Rationale and design of the Concordance study between FFR and iFR for the assessment of lesions in the left main coronary artery. The ILITRO-EPIC-07 Trial

REC: Interventional Cardiology (English Ed.), 2022
Introduction and objectives: Patients with left main coronary artery (LMCA) stenosis have been excluded from the trials that support the non-inferiority of the instantaneous wave-free ratio (iFR) compared to the fractional flow reserve (FFR) in the ...

Impact of Age on the Functional Evaluation of Intermediate Coronary Stenoses With Instantaneous Wave-Free Ratio and Fractional Flow Reserve

, 2021
The optimal strategy for assessing the ischemic significance of intermediate coronary stenoses with adenosine-induced fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) is still debated.

Physiologic evaluation of coronary lesions using instantaneous wave-free ratio (iFR) in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation [PDF]

EuroIntervention, 2018
We sought to assess eventual changes in iFR measurements in patients with aortic stenosis (AS) before and after TAVI in coronary lesions with different degrees of angiographic severity.The functional relevance of 145 coronary lesions was assessed by online iFR and FFR measurement in 66 patients with severe AS before and after TAVI, during the same ...

Utility of the pressure guidewire in diabetic patients

REC: Interventional Cardiology (English Ed.), 2022
Blood pressure indices like fractional flow reserve (FFR) and the instantaneous wave-free ratio (iFR) measure the distal-to-aortic pressure ratio of a lesion in a similar way using a pressure guidewire.

Waves and Windkessels reviewed

Artery Research, 2017
Pressure and flow are travelling waves and are reflected at many locations. The forward and reflected waves, obtained by wave separation, are compound waves.

STABILITY OF THE DIASTOLIC WAVE-FREE PERIOD AFTER PHARAMOCOLOGICAL PROVOCATION, AND DURING HAEMODYNAMIC PERTURBATIONS: IMPLICATIONS FOR THE CLINICAL APPLICABILITY OF THE INSTANTANEOUS WAVE-FREE RATIO (IFR)

Journal of the American College of Cardiology, 2012
The instantaneous wave-free ratio (iFR) is a new pressure-only adenosine independent intra-coronary index of coronary stenosis severity comparable to fractional flow reserve (FFR). It is measured during a naturally occurring diastolic wave-free period.
