Abstract: Disclosed herein is a stent graft for ascending aorta, comprising a stent; a cover attachment at least partially covering the stent; a valve leaflet for reconstructing aortic valves, which are positioned at the proximal end of the stent and attached to the cover attachment and the stent. The valve leaflet for reconstructing aortic valves is configured to allow blood to flow from the left ventricle to the aorta and prevent blood from flowing from the aorta back to the left ventricle. In addition, the stent graft has two windows aligning with two openings of the coronary artery. Therefore, for the aortic root diseases involving aortic sinus and aortic valves, the stent graft for ascending aorta can be implanted into ascending aortic root by minimally invasive endovascular surgery to repair the ascending aorta lesions and reconstruct the aortic valves, aortic sinus, openings of the coronary artery, thereby achieving overall cure.
