Key result
Peak-to-peak stent designs improve simulated longitudinal compression by ~30%, driven primarily by connector number.
Why the study?
Longitudinal stent compression is a newly identified failure mode in coronary stents, with unclear contributions of stent design features to its development.
Does stent design pattern and connector number affect longitudinal stent compression in coronary stents?
Does stent design pattern and connector number affect longitudinal stent compression in coronary stents?
Computational modeling demonstrates that increasing the number of connectors and utilizing a peak-to-peak design pattern can significantly reduce the risk of longitudinal stent compression in coronary stents.

Stent connector optimization may reduce longitudinal compression risk; hypothesis-generating simulations leave clinical validation open.
Hsiao et al. (2014) studied Longitudinal stent compression. Stent design pattern and connector number vs. Alternative stent designs (Element vs Endeavor) was evaluated on Longitudinal stent compression (LSC). Computational simulations demonstrated that stent connector number primarily drives longitudinal stent compression, which improved by up to 30% when using a peak-to-peak design.
