Impact of coronary calcium morphology on intravascular lithotripsy.

ABSTRACT:

Background

Coronary calcification negatively impacts optimal stenting. Intravascular lithotripsy (IVL) is a new calcium modification technique.

Aims

We aimed to assess the impact of different calcium morphologies on IVL efficacy.

Methods

This was a prospective, multicentre study (13 tertiary referral centres). Optical coherence tomography (OCT) was performed before and after IVL, and after stenting. OCT-defined calcium morphologies were concentric (mean calcium arc >180°) and eccentric (mean calcium arc ≤180°). The primary outcomes were angiographic success (residual stenosis <20%) and the presence of fracture by OCT in concentric versus eccentric lesions.

Results

Ninety patients were included with a total of 95 lesions: 47 concentric and 48 eccentric. The medi
