Subintimal tracking and reentry (STAR) for CTO

Subintimal tracking and reentry (STAR) for CTO

Subintimal tracking and reentry (STAR) technique is used when there is failure to cross coronary occlusion (CTO) with conventional approaches. Apart from the risk of perforation, periprocedural myocardial infarction and stent thrombosis have been raised as the potential risks associated with this approach.
