Successful stent ablation with rotational atherectomy.

We describe the findings from two patients with coronary artery disease treated with stents who had unexpandable rings after deployment. These covered rings were successfully ablated with rotational atherectomy. The treated segment was then scaffolded with a new stent. Our observations confirm the efficacy of rotational atherectomy for stent ablation. Copyright 2003 Wiley-Liss, Inc.
