Chronic competitive flow from a patent arterial or venous graft to the circumflex system does not impair the long-term patency of internal thoracic artery to left anterior descending grafts in patients with isolated predivisional left main disease: Long-term angiographic results of 2 different revascularization strategies

摘要

Objective: To compare 2 different surgical approaches to treatment of patients with isolated predivisional stenosis of the left main coronary artery (IOSLM) and to evaluate the effect of chronic competitive flow from a patent arterial or venous graft to the circumflex system on the long-term patency of internal thoracic artery (ITA) to left anterior descending grafts.
