Longitudinal stent deformation during coronary intervention: A report of three cases

Abstract

Recently, longitudinal stent deformation (LSD) has been increasingly reported with 2nd generation drug eluting stents (DES). Though, the reported cases are with all type of stents, it is common with Promus Element stent. It is either caused by impact of guide catheter’s tip at proximal or osteal stent site, or following secondary passage of catheters like balloon catheters, IVUS or OCT catheters, guideliner, etc. We hereby report 3 cases of LSD who had this technical complication because of three different reasons. All of them were successfully managed, and had favorable short term outcomes.
