Treatment of a coronary bifurcation lesion with drug-coated balloons: lumen enlargement and plaque modification after 6 months

Abstract

We report a male with a coronary bifurcation lesion in the mid circumflex artery (CX). After predilatation, the lesion was treated with two drug-coated balloons (DCB). Primary success in the posterolateral branch was good; however the CX lesion had a residual stenosis including a non-flow-limiting type A dissection. After 6months, angiography showed slight lumen enlargement in both branches of the bifurcation. Intravascular ultrasound identified about 35% atherosclerotic plaque load within the inner area of the bifurcation but more than 50% concentric atherosclerotic plaque burden in the vessel areas proximal and distal to the DCB-treated area.
