Antegrade filling of mammary graft by inappropriately revascularized artery.
A 57-year-old man underwent multiple-arterial revascularization including a sequential left internal mammary artery graft to the diagonal branch and left anterior descending coronary artery. Twenty-one months later, repeat angiography due to a new onset of chest discomfort confirmed string sign and nonfunctional proximal left internal mammary artery, and antegrade filling of the distal leg of the sequential graft and the left anterior descending artery through the diagonal branch. This is a known but uncommon angiographic finding that confirms the importance of eventual competitive flow.
