Assessment of informative value of myocardial biopsy based on autopsy data from the same cardiac compartments in patients with ischemic cardiomyopathy

This research was conducted to assess the informative value of morphological analysis of myocardium biopsy material in patients with ischemic cardiomyopathy (ICMP). Biopsy and autopsy from both left ventricle (LV) and right atrium (RA) were taken. Microscopy analysis of RA and LV biopsies compared with autopsy material showed that, apart from the changes caused by ICMP and post mortem remodeling, the latter had differences caused by insufficient representativeness of small fragment of the myocardium sampled intra vitam.
