This study evaluated the impact of gender on Sievers types, valvulopathy, aortopathy, and outcomes of aortic valve replacement (AVR) in Chinese patients with bicuspid aortic valve (BAV). The results showed that male patients had more severe valvulopathy and aortopathy, as well as a higher risk of left ventricular dysfunction after AVR. Importantly, male patients developed these conditions at a younger age.
Background The gender difference of the bicuspid aortic valve (BAV) is not well understood. Objectives We evaluated the impact of gender on the Sievers types, valvulopathy, aortopathy, and outcomes of aortic valve replacement (AVR) of BAV patients in a cohort of Chinese patients. Methods Among 992 BAV patients without aortic dissection nor congenital heart disease, 658 underwent AVR. The demography, Sievers types, valvulopathy, aortopathy, and outcomes of AVR were compared between genders. Results Aortic regurgitation (AR >= 2+) (39.0% vs. 12.8%, p < .001), aortic root dilation only (3.8% vs. .8%, p = .014), and diffuse dilation (25.3% vs. 4.3%, p < .001) were more common in men, while moderate to severe aortic stenosis (AS) (21.3% vs. 45.7%, p < .001) and ascending dilation only (46.2% vs. 61.2%, p < .001) were more common in women. Men were more prone to develop preoperative AR >= 2+ (OR = 5.15, p < .001), moderate to severe AS + AR >= 2 + (OR = 2.95, p = .001), and Diffuse aortic dilation (OR = 3.91, p < .001). Sievers types did not have a significant effect on valvular dysfunction. Gender didn't predict early adverse events after AVR (n = 90) (HR = 1.21, p = .44), but male gender predicted a left ventricular ejection fraction <50% after AVR (OR = 3.07, p = .03). Conclusions In this BAV series of Chinese patients, gender didn't differ significantly in Sievers types of BAV but showed significant differences in valvulopathy, aortopathy, and LV function after AVR. In addition, the male patients developed more severe conditions at a younger age.
