TCT-593 The Impact of Coronary Plaque Composition on Fractional Flow Reserve Improvement after Percutaneous Coronary Intervention: An Integrated-backscatter Intravascular Ultrasound Study

According to the pre-procedural IVUS measurement, severe stenosis group had smaller lumen area and larger plaque burden at minimal lumen site (1.75 ± 0.73mm2 vs. 2.49 ± 0.98mm2, p < 0.01; 82.9 ± 5.8% vs. 79.9 ± 5.4%, p = 0.011; respectively), whereas IB-IVUS derived lesion characteristics were al...

Zusammenfassung:According to the pre-procedural IVUS measurement, severe stenosis group had smaller lumen area and larger plaque burden at minimal lumen site (1.75 ± 0.73mm2 vs. 2.49 ± 0.98mm2, p < 0.01; 82.9 ± 5.8% vs. 79.9 ± 5.4%, p = 0.011; respectively), whereas IB-IVUS derived lesion characteristics were all similar between the 2 groups.
