Who could benefit from this research

Could help

Patients with a history of myocardial infarction who are at risk for VT may be eligible, pending device and safety assessments.

Less likely to help

Individuals without prior infarction or those not at risk for VT may not benefit from this approach.

What this research studies

This project aims to use AAV-based delivery and a catheter-based gene painting approach to normalize heart electrical signals in damaged heart tissue. By targeting specific potassium channel subunits involved in VT circuits, the work hopes to reduce malignant reentrant rhythms. The plan involves phase 1 experiments to finish developing the gene painting catheter and demonstrate safe, effective delivery to the heart tissue. If successful, these methods could lower the risk of VT in patients who have suffered a myocardial infarction.

Why it matters

Potential benefit: If successful, people with prior heart attack could have a lower risk of life-threatening ventricular tachycardia.

How similar studies have gone: Prior work shows feasibility of epicardial gene delivery and catheter-based gene painting, with promising early data in related models.
