Over the past 5 years, the electrophysiology community has been focused on the development of catheter ablation techniques and ablation systems to cure atrial fibrillation. This endeavour has been fuelled by a number of factors including: (1) the clinical importance of atrial fibrillation because of its high prevalence in the general population, associated symptoms, stroke risk, and increased m...

Percutenous catheter ablation of the accessory pathway in Wolff-Parkinson-White syndrome is a highly successful mode of therapy. Sudden cardiac arrest survivors associated with WPW syndrome should undergo radiofrequency catheter ablation. WPW syndrome associated with familial atrial fibrillation is a very rare condition. Herein, we describe a case who presented with sudden cardiac arrest second...

Catheter ablation of drug-refractory ventricular tachycardia (VT) that occurs in infancy can be challenging owing to the small size of the heart and vessels compared to the ablation catheters. We present a toddler with incessant left ventricular (LV) tachycardia that was successfully treated by radiofrequency catheter ablation with an 8 French irrigated-tip catheter via a transapical approach. ...

Occurrence of ventricular tachycardia (VT) remains a risk in repaired congenital heart disease (CHD).1-3) We report a case of successful catheter ablation of drug-refractory peri-conduit VT in a patient with Rastelli-type repair using a right ventricle-to-pulmonary artery (RV-PA) conduit. Electroanatomic activation and voltage maps of the RV were created and merged with cardiac CT using the CAR...

Supraventricular arrhythmias are a frequent complication in adults with congenital heart disease (ACHD). The prevalence increases with time since surgery, complexity of the underlying defect, type of repair and older age at surgery. Arrhythmias are the most frequent reason for hospital admission and along with heart failure the leading cause of death. The arrhythmia-associated increase in morbi...

conclusions the incidence of liver abscesses after liver cancer thermal ablation is low. child-pugh class b and class c cirrhosis, biliary tract disease, diabetes mellitus, and porta hepatis tumors are four significant risk factors. combined ablation and pei reduces the rate of liver abscesses. background radiofrequency ablation (rfa) and microwave ablation (mwa) are the most frequently used th...

The advent of electrophysiology (EP) testing revolutionized the care of children with arrhythmia. Precise mechanistic and anatomical diagnosis of arrhythmias became possible. The later development of catheter-based ablation transformed the care of these children by allowing many arrhythmias to be cured during the same procedure. Indications for EP testing vary depending on the age of the child,...

it has been well - established that common atrial flutter is due to intraatrial macroreentry and its reentry circuit locates in the right atrium. this reentry circuit has been characterized to involve an area of slow conduction identifiable electrophysiologically at the low posteroseptal right atrium and anatomical narrow isthmus snrrounded by the inferior vena capa, coronary sinus astium and t...

AF ablation can be curative or reduce the symptoms of AF. However, success rates are suboptimal while procedure times can be long. Since AF ablation depends on excellent tip to tissue contact, ease of use and signal quality, a new ablation catheter (FlexAbilityTM Ablation Catheter, St Jude Medical, St Paul, MN) was designed for use during complex ablation. We report an initial case of its use d...

OBJECTIVES To study the impact of contact force (CF) sensing on fluoroscopy, procedure, left atrial (LA) and ablation times and number of ablations during atrial fibrillation (AF) ablation. BACKGROUND Catheter ablation is an effective treatment for symptomatic AF. Recently a new ablation catheter providing real-time CF has been approved for use. METHODS A nested case-control study was perfo...
