Why the study?
Longitudinal stent deformation is a potential complication of present generation drug-eluting stents, but reports of migration and dislodgement shortly after deployment remain limited.
Longitudinal stent deformation can occur up to 1.5 months after deployment, highlighting the importance of careful device manipulation and intravascular imaging during complex interventions.
Late DES foreshortening may occur months post-deployment; leaves open incidence, mechanisms, and surveillance needs.
The foreshortening of a stent also known as longitudinal stent deformation (LSD) is a potential complication of present generation drug-eluting stents (DES) that had thin struts design, and it was most commonly reported in the everolimus-eluting Promus Element stent. However, there are limited reports of migration and dislodgement of a DES shortly after its deployment. So, we describe a case of a DES foreshortening 1 and half months after its deployment. While performing complex interventions, careful handling and gentle manipulation of procedure-related devices and use of imaging modalities such as optical coherence tomography, intravascular ultrasound, and adjunctive balloons for complete lesion cover and optimal stent apposition may significantly reduce the occurrence of LSD and related complications.
