Key result
Rotational atherectomy in chronic total occlusion lesions demonstrated similar procedural success (94.7% vs 96.2%) and complication rates (4.0% vs 2.5%) compared to non-CTO lesions.
Why the study?
Data on rotational atherectomy in CTO are rare, and procedural success and complication rates compared with non-CTO lesions are unknown.
Does rotational atherectomy in CTO lesions have similar procedural success and complication rates compared to non-CTO lesions?
Observational (n=392)
Does rotational atherectomy in CTO lesions have similar procedural success and complication rates compared to non-CTO lesions?
Absolute Event Rate: 94.7% vs 96.2%
Rotational atherectomy in chronic total occlusion lesions is as safe and effective as in non-CTO lesions, even in the presence of prior dissections.
May support rotational atherectomy in CTO lesions; extends observational data but remains hypothesis-generating.

Brinkmann et al. (2018) conducted an observational in Coronary artery disease requiring PCI with rotational atherectomy (n=392). Rotational atherectomy in CTO lesions vs. Rotational atherectomy in non-CTO lesions was evaluated on Procedural success. Rotational atherectomy in chronic total occlusion lesions demonstrated similar procedural success (94.7% vs 96.2%) and complication rates (4.0% vs 2.5%) compared to non-CTO lesions.
