Surgical dilemma - spare or replace regurgitant aortic valve: Late comparative outcomes of two strategies.

Background: To evaluate different aortic root surgery techniques and their contemporary clinical outcomes in patients with regurgitant aortic valve and aortic root aneurysm.

Methods: The study consisted of 141 adult patients who underwent aortic valve reimplantation (David group = 73) or aortic valve replacement surgery (Bentall group = 68) for aortic valve regurgitation (AR) and dilatation of the aortic root at our institution within the same period (April 2004-October 2016). Kaplan-Meier method was used to estimate survival and other clinically relevant outcomes between the groups.
