Missing grafts and the potential for inappropriate revascularization.

ABSTRACT

The best outcome for coronary intervention in coronary artery bypass graft patients requires knowledge of prior coronary anatomy. This information is not always available as many cases present acutely, especially in ST-elevation myocardial infarction. We present three cases in which bypass grafts were documented as occluded but follow-up angiograms for other reasons revealed that the grafts were still patent. This presents the potential for inappropriate revascularizations.
