Physical Simulation of Transcatheter Edge-to-Edge Repair using Image-Derived 3D Printed Heart Models.

ABSTRACT:

Background

Transcatheter edge-to-edge valve repair (TEER) is a complex procedure requiring delivery and alignment of the device to the target valve, which can be challenging in atypical or surgically palliated anatomy. We demonstrate application of virtual and physical simulation to plan optimal TEER access and catheter path in normal and congenitally abnormal cardiac anatomy.

Methods

Three heart models were created from three-dimensional (3D) images and 3D printed, including two with congenital heart disease. TEER catheter course was simulated both virtually and physically using a commercial TEER system.

Results

We demonstrate application of modeling in three patients, including two with congenital heart disease and a Fontan circulation. Access site and pathway to de
