Background-We aimed to test, for the first time, the feasibility of intracoronary delivery of an innovative, injectable bioabsorbable scaffold (IK-5001), to prevent or reverse adverse left ventricular remodeling and dysfunction in patients after ST-segment-elevation myocardial infarction. Methods and Results-Patients (n=27) with moderate-to-large ST-segment-elevation myocardial infarctions, after successful revascularization, were enrolled. Two milliliters of IK-5001, a solution of 1% sodium alginate plus 0.3% calcium gluconate, was administered by selective injection through the infarct-related coronary artery within 7 days after myocardial infarction. IK-5001 is assumed to permeate the infarcted tissue, cross-linking into a hydrogel and forming a bioabsorbable cardiac scaffold. Coronary angiography, 3 minutes after injection, confirmed that the injection did not impair coronary flow and myocardial perfusion. Furthermore, IK-5001 deployment was not associated with additional myocardial injury or re-elevation of cardiac biomarkers. Clinical assessments, echocardiographic studies, 12-lead electrocardiograms, 24-hour Holter monitoring, blood tests, and completion of Minnesota Living with Heart Failure Questionnaires were repeated during follow-up visits at 30, 90, and 180 days after treatment. During a 6-month follow-up, these tests confirmed favorable tolerability of the procedure, without device-related adverse events, serious arrhythmias, blood test abnormalities, or death. Serial echocardiographic studies showed preservation of left ventricular indices and left ventricular ejection fraction. Conclusions-This first-in-man pilot study shows that intracoronary deployment of an IK-5001 scaffold is feasible and well tolerated. Our results have promoted the initiation of a multicenter, randomized controlled trial to confirm the safety and efficacy of this new approach in high-risk patients after ST-segment-elevation myocardial infarction.
