title: Stent "concertina:" stent design does matter.
abstract: The development of modern coronary stent platforms has transformed the landscape of interventional cardiology. Contemporary coronary stents are much more deliverable than older-generation stents. However, longitudinal deformation has emerged as a "new" complication in modern coronary stent platforms. Although most reported cases of longitudinal stent deformation involve mechanical or technical mishaps, it appears that it is more frequently associated with a particular stent design: the "offset peak-to-peak" stent design. This review summarizes the latest data around stent performance. Within this context, two clinical cases where longitudinal deformation was observed in the absence of any mechanical mishaps are also presented. Collectively, this evidence suggests that stent design may be a major determinant of stent performance.
