Longitudinal Stent Deformation at Aneurysm Site: Flexibility at the Expense of Longitudinal Integrity.

Longitudinal stent deformation is a recently described complication of percutaneous coronary intervention. Novel stents with thin struts and reduced number of fixed links between cells improve flexibility and deliverability but in certain cases it may reduce longitudinal strength and thereby increase the risk of longitudinal deformation. Although longitudinal deformation of coronary stents is an infrequent finding, it requires clinical attention as it may lead to catastrophic clinical outcomes. We report a case of longitudinal deformation of coronary stent observed at our institution while treating ostial lesion and aneurysm of left anterior descending artery. Longitudinal deformation was identified during the procedure and treated with the deployment of another stent. Three-month follow-up of the patient was found satisfactory without any incidence of stent thrombosis.
