Case report: a giant left ventricular pseudoaneurysm long after blunt chest trauma

Left ventricular pseudoaneurysm is a rare acquired cardiac abnormality that frequently occurs after myocardial infarction or a previous cardiac procedure. Blunt chest trauma accounts for this uncommon entity in sporadic cases. However, this disease does not have any specific clinical findings, so it is necessary to monitor the suspected patient closely. The standard noninvasive techniques for diagnosing left ventricular pseudoaneurysms are transthoracic echocardiography and thoracic computed tomography. Untreated ventricular pseudoaneurysms carry a considerable risk of rupture, ranging from 30% to 45%. So, an urgent surgical treatment is often required. Herein, we aimed to present a 34-year-old male who underwent emergency surgery as a result of cardiac perforation three hours after a traffic accident and developed a giant left ventricular pseudoaneurysm 19 months after discharge. The giant pseudoaneurysm was successfully repaired. This case highlights the need for long‑term surveillance after blunt cardiac trauma to detect late pseudoaneurysm formation.
