Dobutamine stress echocardiography is a simple, safe, and readily available method to evaluate prosthetic valve hemodynamics under various flow conditions. A normal response of aortic valve prostheses to dobutamine infusion is a 100% increment in transprosthetic pressure gradients with an unchanged valve area.

D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
