Over the past decades, various transcatheter devices have been invented and tested for safety and efficacy2. This manuscript aims to report a novel device and initial experience with the SinoCrown system (Lepu Medical Technology [Beijing] Co., Ltd).

SinoCrown has numerous unique design features that distinguish it from other self-expanding valves. It is made up of a self-expanding nitinol stent and three valve leaflets which are made of bovine pericardial tissue (Figure 1). It was designed with a short stent that could ...
