The majority of ventricular tachycardias (VTs) occurs in patients with structural heart disease and is associated with an increased risk of sudden cardiac death. These VT are scar-related and may develop in patients with ischaemic or non-ischaemic cardiomyopathies.

Authors describe a 44-year-old patient without any pre-existing cardiovascular disease, presenting with the first documentation of a haemodynamically unstable sustained fast VT with a cycle length of 250 ms. He reported a suicidal attempt with a self-made handgun aged 16 when he had shot himself in the thorax and had injured the myocardium. After presenting with the VT coronary artery disease was excluded through cardiac catheterization.

A cardiovascular magnetic resonance study showed a localized myocardial scar in the left ventricular free wall starting from the subepicardium and correlating to the scar described 28 years ago by the thoracic surgeons. In an electrophysiological study, non-sustained VT were easily inducible. Presuming a causal relationship between the fast VT and the epicardial scar, a single-chamber implantable cardioverter-defibrillator was implanted and beta-blocker therapy was initiated.

Scar-related VT often occur many years after an acute event, e.g. an acute myocardial infarction. This case highlights, that any cardiac trauma, even a superficial epicardial projectile-related damage with subsequent scarring, may cause a VT after many years and to the knowledge for the first time describes the occurrence of a VT due to mechanical damage to the myocardium by a gunshot.
