Figure 1 The correlation between the lesion site MLD by QCA (2.26 ± 0.82 mm) and IVUS (2.81 ± 0.82 mm was r = 0.364, p = 0.0005 [Panel A]). The correlation between the QCA reference diameter (3.91 ± 0.76 mm) and IVUS (4.25 ± 0.78 mm) was r = 0.492, p = 0.0001 (Panel B). IVUS = intravascular ultrasound; MLD = minimum lumen diameter; QCA = quantitative coronary angiography.
