[Treatment of chronic total coronary occlusions by the subintimal tracking and reentry modified technique. The contrast-guided STAR technique].

Background: Previous data showed that recanalization of chronic total occlusions (CTO) with the subintimal tracking and reentry (STAR) technique is feasible. However, this technique is challenging and requires skilled operators to be performed. The aim of this study was to evaluate procedural and clinical outcomes of patients undergoing a contrast-guided STAR procedure.
