We present a case of a 69-year-old male who was hospitalized for the treatment of thyroid storm due to Grave’s disease, who presented with unexpected ventricular fibrillation (VF). The possible etiology was early repolarization (ER), characterized by J-point elevation in inferior and posterolateral leads, unmasked by the attenuation of beta-adrener...

BackgroundDiscrimination of local and far field potentials during sinus rhythm and atrial fibrillation (AF) is essential for successful pulmonary vein (PV) isolation. We sought to introduce an expert system for the classification of electrophysiologic PV signals.MethodsFor the expert system database, we analyzed ablation procedures of 50 patients w...

BackgroundAs damage to coronary arteries is a potential complication of epicardial RF catheter ablation (EPRFCA), the procedure must be associated with coronary angiography. Chronic Chagasic cardiomiopathy (CCC) is a disease where epicardial VT are common. Eletroanatomic mapping merged with computed totmography (CT) scan data is a useful tool for m...

PurposeLeft atrial ablation is increasingly used to treat patients with symptomatic atrial fibrillation (AF). Prior to ablation, exclusion of left atrial appendage (LAA) thrombus is important. Whether ECG-gated dual-source computed tomography (DSCT) provides a sensitive means of detecting LAA thrombus in patients undergoing percutaneous AF ablation...

PurposeElectro-anatomic mapping (EAM) has been used for more than a decade to assist in defining arrhythmia propagation for transcatheter ablation. Intra-cardiac echocardiography (ICE) has also gained acceptance as an adjunct to further define intracardiac anatomy. The integration of these two technologies (CartoSound, Biosense-Webster, Diamond Bar...

IntroductionRecently, results describing pulmonary vein isolation (PVI) on patients using a robotic navigation system (RNS) in a high-volume center specialized in pulmonary vein isolation were published. The main purpose of this prospective study was to evaluate the learning curve of new users of RNS in a community hospital and to address the effec...

BackgroundAtrial septal defects (ASD), including patent foramen ovale, have been linked to an increased prevalence of migraine headaches in the general population. A similar association with migraine is speculated for iatrogenic ASD due to atrial septal puncture during catheter ablation for atrial fibrillation (AF).MethodsA total of 2,069 patients ...

PurposeModulation of the intrinsic cardiac autonomic nervous system (ICANS) has been described to occur during radiofrequency pulmonary vein (PV) isolation for paroxysmal atrial fibrillation (AF) and has been controversially proposed to increase clinical success. Energy source used for PV isolation might influence ICANS modulation. The effect of ba...
