Background: Less Invasive Ventricular Enhancement (LIVE) with Revivent TC is an innovative therapy for symptomatic ischemic heart failure (HF). It is designed to reconstruct a negatively remodeled left ventricle (LV) after an anterior myocardial infarction (MI) by plication of the scar tissue. Its indications are specific, and as with any other structural heart intervention, the success of the procedure starts with appropriate patient selection.

The aim of the study was to describe long-term effect of minimally invasive hybrid transcatheter and minithoracotomy left ventricular (LV) reconstruction in patients with ischemic cardiomyopathy. Twenty-three subjects with transmural anterior wall scarring, LV ejection fraction 15-45%, and New York Heart Association class ≥ II were intervened using Revivent TC anchoring system.

The resultant increased left ventricular systolic volume and discrete, contiguous, noncontractile (akinetic and/or dyskinetic) scar located in the anteroseptal, apical (may extend laterally) region of the left ventricle (LV) lends itself to Revivent.

The BioVentrix Revivent TC System offers efficacy comparable to conventional surgical ventricular reconstruction and is less invasive utilizing micro-anchor pairs to exclude scarred myocardium on the beating heart. Here, we present 12-months follow-up data of an international multicenter study.

Methods And Results: Myocardial infarction (MI) was induced by coil occlusion of the middle left anterior descending artery and diagonals. Two months after MI creation, TCVR was performed via a minimal thoracotomy in eight sheep.
Objective: The loss of normal apical rotation is associated with left ventricular (LV) remodeling and systolic dysfunction in patients with congestive heart failure after myocardial infarction. The objective of the present study was to evaluate the effect of epicardial ventricular reconstruction, an off-pump, less-invasive surgical reshaping technique, on myocardial strain, LV twist, and the potential alteration of myocardial fiber orientation in an ovine model of LV anteroapical aneurysm.
Methods: LV anteroapical myocardial infarction was induced by coil embolization of the left anterior descending artery.
Objectives: Surgical ventricular reconstruction has been used to treat ischaemic cardiomyopathy with large akinetic or dyskinetic areas. However, application of this approach requires a sternotomy, cardiopulmonary bypass and a left ventriculotomy. This study assessed the feasibility and efficacy of minimally invasive, off-pump, epicardial catheter-based ventricular reconstruction (ECVR) in an anteroapical aneurysm ovine model.

Objectives: We previously presented early results employing a technique designed for beating heart, ventricular volume reduction (surgical ventricular restoration, SVR) without ventriculotomy for patients with antero-septal scar and dilated ischaemic cardiomyopathy. Significant volume reduction and clinical improvement were achieved. We now report durability in the first 11 patients available for assessment at 6 and 12 months after operation.

Methods: We analyzed 248 consecutive patients who underwent surgical ventricular reconstruction at a single center. There were 14 perioperative deaths (5.
