VenusP-Valve, an in-house developed novel medical device of Venus Medtech (Hangzhou) Inc. (2500.HK, hereinafter referred to as “Venus Medtech”), recently completed its first compassionate use at University of Virginia Advanced Cardiac Valve Center in the U.S.

The procedure was performed at the Center by Professor Scott Lim’s team under on-site guidance from Professor Yuan Feng and remote guidance from Professor Mao Chen, who are both from Cardiology Department, West China Hospital, Sichuan University in China. As the first-ever clinical application of a Chinese-developed heart valve product in the U.S., the case corroborates not only the unique clinical value of VenusP-Valve™ but also the significance of global-oriented innovation.
Although there are several transcatheter pulmonic valve replacement (TPVR) products available in the U.S. market, such as Melody™ TPV and Harmony™ TPV by Medtronic and the SAPIEN series by Edwards, they do not work for the considerable number of patients with dilated right ventricular outflow tract (RVOT). As a large-diameter product, VenusP-Valve™ can satisfy the clinical needs of 85% of patients in the case of large RVOT. In May 2022, VenusP-Valve™ was approved by the FDA for compassionate use in two patients.
This first patient was a 21-year-old man who suffered from severe pulmonary regurgitation, right ventricular dilation, pulmonary artery dilation, and left ventricular dysfunction after transannular patch (TAP) repair of Tetralogy of Fallot (TOF). The procedure was performed under local anesthesia where the patient remained conscious. Upon preoperative CT, intraoperative contrast-enhanced ultrasound, and balloon measurement, a P34-25 (valve diameter 34mm, straight length 25mm) VenusP-Valve™ that precisely fit the patient’s anatomy was delivered through the right femoral vein. On the first postoperative day, ultrasound scan indicated a marked decrease in right ventricle volume with no pulmonary regurgitation. Left ventricular function also returned to normal. Making a sound recovery according to postoperative assessment, the patient was discharged on June 18 (within 24 hours of the procedure) local time.
“It was a great honor to work with Professor Chen and Professor Feng on the first compassionate use of VenusP-Valve™ in the United States”, commented Professor Scott Lim after the procedure. “The product was very easy to handle as it’s designed to facilitate precise positioning and delivery. The patient demonstrated significant improvement after the procedure. For the benefit of more patients, I really look forward to formal clinical trials of VenusP-Valve™ here as soon as possible.”
