New self-expanding TAVR valve shows promise


The team behind the analysis shared their thoughts on using the SinoCrown valve.

“The SinoCrown valve gradually unhooks from the delivery system via the rotary knob, so the valve is completely released and implanted separately,” wrote first author Qingrong Liu, PhD, a cardiologist with Chinese Academy of Medical Science and Peking Union Medical College, and colleagues. “One of its advantages is that it is 100% retrievable; prior to rotating the unlocking knob, the entire valve can be retrieved. According to the pathological conditions of the patient’s peripheral vascular disease, the SinoCrown can be delivered through a transfemoral or a transapical delivery system, both of which are suitable for the majority of aortic stenosis patients.”

Liu et al. also emphasized that it is still too early to make any sweeping comments or recommendations.

“More cases and long-term follow-ups are needed to evaluate the safety and efficacy of SinoCrown,” the group concluded.

This device is not approved to be used in the United States or anywhere else at this time.
