**3.6 J-valve Ausper system**

J-valve Ausper system by Jiecheng Medical Technology has been certified by China FDA for AR. It consists of bovine pericardial leaflets with nitinol stent frame within three U-shaped anchor rings (**Figure 7**). The earlier device was designed to be delivered via transapical access. A large-scale single-center Chinese study for severe AS and severe AR showed acceptable safety with 3% and 3.7% mortality at 30 days and 6 months, respectively [41]. The newer device can be delivered by a transfemoral approach using an 18 F sheath. Available sizes are 21 mm, 23 mm, 25 mm, 27 mm, and 29 mm.
