“…We hope to shorten the procedure time by offering better navigation based on fluoroscopy overlay images, but further clinical studies are needed to confirm this. As of now, there are some some published results indicating that X-ray based navigation can at least shorten procedure time, e.g., when compared to the CARTO electromagnetic tracking system [52].…”

“…Pre-procedural CT and MRI datasets can also be co-registered with electroanatomic maps (EAM) prior to ablation [3–5] or overlaid directly onto live fluoroscopic images in the electrophysiology laboratory [6–7]. There remains controversy over the need for image integration with EAM.…”

“…While most studies suggest that integration reduces procedural duration, recurrence of AF and radiation exposure from fluoroscopy [4–5, 8–9] one study does not [4]. CT image reconstruction overlaid onto fluoroscopy has been shown to shorten duration of PV isolation compared to conventional CT image integration with EAM [6–7]. Further studies are required to assess if pre-procedural CT/MRI image integration with EAM or fluoroscopy improves procedural and clinical outcomes.…”

Preprocedural Imaging for Patients with Atrial Fibrillation and Heart Failure

Various electrophysiological procedures and device implantation has been shown to improve morbidity and mortality in patients with atrial fibrillation (AF) and patients with heart failure (HF). Non-invasive cardiac imaging is used extensively in the pre-procedural patient selection and for procedural guidance. In this review, we will discuss the application of pre-procedural cardiac imaging in patients with AF prior to pulmonary vein and left atrial ablation as well as insertion of left atrial occluder device. We also discuss the role of non-invasive cardiac imaging in the selection of appropriate HF patients for device therapy as well as their use in guiding implantation of biventricular pacemaker for cardiac resynchronization therapy by assessing left ventricular ejection fraction, coronary venous anatomy, mechanical dyssynchrony and myocardial scar. We describe new research associated with pre-procedural imaging in these patient cohorts.

“…Although the images obtained of the left atrium were of great value to the operator, unfortunately, CT images could not be displayed concurrently with the fluoroscopic imaging acquired in the electrophysiology lab during the procedure initially. Sophisticated software was used to bridge the gap by development of systems capable of overlaying the segmented CT images of the left atrium directly onto the live fluoroscopy screen [36] or into a 3D electroanatomic mapping system [37–42]. For the electrophysiologist, this brought the beginning of 3D representation of individual patient's cardiac anatomy into the procedural lab, displayed over real-time fluoroscopy.…”

Over the last fifteen years, our understanding of the pathophysiology of atrial fibrillation (AF) has paved the way for ablation to be utilized as an effective treatment option. With the aim of gaining more detailed anatomical representation, advances have been made using various imaging modalities, both before and during the ablation procedure, in planning and execution. Options have flourished from procedural fluoroscopy, electroanatomic mapping systems, preprocedural computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and combinations of these technologies. Exciting work is underway in an effort to allow the electrophysiologist to assess scar formation in real time. One advantage would be to lessen the learning curve for what are very complex procedures. The hope of these developments is to improve the likelihood of a successful ablation procedure and to allow more patients access to this treatment.

Three‐Dimensional CT Overlay in Comparison to CartoMerge for Pulmonary Vein Antrum Isolation

Abstract: CT overlay for PV isolation is feasible and may, in comparison to conventional LA navigation systems, shorten procedural time without increases in radiation burden.
