Abstract

Acute stent recoil or radial collapse of a stent is a rare phenomenon leading to subsequent acute stent thrombosis or in-stent restenosis as delayed sequelae. Reduced strut thickness, a larger stent/vessel ratio, and a larger balloon/stent ratio are factors leading to stent recoil. Here, we report a case of acute recoil or radial collapse of Promus Element Plus, a third-generation everolimus-eluting stent with thin stent struts in a 66 year-old male who underwent bifurcation percutaneous coronary intervention of left anterior descending artery (LAD) and diagonal branch (D1). Following kissing balloon inflation at 16 atm pressure after deployment of stents in LAD and D1, acute radial collapse of stent in proximal LAD was noted. It was successfully bailed out by further multiple, short sequential inflations using same size noncompliant balloon. Acute radial collapse probably occurred due to inflation at higher pressure with an oversized balloon, and relatively thin struts of the stent.
