title: Anchoring improved: introduction of a new over-the-wire support balloon.
abstract: Coronary chronic total occlusion (CTO) interventions continue to be technically challenging for interventional cardiologists despite the advent of multiple devices and techniques. Successful CTO percutaneous coronary intervention (PCI) has proven to improve symptoms, long-term mortality, and ejection fraction. We present a case of a patient with symptomatic right coronary artery (RCA) CTO who failed maximal medical therapy as well as multiple antegrade PCI attempts. Successful RCA CTO intervention was finally achieved using a novel over-the-wire balloon catheter (Prodigy; Radius Medical) in an antegrade fashion.
