Abstract/OtherAbstract:
AIMS AND OBJECTIVES: New electrophysiology tools like intracardiac echocardiography (ICE) might help to minimize and early detect complications during cardiac ablation procedures. The aim of the study was to assess the utility and vascular safety of ICE during catheter ablation of complex cardiac arrhythmias in a medium-volume training center.
METHODS: Prospective, observational study consisted of consecutive patients who underwent catheter-based ablation of complex cardiac arrhythmias. All procedures were performed using three-dimensional electro-anatomical mapping and routine cannulation of right and left femoral veins. The ICE probe was initially positioned at the mid-level of the right atrium and properly moved to monitor different steps of the procedure and identify complications. All procedure-related vascular complications were registered.
RESULTS: One hundred two patients (age 61.4 ± 13.1 years, 69 male) underwent 110 ablation procedures. Pulmonary vein isolation was the most common ablation substrate (55.4%). Ventricular tachycardia (17.2%) and left atrial flutter procedures (16.4%) were also common. The use of ICE enabled us to early initiate anticoagulation and to optimize the transseptal puncture. It also provided the capability to early detect life-threatening complications such as tamponade (3.6%), along with important information during the procedure such as exact catheter location, lesion formation, and stability during radiofrequency delivery. Such benefits were not associated with a higher number of vascular complications.
CONCLUSION: The use of ICE during catheter-based ablation of complex cardiac substrates provides technical features that may decrease complications and increase accuracy while applying radiofrequency, especially in training centers where fellows start to perform complex procedures.
