“…The thickness of the struts ranges between 81 and 140 m. Number of connectors determines the stent flexibility and deliverability, side branch access and longitudinal integrity (Table 1). 5,6 Stents with less number of connectors may be prone to deformation when subjected to longitudinal compressive or elongating forces. This happens in following clinical scenarios during PCI: (1) crossing the deployed stent with non-compliant balloon for post dilatation, the most commonly reported cause for longitudinal compression, (2) guide catheter or its extensions coming in contact with the stent, either in case of stent in the ostial location or guide catheter deep seating, (3) IVUS catheter pull back for post stent deployment assessment, (4) withdrawal of the stent delivery system following stent deployment when the balloon gets stuck in the struts, (5) crossing the newly deployed stent with another stent for the treatment of a distal lesion, (6) wire entanglement.…”

IntroductionCoronary stents, especially drug eluting stents (DES), have revolutionized the practice of interventional cardiology. With the availability of newer stent designs with better deliverability and conformability, more complex coronary subsets are now effectively managed with percutaneous intervention rather than coronary artery bypass surgery. 1 However, these newer stents have issues previously unknown with older platforms. Longitudinal compression, one such issue with newer DES platforms, has caused concern among the interventionist. 2e5 We report a case of such deformation in a patient who underwent percutaneous intervention for a mid left anterior coronary artery (LAD) lesion. Case reportA 67 year old female, diabetic, hypertensive and hypothyroid was evaluated for exertional chest pain of CCS class III. Her exercise stress test was strongly positive for inducible ischemia and the coronary angiogram showed a 12 mm long concentric 80% type B stenosis in LAD starting just beyond the second septal branch (Fig. 1A).* Corresponding author.
