Abstract
The surgical treatment of acute aortic dissection in a patient with idiopathic dilated cardiomyopathy is rare. We present a case of a 70-year-old man with a diagnosis of idiopathic dilated cardiomyopathy and a left ventricular ejection fraction of 0.26 on echocardiography, in whom type A acute aortic dissection developed. We performed emergency surgery, consisting of ascending aortic dissection and cardiac tamponade. We then performed ascending aorta replacement, and coronary artery bypass grafting and intra-aortic balloon pumping were necessary due to stenosis of the right coronary ostium. Postoperatively, mediastinitis occurred on postoperative day 13, and therefore the patient needed intensive care for an extended period and was eventually discharged on postoperative day 97.
