Abstract
The choice of graft used to bypass stenoses in the coronary circulation is crucial to coronary artery bypass grafting
(CABG) surgery and its success. Herein is a review of the existing literature on CABG grafts, including the
discussion of utilization of different CABG grafts, patency of different grafts, and technical and other considerations
pertinent to the use of each graft. Lastly, we present special considerations for graft selection in women.

Keywords: Coronary artery bypass grafting, graft selection, conduit selection

INTRODUCTION
Coronary artery bypass grafting (CABG) provides blood flow distal to flow-limiting and non-flow-limiting
coronary artery stenoses for the treatment of coronary artery disease (CAD). The choice of graft to bypass
these stenoses is therefore of utmost importance to maximize the efficacy and biological benefits of CABG.
Herein, we review the current literature on CABG grafts, their utilization in current clinical practice, and
the most recent evidence on graft patency. We also review technical and anatomic considerations specific to
the use of each graft, including harvesting technique, grafting strategy, and target vessel, among others.
Lastly, given that women comprise roughly one-third of the CABG population yet have well-described
