Established guidelines recommend consideration for concomitant surgical aortic valve replacement (SAVR) at time of coronary artery bypass grafting (CABG) in patients with moderate aortic stenosis (AS) to avoid future reoperation for AS progression. The advent of transcatheter aortic valve replacement allows for treatment of AS without mediastinal entry. This questions the optimal treatment choice of moderate AS in patients undergoing CABG. We compared outcomes of CABG with or without SAVR in patients with moderate AS.
