Who could benefit from this research

Could help

Ideal candidates would be people who have had a myocardial infarction and who have scar‑related ventricular tachycardia or are judged at high risk for VT due to infarct borderzone scarring.

Less likely to help

Patients without post‑MI scar‑related ventricular arrhythmias, with primary electrical disorders unrelated to infarct scarring, or who are not eligible for epicardial interventions may not benefit from this approach.

What this research studies

This project develops a gene-based approach delivered to the outer surface of the heart using adeno-associated virus (AAV) vectors to change electrical behavior in scarred heart tissue. The team targets proteins (KCNE3 and KCNE4) that create uneven recovery of heart cells and also tests genes that can slow or speed conduction to interrupt the abnormal circuits that cause ventricular tachycardia. Researchers use laboratory and animal models and specialized epicardial 'gene painting' techniques to achieve full‑thickness delivery to the damaged region of the heart. The goal is to translate those preclinical results into a therapy that could one day be offered to people after a heart attack who are at risk for scar‑related VT.

Why it matters

Potential benefit: If successful, this approach could reduce or eliminate deadly ventricular tachycardia and lower the risk of sudden cardiac death after a heart attack.

How similar studies have gone: Related gene‑transfer approaches have shown promise in preclinical (animal and lab) studies, but human applications for preventing scar‑related VT remain experimental and novel.
