Stepwise manipulation of cardiac computed tomography multi-planar
reconstruction to mimic trans-esophageal echocardiography
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.
