Three-Dimensional Modeling of Surgically Implanted Stent-Based Valves in the Mitral Position in Children

PurposeIn children with a mitral annulus too small to accommodate traditional prostheses, surgical implantation of stent-based valves is a promising option. However no reliable preoperative methods exist to guide patient selection, device sizing, and positioning. We describe a novel methodology to visualize and quantify device fit in 3-dimensional echocardiogram (3DE)-derived heart models.DescriptionHeart models were created from existing...
