Data presented as percentage or mean ± standard deviation. Neurologic events, reintervention, and surgical site infections were tracked to postoperative day 30; otherwise, complications were tracked only during index admission.

AV indicates aortic valve; EKG, electrocardiogram; GI, gastrointestinal; ICU, intensive care unit; LOS, length of stay; PPM, permanent pacemaker; TIA, transient ischemic attack; VTE, venous thromboembolism.
