2016, Journal of Thoracic and Cardiovascular SurgeryCitation Excerpt :However, reimplantation technique externally fixes the entire aortic valve complex within the tube graft, theoretically preventing late dilation of the aortic annulus and minimizing the risk of subsequent valve failure. Before 2002, we favored the remodeling technique because it allows for preservation of the sinuses, which minimizes valve leaflet stress and allows optimal aortic root function.28-31 Our initial experience with the remodeling technique yielded patients who developed AI and required late valve replacement, usually due to annular dilation.32,33

2015, Seminars in Thoracic and Cardiovascular SurgeryCitation Excerpt :However, the use of a straight tubular graft has always raised concerns about the nonphysiological rheology produced in the aortic box after the David I procedure.10 In fact, there is general agreement that the presence of sinuses reduces the stress on the leaflets and increases the freedom from the deterioration induced by the opening and closing cycles.3,11 On the contrary, different reports in literature lack to demonstrate a clear superiority of David I over neo-sinus-creating techniques (eg, Valsalva graft or David-V Stanford modification).12
