Figure 1 Cumulative frequency distribution of the late lumen loss at follow-up in cutting balloon angioplasty (CBA), percutaneous transluminal coronary angioplasty (PTCA), rotational atherectomy (ROTA), and additional stenting (STENT) groups. Significantly lower lumen loss noticed in CBA group compared to ROTA and STENT groups (0.63 ± 0.6 mm, 1.30 ± 0.8 mm, and 1.36 ± 0.8 mm; p < 0.0001).

Figure 2 Acute angiographic and intravascular ultrasound (IVUS) results obtained after cutting balloon angioplasty (CBA) for in-stent restenosis (ISR) in left circumflex artery. (a) Preintervention IVUS image shows complete neointimal filling of the lumen in the stent (lumen cross-sectional area 1.3 mm2; (b) Final result following CBA with 2.5-mm balloon (lumen cross-sectional area 6.0 mm2).
