Mitral valve surgery includes mitral valve repair and mitral valve replacement repair. The life expectancy after mitral valve surgery is directly related to the patient's preoperative heart function. Patients with poor heart function or poor physical condition have worse prognoses after surgery. If the preoperative heart function and cardiac quality are good and the surgery is timely, the prognosis can be good, even reaching normal life expectancy. Conversely, if the preoperative heart function is poor and the overall physical condition is not good, the prognosis tends to be worse due to the patient's physical state. In general, the earlier the detection and the more timely the surgery, the better the prognosis. Therefore, if there is any growth, it is necessary to seek medical attention promptly.
