Effect of Operator Experience Performing Rotational Atherectomy on Clinical Outcomes After Percutaneous Coronary Intervention.

ABSTRACT:

Background and objectives

Rotational atherectomy (RA) is a technique used to ablate calcified plaques. There is speculation that operators' experience with RA could play a role in the outcomes.

Methods

From December 2015 to April 2020, patients with calcified coronary lesions requiring percutaneous coronary intervention (PCI) with RA were enrolled in a prospective, multicenter, observational registry. The patients were divided into two groups based on the number of RAs performed by their operator in the past. A propensity score matching was done for a sensitivity analysis. The primary outcome was a composite of cardiac death, myocardial infarction, and target vessel revascularization at 1 year.

Results

A total of 497 patients were enrolled in the study. The calculated
