated on the basis of echocardiography and perfusion scintigraphy data obtained in two weeks, 6 months, 12 months and 3 years after operation. Implantation of a mononuclear fraction of red bone marrow into laser canals proved to be the most effective technique. It was confirmed by a significant decrease in angina functional class and a more pronounced increase in myocardial perfusion and contractility.
This literature review focuses on the choice of treatment strategies in patients with aortic stenosis. The main surgical techniques for this condition are presented. The rationale for the efficiency of transcatheter aortic valve implantation is provided. The results of studies comparing the outcomes of surgical and endovascular correction of aortic stenosis are analyzed. Particular attention is paid to the treatment choices in patients with aortic stenosis and a history of coronary artery bypass grafting. Conclusions on the perspectives of transcatheter aortic valve implantation in this cohort of patients are reached.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
