Prediction of fractional flow reserve using intravascular ultrasound
Authors' conclusion
The IQ-FFR is a promising method to identify coronary lesions requiring revascularisation and to predict the FFR after stent implantation.
Study context
- Population
- Coronary lesions with stenosis (25–99%) and intravascular ultrasound (IVUS) and fractional flow reserve (FFR) measured just before and after stent implantation
- Participants
- 270 coronary lesions
- Comparison
- IVUS-derived IQ-FFR vs wire-derived FFR
- Outcome
- Agreement of IQ-FFR with wire-derived FFR
Methodological detailsprospective, single-centre
- Prospective
- Single-centre
