Radiofrequency catheter ablation guided by intracardiac echocardiography.
BACKGROUND Radiofrequency catheter ablation requires precise positioning of the ablation electrode. Fluoroscopically guided catheter manipulation has limitations, and there are risks of radiation exposure. The purpose of this study was to examine the feasibility of guiding catheter ablation within the right atrium with catheter-based intracardiac echocardiography. METHODS AND RESULTS A 10F, 1...
متن کاملSimultaneous atrioventricular node ablation and leadless pacemaker implantation☆☆☆
Introduction The ablate-and-pace technique is a well-established method to treat patients with persistent and paroxysmal atrial fibrillation with poor rate control on medical therapy.1 The technique represents a class IIa indication to control heart rates when pharmacologic therapy is insufficient or intolerable.2 As many of these patients are in permanent atrial fibrillation, they frequently r...
متن کاملRadiofrequency catheter ablation of ventricular tachycardia guided by intracardiac echocardiography.
AIMS Ventricular tachycardia (VT) frequently has an anatomical substrate. Identification of areas prone to arrhythmogenicity facilitates radiofrequency catheter ablation (RFCA). Furthermore, direct monitoring of complications potentially increases safety of RFCA. The aim of this study was to evaluate the feasibility of guiding RFCA of VT with intracardiac echocardiography (ICE), in order to imp...
متن کاملRadiofrequency Catheter Ablation of Accessory Atrioventricular Connections
or paroxysmal supraventricular tachycardia involving a concealed accessory AV connection underwent catheter ablation with the use of radiofrequency current. In 179 of the 250 patients, catheter ablation was performed at the time of an initial electrophysiology test. Two hundred thirty-five patients had one accessory AV connection and 15 patients had two or more. One hundred eighty-three accesso...
متن کاملCharacteristics and radiofrequency catheter ablation of septal accessory atrioventricular pathways.
Septal accessory AV pathways are located in the complex AV septal space that also contains the specialized conduction system. They have unique electrocardiographical and electrophysiological characteristics to be differentiated from free-wall accessory pathways. Some of the septal pathways have AV nodelike conduction properties and produce a similar activation sequence in the retrograde conduct...
