Orbital atherectomy of calcified coronary ostial lesions.

ABSTRACT:

Objectives

To evaluate the feasibility and safety of coronary orbital atherectomy (OA) for the treatment of calcified ostial lesions.

Background

Percutaneous coronary intervention (PCI) is increasingly being completed in complex patients and lesions. OA is effective for severely calcified coronary lesions; however, there is a dearth of evidence on the use of OA in ostial lesions, especially with long-term outcome data.

Methods

Data were obtained from a retrospective analysis of patients who underwent OA of heavily calcified ostial lesions followed by stent implantation from December 2010 to June 2019 at two high-volume PCI centers. Kaplan-Meier analysis was utilized to assess the primary endpoints of 30-day, 1-year, and 2-year freedom-from (FF) major adverse cardiac e
