| Popis: | Modern ultrathin struts drug eluting stents (DES), due to their constructive characteristics, might be more prone to stent dislodgment than the old thick DES. Our study is aimed to retrospectively analyze and compare the incidence and outcomes of stents dislodgment in thick (TSS) and ultrathin strut stents (USS).We retrospectively analyzed the procedural and medical data of 8,564 consecutive patients (mean age 64.3 ± 11.2 years old, 4442 males) who underwent percutaneous coronary intervention with DES implantation in our Institution between 1st January 2005 to 1st January 2020. Overall, 25,692 (mean of 3.2 stent for patients) have been implanted over the study period (10648 TSS and 15044 and USS, respectively). Stent dislodgment globally occurred in 0.56% of the implanted stents (0.28% vs 0.78%, p0.001 for TTS and USS, respectively). Coronary artery calcifications, ostial lesion, coronary artery tortuosity, and a lesion length25 mm were independent predictors of type I and II USS dislodgments. At 12 months follow up, the rate of target lesion failure was higher in the TTS group (30.7 vs 12.7 %, p0.001). Stent dislodgement is unusual in the modern era but is more frequent using USS than TTS DES. |
