Brief summary
The purpose of this trial is to evaluate the efficacy of a pericardial adipose graft transposition (Adipose Graft Trasposition Procedure, AGTP) for the improvement of cardiac function in patients with a chronic myocardial infarction. Preclinical studies in the porcine model of myocardial infarction have shown that the AGTP reduces infarct area and improves cardiac function. A first-in-man clinical (NCT01473433) trial showed that the AGTP is safe in patients.
Interventions
Patients with a myocardial necrosis candidates for revascularization of other myocardial areas, will be enrolled. The non-revascularizable area will be covered with the adipose graft and the revascularizable area will be treated with the normal procedure (by-pass).
Patients with a myocardial necrosis, candidates for revascularization of other myocardial areas, will be enrolled. The non-revascularizable area will be left untouched and the revascularizable area will be treated normally (by-pass).
