Marfan surgery is a procedure performed on a patient with Marfan syndrome. The number of years it lasts after surgery depends largely on the current status of the patient; if the patient is younger and in stronger health, it can last up to 5 to 6 years, but if he or she is in poorer health, it may only last for 2 to 3 months. If the patient is younger and in better physical condition, and successfully passes the surgery for heart valve repair or vascular replacement without abnormal surgical complications and has a better recovery, he/she can maintain up to 5 to 6 years. However, if the patient’s basic condition is poor, and there are serious complications after surgery such as hemangioma, pericardial tamponade, it may lead to heart failure due to acute myocardial ischemia, infarction, etc., and even life-threatening, and at this time, it may only be for 2 to 3 months. Marfan should pay attention to care after surgery, if abnormalities occur, you should seek medical treatment.
