Summary

This case report details a patient who developed ventricular tachycardia (VT) 28 years after a gunshot wound to the chest caused myocardial scarring. It highlights that cardiac trauma, not just heart disease, can lead to scar-related VT.

Background:

Ventricular tachycardia (VT) is often linked to structural heart disease and carries a risk of sudden cardiac death.
Scar-related VT typically arises in patients with ischemic or non-ischemic cardiomyopathies.

Observation:

A 44-year-old patient presented with hemodynamically unstable fast VT, with no prior cardiovascular disease.
The patient had a history of a gunshot wound to the thorax at age 16, causing myocardial injury.
Cardiac catheterization ruled out coronary artery disease; cardiovascular magnetic resonance revealed a localized myocardial scar correlating with the old injury.

Findings:

Electrophysiological study easily induced non-sustained VT.
A causal link was presumed between the fast VT and the epicardial scar.
A single-chamber implantable cardioverter-defibrillator was implanted, and beta-blocker therapy initiated.

Implications:

This case demonstrates that cardiac trauma, including projectile-related myocardial damage, can cause VT years later.
It underscores that scar-related VT can occur in individuals without traditional risk factors like ischemic heart disease.
This is the first reported case of VT resulting from mechanical myocardial damage due to a gunshot wound.
