title: Aortic valve replacement combined with endoventricular circulatory patch plasty (Dor operation) in a patient with aortic valve stenosis and severe ischemic cardiomyopathy.
abstract: A 58-year-old woman with ischemic cardiomyopathy and aortic valve stenosis, underwent aortic valve replacement and simultaneous endoventricular circulatory patch plasty (Dor operation). She underwent coronary artery bypass grafting for severe triple vessel disease 10 years ago. Recently she started to show severe congestive heart failure. Aortic valve stenosis with pressure gradient of 85-mmHg was also found. Coronary bypasses were all patent, but the left ventricle (LV) was severely dilated (LVDd/Ds=71/61 mm) and the ischemic cardiomyopathy was considered as the cause. She successfully underwent aortic valve replacement and endoventricular circulatory patch plasty. The initial postoperative course was complicated with intractable ventricular arrhythmia, but subsequent course was smooth and the patient was discharged with improved symptoms (NYHA Class II). Postoperative catheterization showed decreased left ventricular volume and improved contractility. This case implies the role of LV remodeling procedure in the ischemic cardiomyopathy combined with aortic valve lesion
