Comparison of outcomes and presentation in XXXX -versus- @entity1 with bicuspid aortic valves undergoing aortic valve replacement.

@entity4503 @entity1 @entity337
Gender disparities in short- and long-term outcomes have been documented in cardiac and valvular heart surgery. However, there is a paucity of data regarding these differences in the @entity4503 ( @entity4503 ) population. The aim of this study was to examine gender-specific differences in short- and long-term outcomes after surgical aortic valve (AV) replacement in @entity1 with @entity4503 . A retrospective analysis was performed in 628 consecutive @entity1 with @entity4503 who underwent AV surgery from April 2004 to December 2013. To reduce bias when comparing outcomes by gender, propensity score matching obtained on the basis of potential confounders was used. @entity1 with @entity4503 who underwent AV surgery presented with more advanced age (mean 60.7    13.8 vs 56.3    13.6 years, p <0.001) and less @entity337 (29% vs 44%, p <0.001) and had a higher risk for in-hospital mortality (mean Ambler score 3.4    4.4 vs 2.5    4.0, p = 0.015). After propensity score matching, @entity1 received more blood products postoperatively (48% vs 34%, p = 0.028) and had more prolonged postoperative lengths of stay (median 5 days [interquartile range 5 to 7] vs 5 days [interquartile range 4 to 6], p = 0.027). Operative, discharge, and 30-day mortality and overall survival were not significantly different. In conclusion, @entity1 with @entity4503 who underwent AV surgery were older, presented with less @entity337 , and had increased co-morbidities, lending higher operative risk. Although @entity1 received more blood products and had significantly longer lengths of stay, short- and long-term outcomes were similar.
