Allogeneic Stem Cells Implantation Combined With Coronary Bypass Grafting in Patients With Ischemic Cardiomyopathy
May 3, 2019 updated by: Kyriakos Anastasiadis, AHEPA University Hospital
Study on the Safety and Efficacy of Allogeneic Mesenchymal Stem Cell Implantation Combined With Bypass Grafting in Patients With Coronary Artery Disease and Ischemic Cardiomyopathy.
The aim of the present study is to investigate safety and efficacy of intramyocardial implantation of a novel mesenchymal precursor cell type (iMP) in patients with ischemic cardiomyopathy at the time of coronary artery bypass grafting.

Detailed Description
This study aims to investigates in situ cardiac regeneration utilizing precision delivery of a novel mesenchymal precursor cell type (iMP) during coronary artery bypass surgery (CABG) in patients with ischemic cardiomyopathy (LVEF < 40 %).
Preoperative scintigraphy imaging (SPECT) will be used to identify hibernating myocardium not suitable for conventional myocardial revascularization for iMP implantation.
iMP cells will be implanted intramyocardially in predefined viable peri-infarct areas that show poor perfusion, which could not be grafted due to poor target vessel quality.
Postoperatively, SPECT will be used to identify changes in scar area.
