Impact of obesity on long-term survival after aortic valve replacement with a small prosthesis

Although many studies have evaluated the impact of obesity on various medical treatments, it is not known whether obesity is related to late mortality with implantation of small aortic prostheses. This study evaluated the effect of obesity on the late survival of patients after aortic valve replacement (AVR) with implantation of a small aortic prosthesis (size ≤ 21 mm).
