 A 61-year-old Japanese man, who complained of chest oppression and dyspnea was admitted to our institution. Cardiac Echocardiography and catheterization confirmed the presence of severe ischemic dilated cardiomyopathy with coronary artery aneurysms(left ventricular[LV]ejection fraction 12%, LV diastolic dimension 81mm, LV systolic dimension 75mm, atrial fibrillation and complete left bundle branch block). We applied coronary artery bypass grafting and Dor's endoventricular circular patch plasty, and cardiac resynchronization therapy with an implantable cardioverter-defibrillator(CRTD)to the patient. An epicardial LV lead was surgically implanted on the posterolateral wall. CRTD achieved the resynchronization of the LV contraction, and improved cardiac function. The patient had an uneventful postoperative course and was discharged from hospital 21 days after his operation.

 The clinical course of this case indicates that left ventricular volume reduction surgery in combination with implantation of CRTD might be effective for patients with end-stage ischemiccardiomyopathy.
