However, it is difficult to argue in favor of an approach that requires a diagnostic cardiac catheterization for patients who might not have needed one had they had a negative noninvasive test. Furthermore, FFR is an invasive procedure that carries small but significant additional risks beyond those associated with diagnostic coronary angiography, and the technology is available only in a minority of US catheterization laboratories. Finally, noninvasive testing with selective cardiac catheterization has been shown to be more cost-effective than routine cardiac catheterization for patients with stable coronary artery disease,2 so there are likely few situations where routine cardiac catheterization plus FFR would be more cost-effective than a strategy of initial stress testing.
