To evaluate procedure outcomes, complications, and the predictors of device success while using Tornus in CTO revascularization.The percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) may be limited by presence severe calcified lesions, especially smallest balloon uncrossable arteries. A penetrating (Tornus) could improve rate.Device angiographic rates as well procedural complications were assessed 56 patients, who consecutively retrospectively enrolled into this study. Device was defined successful passage catheter through a lesion. Procedure final TIMI 3 flow <30% residual stenosis.The rate 71.4% 40 patients failure 28.6% 16 patients. The significantly higher group compared with (87.5% vs. 37.5%, P < 0.001). One patient (1.8%) had wire perforation resulting cardiac tamponade death. Another acute in-stent thrombosis non-Q MI 24 hr resuscitated emergent PCI. only independent predictor calcium score 2 (odds ratio (OR): 3.86 (95% CI: 1.14-13.1, = 0.03).The can used PCI when <2 not ≥2.
