Key result
Measurement of trans-stenotic pressure gradient and flow velocity using miniaturized sensors provides an alternative to non-invasive methods for assessing coronary stenosis severity.
Intracoronary measurement of pressure and flow velocity using guidewire sensors provides a functional assessment of stenosis severity, with complex indices improving accuracy for intermediate lesions.

Supports sensor-based functional assessment of intermediate stenoses; hypothesis-generating pending prospective validation versus non-invasive methods.
Mario et al. (1995) conducted a review in Coronary stenosis. Measurement of trans-stenotic pressure gradient and post-stenotic flow velocity vs. Conventional non-invasive methods was evaluated. Measurement of trans-stenotic pressure gradient and flow velocity using miniaturized sensors provides an alternative to non-invasive methods for assessing coronary stenosis severity.
