Should the left main be covered entirely with drug-eluting stents in percutaneous intervention.

Restenosis after percutaneous intervention in the left main coronary artery may present as sudden cardiac death. Although drug-eluting stents have demonstrated promising results, there remains the question about appropriate length of the left main artery to be covered with the stent. We describe a patient who received two drug-eluting stents with the balloon crushing technique in the distal left main coronary artery. Three months later, this patient presented with a new lesion in the segment of the left main artery not covered with stent, but instead at the site where the balloon was inflated in the initial procedure.
