Relation between coronary plaque calcium deposits as described by computed tomography coronary angiography and acute results of stent deployment as assessed by intravascular ultrasound.

ABSTRACT:

Introduction

The findings from intravascular ultrasound studies on the impact of calcium deposits on the results of stent implantation are conflicting.

Aim

To evaluate whether calcium deposits as assessed by (CTCA) influence results of stent deployment.

Material and methods

The study population comprised 60 patients (43 male; age 64.2 ±8.6 years) who underwent CTCA before stent implantation. Lesion calcium score, total calcium length, and maximal area and maximal thickness of calcium deposits within the lesion segment were assessed. Plaques were divided into those with calcium score ≥ median (group 1), calcium score < median (group 2), and without calcium (group 3). Intravascular ultrasound (IVUS) was performed after attainment of optimal angiographic results of the s
