We describe a 39-year-old man presenting with non-ST elevation myocardial infarction (NSTEMI) who underwent PCI of the left circumflex artery (LCx). After implantation, a drug-eluting stent unexpectedly migrated backward into the left main coronary artery (LMCA). An attempt to capture it with a snare via the femoral approach was unsuccessful. Using a balloon anchoring maneuver, the stent was carefully advanced to the radial artery and fixed in position with an additional stent, preserving arterial flow. PCI of the LCx was then completed with a good angiographic outcome. This case underlines the importance of choosing an appropriate stent size, recognizing predisposing factors such as vessel spasm, and being familiar with different retrieval or management techniques to deal with such rare complications.</p>","PeriodicalId":94261,"journal":{"name":"Turk Kardiyoloji Dernegi arsivi : Turk Kardiyoloji Derneginin yayin organidir","volume":" ","pages":"524-527"},"PeriodicalIF":0.6,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145954641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Higher AIP levels were associated with lower technical success rates. To assess the incremental predictive value of AIP, two nested models (Model 1 and Model 2) were constructed. Model discrimination improved with the inclusion of AIP (area under the curve [AUC]: 0.73 vs. 0.83), and likelihood ratio testing confirmed a significant enhancement in model performance (P < 0.001). In both models, estimated glomerular filtration rate and the Japanese Chronic Total Occlusion (J-CTO) score remained independent predictors of CTO PCI technical success. In Model 2, AIP was also independently associated with technical success (odds ratio: 0.03, 95% confidence interval: 0.01-0.12, P < 0.001).
