The First Application of Domestically Produced Self-expanding Transcatheter Aortic Valve Controllable Bending Delivery System in China / 中国循环杂志

A domestically produced self-expanding transcatheter aortic valve controllable bending delivery system(VitaFlow? Ⅲcontrollable bending retrievable delivery system)was first used to perform transcatheter aortic valve replacement(TAVR)in a symptomatic severe aortic valve stenosis patient with severe heart failure and high risk of surgery in China on September 22,2023.The patient successfully completed TAVR under general anesthesia,with good valve position and function after the operation.Before discharge and at one month of follow-up,the patient's symptoms and degree of heart failure were significantly improved.The follow-up results of this case showed that the VitaFlow? Ⅲ controllable bending retrievable delivery system for TAVR is safe and feasible,and future prospective,multicenter clinical trials are expected to evaluate its efficacy.

Aortic Root Imaging and Clinical Application in 15 Patients With Transcatheter Aortic Valve Implantation--A Single Center Early Experience / 中国循环杂志

Objective: To study the aortic root imaging and clinical application in 15 patients with transcatheter aortic valve implantation (TAVI). Methods: A total of 15 patients with severe aortic valve stenosis received TAVI in our hospital from 2011-03 to 2013-11 were studied. The CT scan and transthoracic echocardiography were conducted to measure the aortic root anatomy and the differences of annulus size between CT and echocardiography were calculated. The prosthetic valves were selected based on CT measurement. The pre-operative accuracy of measurement was evaluated by the follow-up study at 6 months after operation. Results: The CT measured pre-operative aortic annulus short diameter was (21.5 ± 2.4) mm, long diameter was (27.3 ± 2.7) mm, the average inner diameter was (24.4 ± 2.4) mm, left ventricular out lfow (LVOF) tract long diameter was (28.3 ± 4.5) mm, the average inner diameter of LVOF was (24 ± 3.5), ascending aorta diameter was (35.3 ± 4.4) mm. The Venus Medtech A-Valve implanted in 8 patients with #26 and in 7 patients with #29. The average inner diameter of aortic annulus measured by CT was larger than transthoracic echocardiography, P Conclusion: There is a difference for aortic annulus size by CT and transthoracic echocardiography measurements. CT may presisely assess the aortic root morphology and provide strong support for TAVI.
