Successful bypass restenting across the struts of an occluded subintimal stent in chronic total occlusion using a retrograde approach.

Abstract
Recently, subintimal angioplasty has been introduced as a bailout strategy to improve the success rate of PCI for vessels with CTO. However, the long-term outcome of subintimal angioplasty has not been determined, and a limitation of subintimal angioplasty is the uncertainty in making the re-entry point. We report two cases, where occlusive in-stent restenosis occurred in a stent implanted in the subintimal space of the RCA that had CTO. These two cases were successfully treated with bypass restenting across the struts of an occluded subintimal stent using a retrograde approach. A retrograde wire crossed the occluded segment through the lumen along the outside of the stent and reentered the inside of the stent across the stent struts. The reverse CART technique followed by multiple restenting across the stent struts restored antegrade flow. Follow-up angiography demonstrated the patency of the RCA.
