[Surgery for Ventricular Tachycardia Arising from Left Ventricular Aneurysm in a Patient with Dilated Cardiomyopathy；Report of a Case].

A left ventricular aneurysm (LVA) generally results from myocardial infarction, but rarely LVA can be associated with dilated cardiomyopathy (DCM). We herein report a surgical case of malignant ventricular tachycardia (VT) in a patient with LVA associated with DCM. A 57-year-old woman was diagnosed with DCM and LVA when she 1st presented with sustained VT. She had anti-arrhythmic medical therapy and implantable cardiac defibrillator. Subsequently, she presented with recurrent monomorophic VT arising from the LVA. Because anti-arrhythmic medical therapy and endocardial ablation were not effective, the patient was performed left ventricular aneurysmectomy and encircling endocardial cryoablation and could achive good arrhythmic control and clinical outcome.
