Clinical impact of direct rotational atherectomy in patients with complex coronary artery lesions.

ABSTRACT: Owing to limited data on the optimal timing of rotational atherectomy (RA), we sought to evaluate the clinical impact of the early application of the RA strategy. Consecutive patients with severe coronary artery calcification were enrolled, who underwent percutaneous coronary intervention (PCI) using RA between January 2010 and October 2019 at 9 tertiary centers. Direct RA was defined as the early application of RA before the balloon was expanded to a size more than or equal to 2.0 mm. The primary endpoint was the composite outcome of technical failure or severe coronary dissection (type D, E, or F) during entire procedure. Of 581 lesions, 360 (62.0%) lesions underwent direct RA. The technical success rate was higher in the direct RA group than in the indirect RA group (97.5% vs. 93.7%, p
