The cost of aortic valve replacement surgery is usually controlled between 60,000 and 80,000 RMB. It varies from patient to patient because different patients have different physical and cardiac functional status, and the presence or absence of comorbidities also determines the cost of the surgery. 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 60,000-80,000 RMB, but the heart’s function needs to be adjusted before the surgery, which requires costs. In addition, the length of the surgery, the time spent in the care unit after the surgery, and the need for frequent laboratory tests to adjust the dosage of warfarin after the surgery will also increase the cost of the surgery. For different patients with different cardiac function status, some may stay in the hospital for a longer period of time after the operation, and the hospitalization cost of this type of patients will also increase. In addition, after discharge from the hospital, follow-up treatment costs, for example, if the replacement of mechanical valve, the patient needs to be lifelong anticoagulation, every three months or even every month to the hospital to test the coagulation function, to adjust the dose of warfarin, which will also incur costs. Regular follow-ups with cardiac ultrasound and electrocardiograms to evaluate the recovery of heart function are often not insignificant in the long run. So the overall cost of aortic valve replacement surgery during hospitalization is roughly RMB 60,000 to 80,000, but this can vary depending on the individual’s specific situation.
