Transcatheter aortic valve implantation (TAVI) by using a double-layer ChenValve prosthesis. (a. Aortic angiography were performed to measure the diameter of the aortic annulus; b. A stiff guidewire was inserted and across the aortic valve into the descending aorta; c. Delivery device was inserted into LV from the heart apex; d. Three “fellers” of Outer-ring of Prosthesis was taken to locate the three aortic sinus; e. Prosthesis was expanded and released; f. The performance of the artificial valve was assessed by aortic angiography)
