Why the study?
What are the frequency and mechanisms of longitudinal stent deformation, and is it associated with specific stent types?

Longitudinal stent deformation is a mechanical complication that carries a risk of stent thrombosis and was observed more frequently with the Promus Element stent in this retrospective analysis.

May warrant thrombosis vigilance with Promus Element; leaves open causal mechanisms and design mitigation in prospective studies.
Longitudinal stent deformation can occur secondary to a variety of mechanisms and identification is important as, left untreated, it may be associated with a risk of stent thrombosis. Although seen with several different stents, in our series it was more commonly observed with the Promus Element stent.
