Reappraisal Value of a Modified Rotational Atherectomy Technique in Contemporary Coronary Angioplasty Era.

ABSTRACT:

Objectives

To introduce a modified rotational atherectomy (RA) procedure and investigate the early and midterm outcomes of the RA-facilitating diversified percutaneous coronary intervention (PCI) in a large group of aged patients with higher cardiovascular risk.

Background

Previous studies about the outcomes of RA were limited with small sample size and low-risk population.

Methods

Between January 2013 and November 2015, 1169 consecutive patients treated with modified RA-facilitated PCI were retrospectively enrolled, including de novo calcified lesions and in-stent restenosis.
