title: StentBoost used to guide management of a critical ostial right coronary artery lesion.
abstract: This report describes a case of a critical ostial lesion of a dominant right coronary artery (RCA) in a patient with poor left ventricular function due to a previous anterior infarction and documented late drug-eluting stent thrombosis of the RCA. The precise non-invasive determination of the proximal edge of a previously deployed stent by a new imaging technique, StentBoost, showed the lesion not only to be proximal to the stent in the uncovered ostium, but also restricted to the section outside the stent. This, together with the patient's clinical factors, suggested that stent placement was the optimal treatment strategy.
