Abstract

Cardiac computed tomography (CT) is increasingly used to plan transcatheter structural heart interventions, however, intra-operative guidance relies on trans-esophageal echocardiography (TEE) and fluoroscopy. This study sought to develop the methods of stepwise CT multi-planar reconstruction manipulation to mimic TEE thus bridging the gap between preoperative planning and intra-operative guidance tools. This CT manipulation successfully reproduces similar configurations as TEE views in mid-esophageal left ventricle (LV) views, transgastric LV 2-chamber views for mitral apparatus, and other miscellaneous views. Stepwise cardiac CT manipulation to mimic TEE is the final piece of the puzzle in the mental co-registration of these three crucial imaging modalities. With it, we are enabled to foresee the TEE images and fluoroscopy projections in a preoperative rehearsal thus improving the intra-operative accuracy of interventions.
