The cost of aortic valve replacement surgery is generally controlled at roughly 60-80,000 RMB. It also varies for different patients because the physical status and functional status of the heart varies from patient to patient, and the presence of comorbidities also determines the cost of the procedure. For example, if it is just rheumatic heart valve disease and the aortic valve is diseased and needs to be replaced with a mechanical valve, the cost of the surgery is about 60-80,000 RMB, but the heart needs to be adjusted before surgery, which costs money. In addition, the length of the operation, the time spent in the monitoring room after the operation, and the frequent laboratory tests to adjust the dosage of warfarin drugs just after the operation will also increase the cost of the operation. For different patients with different cardiac function status, some may stay in the hospital for a longer period of time after surgery, which may also increase the cost of hospitalization for this type of patients. For example, if a mechanical valve is replaced, the patient will need lifelong anticoagulation and will have to come to the hospital every 3 months or even every month for coagulation tests and warfarin dose adjustment, which will also incur costs. Regular follow-ups with cardiac ultrasound and electrocardiograms to evaluate the recovery of heart function are often costly in the long run as well. Therefore, the overall cost of aortic valve replacement surgery during hospitalization is roughly 60,000-80,000 RMB, but this may vary depending on the specific condition of each individual.
