Aortic stenosis test for open heart surgery is inaccurate
An approved exercise test that determines whether people with aortic stenosis need open heart surgery has only 60% accuracy, according to a new study by the University of Leicester.
Cycling on a stationary bike typically determines whether a person needs surgery. If the patient becomes breathless while cycling, it is typically recommended to have valve replacement therapy.
Approximately 10,000 aortic valve replacements are done a year and have a cost of up to £15,000. It takes anywhere between 7 and 10 days for a patient to recover after valve replacement surgery.
