All rights reserved.We aimed to compare the safety and efficacy of rotational atherectomy (RA) and orbital atherectomy (OA) during percutaneous coronary intervention in an all-comer population with severely calcified lesions. We included all patients who underwent percutaneous coronary intervention with OA or RA in our institution from October 2013 until October 2016. Comparison of baseline and procedural characteristics, along with acute complication rates and postprocedural cardiac enzyme elevation, was performed. There were 191 RA and 57 OA patients. Other than creatinine clearance, which was lower in patients with OA (p=0.01), there were no differences in baseline characteristics. OA was more frequent in left anterior descending artery lesions (p=0.02), whereas RA was more common in right coronary artery lesions (p=0.01). Intracoronary imaging rates were above 60% in both groups. There was a higher rate of coronary dissections with OA compared with RA (p=0.003), but there was no difference in periprocedural events. Maximal troponin levels were similar in both groups. Residual stenosis measured by intravascular ultrasound in 29 patients revealed no significant differences between OA and RA (p=0.58). In conclusion, RA and OA have similar safety and efficacy profiles in treating patients with calcified coronary lesions, and intracoronary imaging is highly beneficial in identifying coronary injury after atherectomy procedures.All authors: Ben-Dor I, Bernardo NL, Buchanan KD, Gai J, Gallino RA, Garcia-Garcia HM, Kajita AH, Koifman E, Kuku KO, Lager R, Pichard AD, Rogers T, Satler LF, Steinvil A, Torguson R, Waksman RFiscal year: FY2018Digital Object Identifier:
