“…Ischemic myocardium with regional wall motion abnormalities and infarcted scar or fibrous wall can be identified by its thinning, increased echodensity, akinesis or dyskinesis. The ablation catheter tip can be easily guided to and monitored while ablating at specific structures, such as a “false tendon,” mitral valvular insertion, or papillary muscle 1 . In addition, ICE can monitor lesion morphologic changes to prevent the development of significantly accelerated bubbles, sudden “popping” and tissue disruption.…”

“…Novel echocardiographic techniques, such as intracardiac echocardiography (ICE) 1 and 3D echocardiography 2–3 have improved imaging of intracardiac structures and diagnostic capabilities, especially for interventional cardiology/electrophysiology. ICE with an electronic phased array transducer catheter provides 2D and color flow imaging to assess detailed cardiac anatomy and function of the left heart from the right atrium/ventricle during ablation procedures.…”

Catheter-based radiofrequency ablation in the left heart can provide effective therapy for tachyarrhythmias. The recent development of the real time intracardiac echocardiography (ICE) with 2D and Doppler color flow imaging can facilitate left heart ablation procedures. This report reviews the use of ICE during radiofrequency catheter ablation procedures for atrial fibrillation (AF) and ventricular tachycardia and is based on our own experience in 955 patients. ICE has a critical role for guiding transseptal catheterization, assisting placement of mapping/ablation catheters and monitoring lesion morphologic changes, especially in the pulmonary vein ostia, Marshall ligament region, thickened interatrial septum, left atrial posterior wall contiguous to esophagus, aortic valve cusps, and the epicardial regions. One of the more powerful utilities of ICE lies in its ability to identify and potentially reduce procedural complications including damage to intracardiac structures, residual atrial septal defect, left atrial thrombus formation, pulmonary vein stenosis, esophageal injury, myocardial air-embolization and pericardial effusion during left heart ablation.
