- W2022600153 abstract "The Wiktor coronary stent has been implanted in 82 lesions in 68 patients. The indication for stent implantation was 49 elective (57%), 10 threatened closure (12%), 9 SUboptimal PTCA (11%), 7 chronic total occlusion (9%), 4 restenosis (5%), and 3 acute occlusion (4%). Vessel distribution was 39 RCA (48%), 31 LAD (37%) and 12 LCX (15%). Successful stent implantation was achieved in 77 lesions (94%). Average Wiktor stent per lesion was 1.4 ± 0.8 (range 1 to 4). More than one stent was used in 53 patients (69%). Lesion length was 14.8 ± 9.7 mm. Final balloon/vessel ratio was 1.03 ± 0.15. Maximum inflation pressure was 16 ± 3 atmospheres. There were 5 lesions that required an additional Palmaz-Schatz stent inside the Wiktor to reinforce the lumen support. Mild stent structural deformity (expanded strut gap) was seen in 8 lesions. There were 5 stents with severe stent deformity due to shrinkage (n = 3) or uncoiling (n = 2). 59 patients (93%) with 72 lesions (88%) of were treated with only antiplatelet therapy after stent implantation with intravascular ultrasound guidance. There were 2 CABG due to stent severe stent deformity. One death was due to femoral artery occlusion with multiple organ failure. To date, 35 of an eligible 59 lesions (59%) received 4–6 months angiographic follow up (F/U).AG resultsReference (mm)Lesion (mm)% stenosisBaseline3.18 ± 0.420.73 ± 0.4973 ± 16Post stent3.20 ± 0.362.98 ± 0.396 ± 10F/U297 ± 0.492.02 ± 0.7328 ± 26 There was one stent thrombosis that occurred 8 days after the stent procedure and 5 days after antiplatelet therapy was inadvertently stopped. Wiktor stent restenosis by ≥ 50% diameter stenosis was present in 8 patients (23%). (1) Short term results and restenosis rate after Wiktor stent implantation without subsequent anticoagultion is encouraging. (2) Mild or significant structural deformity was found in 13 (16%) of stents." @default.
