    Abstract:
    Stroke is a potential complication of treating patients with aortic stenosis via surgical aortic valve replacement (AVR), transcatheter aortic valve replacement (TAVR), and balloon aortic valvuloplasty. Because there are limited and heterogeneous data on the incidence, risk factors, and outcomes of stroke among patients being treated for aortic stenosis, we performed a comprehensive review of the literature. The risk of stroke after AVR in the general population is approximately 1.5%, and the risk is increased (to approximately 2% to 4%) in older and higher-risk patients. Strokes were reported in 1.5% to 6% of patients treated with TAVR, and in the only randomized trial of AVR versus TAVR, there was an increased risk of 30-day strokes (minor and major strokes and transient ischemic attacks) with TAVR (5.5% vs. 2.4%, p = 0.04).
