3D anatomical model saves time and reduces risk on a rare transcatheter pulmonary valve replacement

  • Cardiology


Earlier this year, a 44-year-old woman was prepared to undergo a percutaneous pulmonary valve implantation. Also known as transcatheter pulmonary valve replacement, this is the replacement of the pulmonary valve via catheterization through a vein. This means the shape or size of the Right Atrial Appendage is affecting the blood flow into the right ventricle. To be able to perform this surgery they requested a conduit of the great arteries.


The key reason for the request for a 3D model was because the procedure that was going to be performed is very rare and the team needed a guide with sufficient precision to help them throughout this surgery. By having this model, it changed their pre-operative plans, with a further knock on of having a very positive effect on physician communication and education. It also helped greatly with patient communication and consent before operating, as the physician was able to physically show the patient what the outcome of the procedure was going to be on a physical 3D model.


The outcome of this procedure was very successful, saving over 120 minutes in surgery and reducing the recovery time of the patient significantly. The physician expressed that using a 3D model instead of a 2D image was invaluable as it confirmed the surgery would have been too risky without medical management. By using this 3D anatomical model, the patient's anxiety decreased greatly before surgery. She was also exposed to less risk during the procedure and recovery in hospital due to using the model.
