Clinical Outcomes Using Freestyle Valve–Valsalva Graft Composite Conduit for Aortic Root Replacement

From 2005 to 2020, 523 patients were treated using a novel method of aortic root replacement that used a self-constructed tissue valve conduit involving a Freestyle subcoronary valve sewn into a Valsalva graft. This study aimed to review the clinical outcomes of the method. Over the fifteen-year period, the five-year survival rate was 83 percent and the ten-year survival rate was 71 percent. Overall, the novel method produced excellent operative and ten-year outcomes, and valve durability was outstanding with low incidence for valve reintervention.
