Core Tip

Core Tip: We reported the determination of intervention by fractional flow reserve value measured via the left internal mammary artery after coronary artery bypass grafting in 2 cases. We provided evidence that fractional flow reserve measurement via grafted blood vessels, especially the left internal mammary artery, after coronary artery bypass grafting is a good method to determine whether to intervene.
