Figure 1. Fusion model during the procedure. A) Model after segmentation of preprocedural MSCT. B) Matched 3D-TEE and MSCT segmentation. Orange: coronary arteries and aorta. Pink: left ventricle. C) Pre-implantation verification with small contrast injection. D) Optimal implantation depth localisation. E) Checking possible interference of the prosthetic valve with the mitral valve (yellow). F) Post-implantation verification with small contrast injection.

Several tools have been developed in order to optimise transcatheter aortic valve implantation (TAVI) procedures and decrease the risk of procedural complications such as acute kidney injury. Real-time fusion of 3D multislice computed tomography (3D-MSCT) images with X-ray ...
