Orbital Atherectomy Combined with Lithotripsy in a Right Coronary Artery Chronic Total Occlusion

Abstract

Percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) can be challenging, especially if the CTOs are balloon uncrossable or balloon undilatable. We present a case illustrating that, orbital atherectomy may need to be combined with intravascular lithotripsy for CTOs that are both balloon uncrossable and undilatable.
