Experience with CartoSound for arrhythmia ablation in pediatric and congenital heart disease patients

Successful catheter ablation using real-time ultrasound-assisted 3-D electroanatomical mapping system for atrioventricular accessory pathway in a 1-year-old girl with criss-cross heart

“…The CARTOSOUND system has a substantial advantage in allowing modeling of anatomical shapes. During tachycardia, the CARTOSOUND system provides the most accurate real-time geometry and reveals the catheter position on real-time echo images 9 . The CARTOSOUND system enables the depiction of the ultrasonic contours in an arbitrary phase of the heart cycle, which results in more accurate merging with electrocardiography-gated angiographic images, such as coronary CT angiograms.…”

“…Concerning esophageal probe placement, images obtained using the CARTOSOUND system are adequate for anatomy evaluation but inferior to those obtained from the use of an intravascular catheter. This method represents “off-label” use of the SOUNDSTAR catheter 9 . In addition, SOUNDSTAR may increase risk of esophageal injury because it does not have a thermosensor for preventing esophageal scalding.…”

Usefulness of a crista catheter for 3-dimensional electroanatomical mapping of complex right atrial tachyarrhythmias

“…CartoSound is the integration system of 3D electroanatomic mapping and intracardiac echocardiography. More accurate anatomic model and geometry can be obtained by CartoSound [17]. Paso module can deliver automated ECG-template matching during ventricular tachycardia mapping.…”

Atrial tachyarrhythmias after atrial switch operation for transposition of the great arteries: Treating old surgery with new catheters

“…26,31,34,46,64 Advantages of using ICE during the electrophysiological study include demonstration of catheter position and ablative lesions, monitoring pulmonary venous flows and tissue contact, identification of relevant anatomical structures and early detection of potential complications including interatrial communications or cardiac tamponade. 22,31,34,46,64 Reported disadvantages include the relatively large sheath required for ICE and a significant part of the procedure time devoted to visualization of the cardiac anatomy. 64 Integration of 3D computed tomography (CT) or cardiovascular magnetic resonance (CMR) images with real-time intraprocedural electranatomical mapping has also been reported for ablation of atrial arrhythmias in patients after atrial switch correction.…”
