Cardiac ventricular aneurysms are by and large ischaemic and tend to develop following a transmural myocardial infarction. In the minority of cases, the cause may be congenital, infective, traumatic or idiopathic. While postinfarction ventricular aneurysms and those which follow cardiac surgery are common, traumatic aneurysms after accidental trauma are rare. We report a case of a true left ventricular aneurysm caused by a bullet injury.
