Why the study?
Does exercise thallium-201 myocardial scintigraphy accurately evaluate graft patency and occlusion in patients after aortocoronary bypass graft surgery?
Does exercise thallium-201 myocardial scintigraphy accurately evaluate graft patency and occlusion in patients after aortocoronary bypass graft surgery?
Exercise thallium-201 scintigraphy is accurate for assessing graft patency in non-infarcted myocardium and frequently detects residual ischemia in ungrafted territories, suggesting the need for more comprehensive grafting.
No takes yet. Share an insight, caveat, or question.
May support noninvasive graft assessment in non-infarcted myocardium; leaves open routine post-CABG use pending prospective validation.
Wainwright et al. (1980) studied this question.
