Valve replacement surgery can be further categorized into surgical and minimally invasive surgery, with surgical surgery being the larger procedure and minimally invasive surgery being relatively less invasive but more demanding on the physician’s level. Conventional open heart surgery valve replacement requires cutting open the sternum and heart under general anesthesia, as well as establishing cardiac arrest and extracorporeal circulation. The procedure is risky and complex, and is therefore one of the major surgical procedures. Although transcatheter valve replacement is a minimally invasive procedure, the patient should be fully evaluated before valve replacement, and preoperative blood tests, blood biochemistry, electrocardiogram, and cardiac ultrasound should be performed. Valve replacement should not be performed if there are coagulation disorders, low platelet counts, or severe liver, kidney, or cardiac impairment. After the operation, you need to follow the doctor’s instructions to take warfarin anticoagulation; closely observe your vital signs, and inform the doctor in time if there is any abnormality, and follow the doctor’s instructions for treatment.
