Succesful antegrade subintimal bypass restenting of in-stent chronic total occlusion.
Coronary chronic total occlusions (CTOs) are known to cause significant patient morbidity. Over the past several years, the techniques and devices for treating these CTOs have advanced tremendously. The interventional management of CTOs within previously placed coronary stents, however, remains challenging. Here, we present a case of an in-stent restenosis of the right coronary artery CTO bypassed using a controlled subintimal dissection re-entry technique via antegrade approach creating side-by-side stents.
