[Noninvasive angiography of coronary bypass grafts with cardio-CT in a cardiology practice].

Background: The role of coronary artery bypass surgery as a key foundation in the therapy of coronary artery disease remains unchanged: in Germany in 2001, 75,537 coronary bypass procedures were performed. However, the endurance of coronary bypass grafts is limited: after 3 years, 20-30% of the bypass grafts have occluded. The myocardial infarct rate significantly increases 8 years after bypass surgery.
