    Abstract:
    Serious complications including vessel perforation may occur during rotational atherectomy (RA) to left circumflex (LCX) ostial lesions. In fact, if perforation occurs around LCX ostium, bailout procedures including deployment of covered stents may cause fatal ischemia in the territory of left anterior descending artery, which results in broad anterior acute myocardial infarction and subsequent death. In this review article, we described tips and tricks for RA to LCX ostial lesions. First, we should cautiously decide the indication for RA to LCX ostial lesions, because there are several reasons to avoid RA to LCX ostial lesions. Before procedures, we should estimate the difficulty of RA to LCX ostial lesions, which is mainly determined by the combination of the bifurcation angle and the severity of stenosis. Thus, the combination of the large bifurcation angle and the tight stenosis makes RA to LCX ostial lesions most difficult. Appropriate position of guide catheter and RotaWire is a key to successful RA to LCX ostial lesions. Differential cutting is an essential concept for RA to LCX ostial lesions. However, since there is no guarantee that differential cutting always works, small burr (≤ 1.5 mm) would be a safe choice as initial burr for RA to LCX ostial lesions.
