The term “bad viscera” is a generalization, which requires a complete preoperative examination and a comprehensive assessment of surgical risk before deciding whether mitral valve surgery can be tolerated.
Mitral valve lesions: Common mitral valve lesions include mitral stenosis, mitral valve closure insufficiency, mitral valve prolapse syndrome, and mitral atresia insufficiency. Different lesions have different treatment options. For patients with particularly severe conditions, and for patients whose clinical symptoms do not improve significantly after particularly conservative treatment, surgical treatment is available.
Preoperative evaluation is required if the patient has abnormal liver, kidney, or lung organ function. If the patient’s basic condition is good and organ dysfunction will not affect the safety of surgery, mitral valve surgical operation can be performed. If the organ dysfunction is obvious and surgery is not possible for the time being, conditioning treatment can be carried out first. When the patient reaches the surgical conditions, then active surgery.
