Background: Venus P-valveTM (Venus Medtech, Hangzhou, China) is a selfexpandable
bioprosthetic valve that can be transcatheter-implanted in native
right ventricular outflow tract (RVOT) patients. Valve implantation is technically
challenging. Due to the implantation technique, left pulmonary artery (LPA) stents
represent a relative contraindication to Venus P-valve. In this case series, we
describe our experience in implanting Venus P-valve in patients with previous LPA
stents and the use of holographic models to facilitate procedural planning.
Methods and results: From January to October 2023, 17 patients were
scheduled for Venus P-Valve implantation. 16/17 (94%) patients were
successfully implanted. 3/16 (18.7%) patients underwent Venus P-valve
implantation with LPA stents. All patients underwent pre-operative CT scan.
CT data set were employed to create three-dimensional (3D) holographic
models (Artiness, Milan, Italy) of the entire heart, which were useful to plan
valve implantation with a modified technique. Procedural success rate was
100%. No procedural complications occurred. All three patients presented
good haemodynamic and angiographic results at discharge and follow-up visits.
Conclusion: This case-series underscores the feasibility of Venus P-valve
implantation in patients with previous LPA stents. The use of holographic
models facilitated procedural planning in these challenging anatomical scenarios.
