Rigatelli G, Zuin M, Vassilev D, et al. - By retrospectively studying data of 8,564 consecutive patients (mean age 64.3 ± 11.2 years old, 4,442 men) who received percutaneous coronary intervention with drug eluting stents (DES) implantation, researchers compared the incidence as well as results of stents dislodgment in thick (TSS) and ultrathin strut stents (USS). A total of 25,692 (mean of 3.2 stent for patients) were implanted over the study span, including 10,648 TSS and 15,044 and USS, respectively. A global occurrence of stent dislodgment in 0.56% of the implanted stents was revealed (0.28% vs 0.78% for TTS and USS, respectively). Factors that independently predicted type I and II USS dislodgments were: coronary artery calcifications, ostial lesion, coronary artery tortuosity, and a lesion length > 25 mm. A higher rate of target lesion failure was observed, at 12 months follow up, in the TTS group. Overall, findings although revealed an unusual occurrence of stent dislodgement in the modern era but its occurrence has been seen more often using USS than TTS DES.
