The present invention discloses a valved conduit, which comprises an artificial blood vessel and an artificial valve. The artificial valve is located at the proximal end of said artificial blood vessel. The lateral wall of the artificial blood vessel is provided with left and right openings at positions close to said artificial valve. The positions of said left and right openings correspond to the ostia of the left and right coronary arteries. The valved conduit also comprises a hard tube which is connected with said artificial blood vessel. The hard tube is bound with the aorta through a ligature and a space is formed between the ligation position and the aortic valve. Thereby it is unnecessary to suture the openings and the coronary arteries and reducing the probability of hemorrhage at the anastomotic site.
