A Novel Cardiac Computed Tomography-Based Calcium Scoring System for Predicting the Use of Atherectomy Devices in Severely Calcified Coronary Lesions.

ABSTRACT:

Background

Cardiac computed tomography (CT) is a well-established process used to diagnose coronary artery disease; however, its specific advantages in predicting the use of atherectomy devices during percutaneous coronary intervention (PCI) for moderate to severe calcified lesions remain to be determined. This study aimed to develop a risk scoring system for predicting the use of atherectomy devices in PCI on the basis of morphological findings obtained by preoperative cardiac CT.

Methods

In this retrospective, multicenter, observational study, we screened patients who underwent cardiac CT 6 months before PCI for the target lesion. Consequently, 498 de novo stenotic lesions from 415 patients with moderate to severe calcification were included. Then, 70% of the cohort (deriv
