Preoperative angiography and intraoperative transit time flow measurement to detect coronary graft patency in reoperations: an integrated approach--a case report.
Coronary angiography is the gold standard for preoperative diagnosis of coronary artery disease. In reoperative coronary artery surgery the physiologic significance of suspect lesions by angiography can be confirmed by direct intraoperative measurement of blood flow in the old grafts; such interpretation can prevent unnecessary graft revisions.
