Simultaneous bypass and valve replacement surgery is risky and should be performed at the discretion of the physician. Bypass surgery refers to coronary artery bypass grafting. If the heart valves are diseased and the coronary arteries are severely narrowed, valve replacement and coronary artery bypass grafting can be considered at the same time. After the surgery, the patient should take warfarin and other medications as prescribed by the doctor for anticoagulant therapy and avoid strenuous exercise. However, because the surgery requires general anesthesia and cardiac arrest, it takes longer to perform the surgery at the same time and the risk of performing the surgery at the same time is greater than that of performing the surgery alone, which should be considered after taking into account the condition of the patient, his/her physical condition, and his/her financial condition. Whether or not to undergo two surgeries at the same time should always follow the arrangement of professional doctors, and such surgeries should always be performed in specialized hospitals.
