Aims: The aim of this study was to evaluate the clinical and echocardiographic results and the predictors of outcomes in patients undergoing valve-sparing operation (VSO) at two aortic centers. In addition, we sought to evaluate the potential effect of recreation of the sinuses of Valsalva (SV) on the outcome of valve-sparing procedures. Methods: During a 14-year period, 328 patients underwent aortic valve-sparing root replacement at two institutions. Clinical and echo evaluation was performed 6 months after surgery and every year thereafter or in case of clinical symptoms. Propensity weighting and propensity-weighted risk competing analysis were used. Results: No operative mortality was reported; the most common complication was revision for bleeding, occurring in 15 patients (4.6%). At a mean follow-up of 30.0 ± 33.9 months, two patients died (0.6%). Recurrent aortic insufficiency (AI) >2+ was found in 11 patients (3.3%); five (1.5%) underwent reoperation. Recreation of the SV did not affect clinical outcome and aortic valve status. Need for aortic valve repair was the only independent predictor of recurrent AI, whereas a bicuspid aortic valve was a protective factor. Conclusions: Re-creation of the SV does not affect short-term outcomes following VSO.

Abstract
Aims: The aim of this study was to evaluate the clinical and echocardiographic results and the predictors of outcomes in patients undergoing valve-sparing operation (VSO) at two aortic centers. In addition, we sought to evaluate the potential effect of recreation of the sinuses of Valsalva (SV) on the outcome of valve-sparing procedures. Methods: During a 14-year period, 328 patients underwent aortic valve-sparing root replacement at two institutions. Clinical and echo evaluation was performed 6 months after surgery and every year thereafter or in case of clinical symptoms. Propensity weighting and propensity-weighted risk competing analysis were used. Results: No operative mortality was reported; the most common complication was revision for bleeding, occurring in 15 patients (4.6%). At a mean follow-up of 30.0 ± 33.9 months, two patients died (0.6%). Recurrent aortic insufficiency (AI) >2+ was found in 11 patients (3.3%); five (1.5%) underwent reoperation. Recreation of the SV did not affect clinical outcome and aortic valve status. Need for aortic valve repair was the only independent predictor of recurrent AI, whereas a bicuspid aortic valve was a protective factor. Conclusions: Re-creation of the SV does not affect short-term outcomes following VSO.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
