| Popis: | Background There is conflicting evidence regarding the incidence of longitudinal stent deformation (LSD) in contemporary practice. Methods and results To assess the incidence and mechanism of LSD across commonly used DES platforms, we performed a case-by-case review of 1,800 PCI cases involving 450 consecutive procedures using Biomatrix Flex, Resolute Integrity, Promus Element and Xience V stents respectively, between Jan 2009-December 2011. LSD was detected in a higher proportion with Promus Element [15 (3.1%)] compared to other platforms (Xience V [4(0.9%)], Biomatrix [3 (0.7%)], Resolute [3 (0.7%)];p=0.002). LSD was characterised as guide catheter / guide extension induced, or as impact from secondary devices such as post-dilatation balloons or IVUS catheters. The incidence of guide catheter/guide extension LSD was similar across platforms; (Promus Element [5 (1.1%)], Xience V [4 (0.9%)], Biomatrix [3(0.7%)], Resolute [3 (0.7%)]; p=0.85). Secondary device LSD occurred exclusively with Promus Element (9/450 cases [2%] (p |
