Nonsurgical Management of a Post-Traumatic Left Ventricular Septal Aneurysm in a 13-Year-Old Male.

CASE SUMMARY: A 13-year-old previously healthy boy developed a left ventricular septal aneurysm following blunt chest trauma, presenting with electrocardiographic changes and elevated troponin. Echocardiography demonstrated an apical septal aneurysm without ventricular septal defect and with preserved systolic function. Cardiac magnetic resonance imaging revealed near-transmural late gadolinium enhancement. He was managed conservatively with enalapril, propranolol, and aspirin and remained clinically stable with preserved function.

TAKE-HOME MESSAGE: Traumatic left ventricular aneurysms without associated defects and with preserved function may be managed nonsurgically in selected pediatric patients, with multimodal imaging, appropriate medical therapy, and close serial follow-up.
