Saphenous vein graft failure and clinical outcomes: toward a surrogate end point in patients following coronary artery bypass surgery?

Published

Journal Article

Saphenous vein graft (SVG) failure is a common finding in patients following coronary artery bypass graft (CABG) surgery. In the literature SVG failure rates have been reported from 25 to over 50% within 10 years. Although common, it remains unclear to what extent SVG failure affects clinical outcome, due to differences in definition, patient selection and follow-up. Particularly the lack of agreement on a universal definition makes comparisons between studies, and therefore generalizability of associations with outcomes, challenging. We suggest using a definition of SVG failure that is based on imaging as well as clinical parameters, that includes reporting SVG failure on both graft and patient level. The use of non-invasive imaging may help improve follow-up rates, and provide a more accurate picture of the real incidence and clinical impact of SVG failure. Given the lack of supportive evidence showing a consistent association between SVG failure and major adverse cardiovascular events, SVG failure should not be considered a valid surrogate endpoint at this time.
