Fractional flow reserve and instantaneous wave-free ratio in coronary artery bypass grafting: a meta-analysis and practice review [PDF]

Frontiers in Cardiovascular Medicine
ObjectiveFractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are invasive methods to assess the functional significance of intermediate severity coronary lesions.

P5617Repeatability of instantaneous wave-free ratio in comparison with fractional flow reserve

European Heart Journal, 2019
Abstract Background Instantaneous wave-free ratio (iFR) has been recently introduced as an adenosine free alternative for fractional flow reserve (FFR) to assess the functional significance of epicardial coronary stenosis.

Instantaneous wave-free ratio to guide coronary revascularisation:Physiological framework, validation and differences from fractional flow reserve

EuroIntervention, 2017
Determining the optimal treatment strategy for revascularisation of coronary artery stenosis involves the use of fractional flow reserve (FFR). To improve the low clinical uptake of physiological lesion assessment to guide revascularisation, the instantaneous wave-free period (iFR) was proposed as a simpler alternative to FFR that does not require ...

Instantaneous Wave-Free Ratio-Guided Interventions in Side Branches Improve Results in Bifurcation Lesions Compared to Conventional Techniques

Journal of Interventional Cardiology
Conclusions: iFR-guided side-branch intervention involving drug-eluting balloon inflation in bifurcation lesions was significantly better when compared to conventional interventions in terms of clinical and functional outcomes in patients with coronary ...

Cardiovascular Outcomes in Patients With Deferred and Performed Coronary Revascularization Based on Intracoronary Physiology: A Systematic Review and Meta‐Analysis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Although large studies and pooled analyses of individual patient data have demonstrated the safety of deferring coronary revascularization based on a nonischemic intracoronary pressure index result, conflicting findings have emerged in ...

Competitive blood flow as a predictor of mammarocoronary artery bypass graft failure: the role of instantaneous wave-free ratio

Вестник хирургии имени И.И. Грекова
The objective was to estimate the impact of competitive blood flow on the development of dysfunction of the mammarocoronary artery bypass graft to the anterior interventricular branch of the left coronary artery (MCABG-AIVB), as well as the role of the ...
