Early and mid-term angiographic assessment of internal thoracic artery grafts anastomosed to non-stenotic left anterior descending coronary arteries

In addition, residual flow from the native Coronary artery has been Proposed as a mechanism that reduces blood flow in bypass grafts resulting in failure of the graft
