Congenital Heart Disease is a defect in the heart that is present at birth. In a group of these patients the pulmonary valve does not function properly and the valve needs to be replaced. As a prosthetic valve only has a limited lifespan these valve needs to be replaced a number of times during a life. To make the procedure less invasive Percutaneous Pulmonary Valve Implantation (PPVI) has been developed. 3mensio Pulmonary Valve is a dedicated workflow to plan PPVI. The automatic segmentation gives a quick overview of the patient’s anatomy. Different features enable the assessment of the surrounding structures and the planning of a stent and valve.
