Appendix 17–3. Recommendations for Intracoronary Physiologic Measurements (Doppler Ultrasound, FFR)



Class INone
Class II aLevel of Evidence
1. Assessment of the physiologic effects of intermediate coronary stenosis (30 to 70 percent luminal narrowing) in patients with anginal symptoms. Coronary pressure or Doppler velocimetry may also be useful as an alternative to performing noninvasive functional testing (e.g., when the functional study is absent or ambiguous) to determine whether an intervention is warranted.B
Class II b
1. Evaluation of the success of percutaneous coronary revascularization in restoring flow reserve and to predict the risk of restenosisC
2. Evaluation of patients with anginal symptoms without an apparent angiographic culprit lesionC
