Background: Data on the impact of gender on outcomes of surgical aortic valve replacement (AVR) are controversial. In the STS risk score model, female gender was an independent risk factor for morbidity and mortality after AVR. However, several recent studies have suggested that the gender gap after AVR is narrowing. We sought to compare the gender differences in outcomes of aortic valve replacement.
Methods: The 2004-2013 Nationwide Inpatient Sample was utilized to identify 138,092 patients who underwent isolated SAVR. Multivariable logistic regression derived propensity scores were sequenced and matched 1:1 to attain 45,557 matched pairs of isolated SAVR in males and females to assess in-hospital outcomes and cost.
Results: Of 138,092 who underwent isolated AVR, only 86720 (37.2%) were females. In-hospital mortality was higher in females (5.6% vs 4.3%, p< 0.001), as were vascular complications (7.3% vs 6.6% %, p< 0.001), stroke (1.9% vs 1.5%, p=0.003), pacemaker implantation (7.3% vs 7%, p=0.007) and blood transfusions (41.8% vs 36.2%, p=< 0.001).
Conclusions: Women undergo AVR much less frequently than men in a contemporary U.S Practice. Female gender is an independent predictor of mortality in patients undergoing aortic valve replacement. The advent of transcatheter aortic valve replacement and evidence of less mortality when compared to surgical aortic valve replacement.
