Brief Summary:

MES-HT is a pilot multicenter prospective study conducted in transplant patients who developed severe coronary vasculopathy. A preparation of autologous mesenchymal cells of bone marrow is administered by endomyocardial injection, guided by the Noga® cardiac mapping system.

The main objective is to determine the effect of the administration of autologous mesenchymal cells of the bone marrow by intramyocardial injection on myocardial perfusion in cardiac transplant patients with severe coronary vasculopathy.

Arm Intervention/treatment
Experimental: Mesenchymal cell therapy Biological: Mesenchymal cell therapy

Name of the experimental cell preparation: Concentrated mesenchymal stem cells (MSCs) derived from autologous bone marrow

  • Registry Type: autologous
  • Qualitative and quantitative composition of the finished product: The product is a cell suspension consisting of mesenchymal stem cells (MSC) 40 x 106 MSC / ml suspended in human albumin (ALBUNORM ® 5% OCTAPHARMA France).
  • Route of administration: endomyocardial injection
  • Dose administered: 120-140 x106 MSC (mesenchymal stem cells)
