Abstract

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 bicuspid aortic valve (BAV) 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 patients with BAV. A retrospective analysis was performed in 628 consecutive patients with BAV 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. Women with BAV 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 aortic regurgitation (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, women 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, women with BAV who underwent AV surgery were older, presented with less aortic regurgitation, and had increased co-morbidities, lending higher operative risk. Although women received more blood products and had significantly longer lengths of stay, short- and long-term outcomes were similar.
