A new mapping method to estimate exit sites of ventricular arrhythmias using intracardiac echocardiography and M-mode for catheter ablation
BACKGROUND Catheter ablation of premature ventricular complexes (PVCs) has been used as a curative therapy in many cases. Intracardiac ultrasound with a magnetic sensor probe has recently become available for catheter ablation. In this study, we assessed a new mapping method, contraction mapping, for determining the optimal ablation sites using intracardiac ultrasound and M-mode. This study sou...
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 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 کاملCatheter ablation of atrial fibrillation without fluoroscopy using intracardiac echocardiography and electroanatomic mapping.
BACKGROUND Catheter ablation of atrial fibrillation is currently guided by x-ray fluoroscopy. The associated radiation risk to patients and medical staff may be significant. We report an atrial fibrillation ablation technique using intracardiac echocardiography (ICE) and electroanatomic mapping without fluoroscopy. METHODS AND RESULTS Twenty-one patients with atrial fibrillation (age, 42 to 7...
متن کاملCatheter Ablation of Ventricular Arrhythmias: Clinical Vignettes
Ventricular arrhythmias (VA) can develop in patients with structural heart disease (SHD) including prior myocardial infarction and nonischemic cardiomyopathy. When VAs manifest in structurally normal hearts, they are usually a result of intra-cellular calcium overload (triggered activity) or an abnormal response to adrenergic stimulation (automaticity).1 Reentry within the Purkinje fibers and s...
