Preoperative angiography in combination with intraoperative graft flow measurements may improve durability of coronary artery bypass grafts. However, native coronary flow might impair bypass graft flow based on stenoses’ severity, leading to inferior long-term outcomes. Intraoperative routine snaring of a coronary artery detects significant competitive flow, possibly intercepting unnecessary perioperative graft revisions.
