Abstract

Abstract: Cardiac electrophysiology is an evolving specialty that has seen rapid advances in recent years. Concurrently, there has been much progress in the field of cardiac imaging. Electrophysiologists are increasingly requesting cross-sectional imaging in advance of many procedures. Pulmonary vein isolation and left atrial appendage (LAA) occlusion are now an established treatment options for atrial fibrillation. In patients undergoing pulmonary vein isolation, applications of computed tomography (CT) include evaluating the left atrial and pulmonary venous anatomy, excluding LAA thrombus and assessing for pulmonary vein stenosis. In those undergoing LAA occlusion, CT may be of value in assessing the size, position, and morphology of the LAA as well as for determining correct positioning of the device and evaluating for peri-device leak. Implantable cardiac devices are now commonly used in the management of cardiac failure and cardiac arrhythmias. Applications of CT prior to device implantation include detecting myocardial scar, evaluating for mechanical dyssynchrony as well as visualising the coronary venous anatomy.
