Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to evaluate the safety and efficacy of allogeneic induced pluripotent cell derived cardiomyocytes (iPSC-CMs) in treating patients with worsening ischemic heart failure undergoing coronary artery bypass graft surgery.

After screening, iPSC-CMs will be administrated intramyocardially in consented and eligible patients undergoing open-chest CABG surgery and the estimated population size for the study will be 32 patients.
