Unicuspid aortic valve 单叶式主动脉瓣

ttc1140) F, 47 y. BSA= 1.34 m2; BMI= 27.6 Kg/m2. Possible unicuspid AV. Massive fibrotic thickening of the AV cusps at 2D imaging (Figs 1-5) in severe AS (Mean gradient= 85 mmHg; Fig. 6) and associated mild AR (Fig. 2). Short axis imaging shows apparent tricuspid valve, but surgeon reports absence of commissures and probable unicuspid valve (Figures 7-8). Figure 9 shows massive fibrotic tissue been removed surgically piece by piece. A mechanical bi-leaflet prosthesis (#16) was implanted.
单叶式主动脉瓣可能。 在重度主动脉瓣狭窄(平均压差= 85 mmHg;图6)的2D图像中,主动脉瓣瓣叶大量纤维化增厚(图1-5),且与轻度主动脉瓣返流相关(图2)。 短轴图像显示出明显的三叶式瓣膜,但医生报告了瓣叶交界缺失,单叶式主动脉瓣可能(图7-8)。图9显示大量纤维化组织通过手术被一片片移除,植入了一个二叶机械人造瓣(#16)。
