Abstract
Surgical planning for coronary artery bypass grafting (CABG) can be enhanced with the use of computed tomographic (CT) imaging to better understand the surgical field for optimal conduct of the case as well as risk assessment for outcomes. CABG via primary sternotomy, redo sternotomy, and minimally-invasive thoracotomy each pose unique surgical considerations and risks that can be better characterized with a preoperative CT scan. CT and CT angiographic (CTA) techniques with or without intravenous (IV) contrast can provide a noninvasive assessment of the vascular and bony structures and direct surgical planning techniques. Herein we discuss the role of CT/CTA imaging of the chest in preoperative planning of different strategies of CABG.
