Plaque modification of severely calcified coronary lesions via orbital atherectomy: Single-center observations from a complex Veterans Affairs cohort.

ABSTRACT:

Background

Orbital atherectomy (OA) is a known alternative to other atherectomy devices. However, some complex patient demographics (eg, left ventricular ejection fraction <25%) were excluded from the first-in-human trial (ORBIT I) and the pivotal FDA device approval trial (ORBIT II) which evaluated the safety and efficacy of OA in severely calcified de novo coronary lesions. This single-operator cohort study aimed to examine the impact of OA on a real-world complex Veterans Affairs patient subset.

Methods

Retrospective analysis was completed on 40 consecutive patients with severely calcified coronary lesions who underwent OA prior to drug-eluting stent placement at the Atlanta Veterans Affairs Medical Center from January 2015 to June 2017.
