Abstract
The mechanism by which transmyocardial revascularization (TMR) offers clinical benefit is controversial. We hypothesized that TMR ameliorates vasoconstriction in patients with ENDCAD
Highlights
Aims/Objectives This study was undertaken to demonstrate that transmyocardial laser revascularization in patients with advanced CAD improves results of combined operations CABG+ transmyocardial revascularization (TMR) through reduction of vasoconstriction
We investigated vessels of coronary microvascular network of patients with ENDCAD and analyzed the histological changes in two groups: in group of patients died after sole CABG (1-st group - 8 heart specimens) and group of patients died after combined operations CABG+TMR (2-nd group - 6 heart specimens).These data are compared with hospital results in two large groups of patients with ENDCAD: with isolated CABG (1-st group -33 operations) and CABG+TMR (2-nd group - 87 operations), operated in 2011-2012
High indices of hospital mortality (12.1%) and morbidity(33.3%) in cases with sole CABG can be explained with coronary spasm in patients with advanced CAD
