Brief Summary

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

The purpose of this study is in a phase I/II safety and efficacy study to evaluate the clinical effect of coronary artery bypass graft (CABG) combined pedicled omentum wrapped autologous atrial tissue patch cardiomyoplasty for patients with ischemic cardiomyopathy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a phase I/II, randomized controlled trial to evaluate the use of CABG combined pedicled omentum wrapped autologous atrial tissue patch cardiomyoplasty for patients with ischemic cardiomyopathy. The study hypothesis is that the combined surgical technique to perform pedicled omentum wrapped autologous atrial tissue patch cardiomyoplasty as adjunct to CABG, is safe to patients with severe ischemic heart failure and can improve regional myocardial perfusion contractility, which resulting in improved systolic and diastolic left ventricular function.

The primary object of this study will be to evaluate the safety and efficacy of this novel combined surgical technique. The efficacy will be assessed changes in left ventricular ejection fraction by MRI. The secondary endpoint of the study is to assess the effects of this novel combined surgical technique on cardiac contractile function and functional outcome. The effects will be assessed on the basis of clinical status and imaging rests in 6 month follow-up after enrollment. A maximum of 60 patients between 20 and 70 years will be enrolled in the study. These participants will be randomized to receive CABG, pedicled omentum graft combined CABG, or pedicled omentum graft autologous atrial tissue patch cardiomyoplasty combined CABG. The objective evaluations will be performed at baseline and during 6 months follow-up.
