Case Study: King Faisal Specialist Hospital & Research Centre achieves optimal device fit for PPVI in wide RVOT anatomies with Materialise 3D‑printed models

Optimal Device Fit for PPVI in Wide RVOT Anatomies

At King Faisal Specialist Hospital & Research Centre, Dr. Mansour AlJufan and his team faced particularly wide and irregular right ventricular outflow tract (RVOT) anatomies that made percutaneous pulmonary valve implantation (PPVI) high‑risk and hard to plan. Materialise supported the team with the Mimics® Innovation Suite to create patient‑specific digital RVOT reconstructions and delivered 3D‑printed anatomical models (rigid stereolithography and HeartPrint® Flex) to simulate and rehearse complex interventions.

Using Materialise’s models, the team tested balloon sizing, stent stability and device deployment both before and during procedures, enabling the successful implantation of a 29 mm Edwards Lifesciences bioprosthetic valve (the largest percutaneously implanted valve reported in this series). The simulations reduced procedure time, shortened recovery, helped avoid open‑heart surgery, and gave clinicians the confidence to perform a novel large‑size PPVI with measurable clinical benefit.
