There is a need for a targeted, comprehensive, minimally invasive myocardial restoration treatment aimed at patients with chronic postinfarction heart failure that can provide a sustained effect and be conveniently adopted with transcatheter techniques. Here we evaluated the effectiveness of a platelet-rich plasma hydrogel-based, cell-free therapeutic compound delivered with the aid of a 3-dimensional electromechanical mapping and catheter-based technique (NOGA) in a porcine translational model. We assessed the feasibility of targeted, minimally invasive transcatheter NOGA-guided injections of the therapeutic compound in myocardial infarction (MI) survivors at 8 weeks post-MI. Animals undergoing NOGA-guided hydrogel injections at 8 weeks post-MI demonstrated a significant improvement of the selected left ventricular parameters at a 12-week follow-up. Compared to nonintervention, the hydrogel-based therapy provided significant improvements in end-diastolic volume (−11.0% ± 11.1% vs 6.3% ± 15.2%; P = .008) and ejection fraction (−9.1% ± 16% vs 12.7% ± 18.6%; P = .009). In the slice closest to the apex, significant differences in scar area were observed; the treatment group demonstrated a smaller mean scar area in the infarcted zone compared with the control group (47.1% ± 7.0% vs 59% ± 8.2%; P = .013) and a smaller mean scar area in the border zone compared with the saline group (31.4% ± 8.3% vs 42.6% ± 9.0%; P = .016). The study implies a translational potential of the hydrogel-based therapy and should trigger clinical trials focused on establishing a restoration therapy that can be integrated into a clinical protocol.
