Imaging in CABG Patients.

Purpose of the review: Coronary artery bypass grafting (CABG) is one of the most common major surgical procedures performed. Atherosclerosis however is a progressive condition; it is probably therefore that patients with CABG will represent with ischemic symptoms. The purpose of this review is to provide familiarity with testing in CABG patients to assist clinicians in their decision-making. Recent findings: CT angiography of coronary arteries and grafts (CCTA) has evolved into an alternative approach to diagnose graft disease or occlusion. As such, CCTA may help risk stratify patients post-CABG. CCTA thus joins the armamentarium of traditional functional tests that can be used. The consequences of which type of test is chosen are discussed. Summary: Through discussion of the contemporary literature for imaging in CABG patients, this review will focus on the strengths and weaknesses of both anatomical and functional approaches. It appears that the impact of which index test is chosen is as important post-CABG as it is in patients with suspected CAD. [ABSTRACT FROM AUTHOR]
