Comparison of clinical outcomes of intravascular ultrasound-calcified nodule between percutaneous coronary intervention with versus without rotational atherectomy in a propensity-score matched analysis.

ABSTRACT:

Objectives

This study aimed to compare the mid-term clinical outcomes of intravascular ultrasound (IVUS)-calcified nodules between percutaneous coronary intervention (PCI) with and without rotational atherectomy (RA).

Background

There has been a debate whether to use RA for the revascularization of calcified nodule. Although RA can ablate the calcified structure within calcified nodule and may facilitate adequate stent expansion, RA may provoke severe coronary perforation, because calcified nodule typically shows eccentric calcification.

Methods

We included 204 lesions with IVUS-calcified nodule, and divided into 73 lesions treated with RA (RA group) and 131 lesions without RA (non-RA group). After propensity-score matching, 42 lesions with RA (matched RA group) and 4
