Published by Elsevier Inc.Abstract: The current iterations of balloon-expandable transcatheter aortic valve replacement (TAVR) valves consist of a maximum size of 29mm, corresponding to maximum annulus area of 680mm<sup>2</sup>. However, a number of patients who qualify for TAVR based on surgical risk may have anatomical features outside the FDA-approved descriptions. The technique of overexpansion of TAVR valves during deployment allows for more patients to be treated successfully. This particular case demonstrates that overexpansion is safe and efficacious in a very large annulus of >800mm<sup>2</sup>. Careful planning and consideration of aortic root calcification is helpful for technique of overexpansion and, ultimately, the technique may increase the number of patients eligible for TAVR.
