There were 122 patients (38%) with moderate-to-severe AR, of whom 82 (67%) underwent Liu\u2019s aortic root repair and valve preservation. Aortic computed tomography angiography and echocardiography were performed at discharge, 6 and 12\u2009months postoperatively, and annually thereafter. We focused on assessing the survival and aortic root and valve durability in the 82 patients.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The 30-day, 1-year, 3-year and 6-year survival estimates were 94%, 90%, 85% and 81%, respectively. At a median follow-up of 36.5 (interquartile range 24.9\u201350.9) months, all patients were free from reoperation. No residual false lumens in the aortic root, recurrent aortic root dissections or aortic root pseudoaneurysms were observed during the follow-up period. Only 1 patient (1%) presented with moderate AR at 6\u2009months, which remained asymptomatic with no significant changes over a 3-year period. The remaining patients showed satisfactory valve function with an AR grade of mild (27%) or trace or none (72%). In the competing risk analysis, the incidence of recurrence of AR was 2% at 8\u2009years.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n
