Abstract
This study evaluated the safety and feasibility of transendocardial injections of VentriGel, a cardiac extracellular matrix hydrogel, in early and late post-myocardial infarction (MI) patients with left ventricular (LV) dysfunction. VentriGel was delivered in 15 patients with moderate LV dysfunction (25% LV ejection fraction 45%) who were between 60 days to 3 years post-MI and were revascularized by percutaneous coronary intervention. The primary endpoints were incidence of adverse events and abnormal clinical laboratory results. This first-in-man study established the safety and feasibility of delivering VentriGel in post-MI patients, thus warranting further evaluation in larger, randomized clinical trials.
