That's No Moon, It's a Giant Left Ventricular Aneurysm: A Case Report and Literature Review.

BACKGROUND Although the most common causes of left ventricular aneurysm (LVA) is ischemic disease, other infectious, traumatic, genetic and iatrogenic etiologies exist. With the improvement of medical therapy for ischemic disease and earlier interventions such as PCI, the incidence of large LVA (>3cm) and surgical treatment for it is increasingly rare.  Case study: We describe a case report and literature review of a giant LVA in a patient, who presented with unclear etiology. A 61-year-old male was referred to our tertiary center. He underwent aneurysmectomy and mitral valve replacement for a giant (10cm x 10cm) LVA with severe mitral regurgitation.  Conclusion: Surgery for LVA is becoming less common. Early intervention can restore cardiac geometry with good short and long-term surgical outcomes, especially in patients with preserved EF. Ultimately, a giant ventricular aneurysm remains an indication for surgical intervention. Patients with markedly reduced EF may derive reduced benefits from aneurysmectomy.
