The indication for aortic valve replacement (AVR) combined left ventricular (LV) plasty in the patient with aortic valve stenosis (AS) complicated by ischemic heart disease is controversial. We describe a case of AS with ischemic heart disease of a patient who underwent a successful surgical treatment, AVR combined with the endoventricular patch technique. The patient was an 82-year-old woman who suffered from heart failure, New York Heart Association (NYHA) class III. The heart failure derived from AS and ischemic heart disease with severely compromised LV function. She underwent AVR combined with the endoventricular patch technique and the postoperative course was uneventful. She has been well with NYHA class I for about 5 years after the operation without heart failure.
