We evaluated the safety and efficacy of this novel implant with imaging follow-up at 6-months, the time point when the bioadaptor starts to uncage. This prospective study enrolled 44 patients with up to two de novo lesions at seven centers in New Zealand treated with the DynamX Bioadaptor. Follow-up was planned out to 12-months. The primary safety and efficacy endpoints were 6-month target lesion failure (TLF) and late lumen loss. Patients presented with non-ST elevation myocardial infarction in 49%. Lesions (<i>n</i> = 45) were 16.0 ± 6.7 mm long, and 2.81 ± 0.41 mm in diameter. Device and procedure success were 100%, and acute lumen gain was 1.93 ± 0.35 mm. At 6-months, median in-device late lumen loss was 0.09 mm (IQR:0.05–0.16). Measured by intravascular ultrasound, the vessel, lumen, and device area remained constant. By optical coherence tomography, 96.4% ± 5.9% of struts per lesion were covered. Out to 12-months, no TLF and no definite or probable device thrombosis were reported.

The use of adjunctive anti-Rx devices was associated with a significant reduction in operator radiation exposure compared to standard radioprotection (12.8 <i>μ</i>Sv [7–21] and 22.6 <i>μ</i>Sv [11–36], respectively; <i>p</i> &lt; 0.0001). Globally, the anti-Rx devices utilized were associated with a reduced operator radiation exposure (11.7 <i>μ</i>Sv [2–19] for homemade drapes, 13.5 <i>μ</i>Sv [9–29] for RADPAD drape, 15 <i>μ</i>Sv [11–30] for STAR Board System, and 8 <i>μ</i>Sv [5–19] for Rampart; <i>p</i> &lt; 0.0001) with the homemade drapes and the Rampart system showing a lower operator exposure. <i>Conclusions</i>. The use of anti-Rx devices during percutaneous coronary procedures is associated with a significant lower operator radiation exposure with the greater effect obtained with pelvic drapes and the Rampart system.</p>\u0000 </div>","PeriodicalId":16329,"journal":{"name":"Journal of interventional cardiology","volume":"2024 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/8815778","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
