In a patient with a recently placed stent, a stress echocardiogram clearly indicated ischemia in the territory of the stented vessel. Subsequent coronary angiography, undertaken because of presumed restenosis, showed the stented area to be widely patent. This prompted a review of stress echocardiograms performed in patients within 6 weeks of coronary stenting. Of 21 such cases, 3 additional patients were found to have false-positive results in the territory served by the stented vessel.
