Graft quality verification in coronary artery bypass graft surgery: how, when and why?

Kieser, Teresa M.


In Volume 32 Issue 6, the article, ‘Graft quality verification in coronary artery bypass graft surgery: how, when and why?’ [1], has an incorrect Figure 3c. Figure 3 should instead appear as follows:

The record is hereby corrected.

Purpose of review The coronary artery bypass graft (CABG) operation is one of the few remaining operations/interventions on diseased arteries that are not routinely verified during or immediately after the procedure. This review answers the ‘how’, ‘when’ and ‘why’ of intraoperative CABG assessment.

Recent findings More recent than new literature on this topic, is the increased interest in quality assurance of CABG. This is most likely due to reports in the last 5 years suggesting CABG superiority to percutaneous coronary intervention (PCI) for improved mid-term and long-term outcomes; for example, for patients with diabetes mellitus (Freedom Trial by Farkouh in 2012), and for patients with SYNTAX score ≥ 33 (SYNTAX Trial by Mohr in 2013). Possibly CABG is re-emerging from the era-of-better-and-better-stents and is now deemed worthy of improvement.

Summary In order to fully compliment PCI, the operative major adverse cardiac event rate of CABG must rival that of PCI. In order to reduce technical errors, it is best practice to perform intra-operative assessment of bypasses, especially since we have the tools.
