5 | CONCLUSION
Stepwise cardiac computed tomography manipulation to mimic
trans-esophageal echocardiography is the last piece of the puzzle to
achieve mental co-registration of the three important imaging
modalities. With a high quality electrocardiogram gated cardiac CT, we
are enabled to foresee the fluoroscopy projections and TEE images in a
preoperative rehearsal to decide the interventional fluoroscopy
projection angles according to the patient-specific conditions, and to
assist the interventional echocardiographer to plan the imaging.
