Cutting balloons and scoring balloons are commonly used for the preparation of calcified lesion. However, problems with crossability occasionally limit the use of cutting balloons. We prospectively selected 173 calcified lesions treated using a novel cutting balloon (Wolverine™, C group). As control, we retrospectively analyzed 146 calcified lesions treated using a scoring balloon (Lacrosse NSE ALPHA™, S group). Either intravascular ultrasound (IVUS) or optical coherence tomography (OCT) was used by the operators discretion. The primary outcome was delivery success, which was defined as successful passage to the target lesion immediately after IVUS or OCT evaluation. The secondary outcome was acute cross-sectional area (CSA) gain, which was defined as post-interventional minimum stent area minus pre-procedural minimum lumen area. A multivariate analysis evaluated the independent predictors for delivery success. The ...
