Functional assessment of jailed side branches in coronary bifurcation lesions using fractional flow reserve.
OBJECTIVES This study was designed to assess the functional significance of side branches after stent implantation in main vessels using fractional flow reserve (FFR). BACKGROUND Little is known about the functional significance of side branches after stent implantation in main vessels in coronary bifurcation lesions. METHODS Between May 2007 and January 2011, 230 side branches in 230 patie...
متن کاملPhysiological evaluation of the provisional side-branch intervention strategy for bifurcation lesions using fractional flow reserve.
AIMS This study was performed to evaluate the functional outcomes of fractional flow reserve (FFR)-guided jailed side-branch (SB) intervention strategy. METHODS AND RESULTS One hundred and ten patients treated by provisional strategy were consecutively enrolled and SB FFR was measured in 91 patients. SB intervention was allowed when FFR was <0.75. FFR measurement was repeated after SB interve...
متن کاملEvaluation of Local Flow Conditions in Jailed Side Branch Lesions Using Computational Fluid Dynamics
BACKGROUND AND OBJECTIVES Lesions of vascular bifurcation and their treatment outcomes have been evaluated by anatomical and physiological methods, such as intravascular ultrasound and fractional flow reserve (FFR). However, local changes in flow dynamics in lesions of bifurcation have not been well evaluated. This study aimed at evaluating changes in the local flow patterns of bifurcation lesi...
متن کاملComprehensive assessment of coronary fractional flow reserve
Fractional flow reserve (FFR) is considered nowadays as the gold standard for invasive assessment of physiologic stenosis significance and an indispensable tool for decision-making in coronary revascularization. Robust studies have shown that FFR is more effective in accurately identifying which lesions should be stented, and revascularization guided by FFR improves the outcome of coronary arte...
متن کاملPhysiologic Assessment of Coronary Artery Disease: Focus on Fractional Flow Reserve.
The presence of myocardial ischemia is the most important prognostic factor in patients with ischemic heart disease. Fractional flow reserve (FFR) is a gold standard invasive method used to detect the stenosis-specific myocardial ischemia. FFR-guided revascularization strategy is superior to angiography-guided strategy. The recently developed hyperemia-free index, instantaneous wave free ratio ...
