Double-layer bare metal stents in the treatment of coronary artery aneurysm: experience and outcomes in nine patients

Introduction

A coronary artery aneurysm (CAA), defined as a localised dilation of a coronary artery segment >1.5 times the adjacent normal coronary diameter, can often pose significant diagnostic and management challenges1. Although various percutaneous treatment modalities have been described, controversies remain regarding the indication and the optimal choice of treatment2. Covered stents used in the repair of CAAs have demonstrated excellent angiographic results. However, their inflexibility, propensity to restenosis, and side branch occlusion may limit their utility and durability in patients with CAA3.

Using double layers of stents may provide adequate coverage of the neck of the ...
