A 37 year old male with a history of peptic ulcer disease presented to the emergency room with nausea and vomiting. He reported two recent episodes of syncope, but denied other associated symptoms including palpitations, hematemesis, melena, chest pain, or dyspnea. He reported recent use of marijuana, but denied use of cocaine or methamphetamines. The patient reported similar symptoms in 2006 w...

OBJECTIVES The purpose of this study was to determine the efficacy and risks of radiofrequency ablation of various forms of supraventricular tachycardia after Mustard and Senning operations for d-transposition of the great arteries. BACKGROUND In this patient group, the reported success rate of catheter ablation of intraatrial reentry tachycardia is about 70% with a negligible complication ra...

Radiofrequency catheter ablation (RFCA) has recently become a management option for pediatric tachycardia. We reviewed the records of a total of 100 patients (aged 10 months to 19 yr) who had undergone RFCA, from March 2000 to June 2004. Types of arrhythmia (age, acute success rate) were as follows: atrioventricular reentrant tachycardia (AVRT, 9.0+/-3.7 yr, 66/67), atrioventricular nodal reent...

INTRODUCTION AND OBJECTIVES Nodal slow pathway ablation is the treatment of choice for nodal reentrant tachycardia. No demographic, anatomic, or electrophysiologic variables have been reported to predict an exact location of the slow pathway in the atrioventricular node or its proximity to the fast pathway. The purpose of this study was to analyze these variables. METHODS The study prospectiv...

PURPOSE OF REVIEW The purpose of the review is to provide an update on the safety and efficacy of catheter cryoablation. RECENT FINDINGS Catheter cryoablation is a safe and clinically effective method for ablation of atrioventricular nodal reentrant supraventricular tachycardia. Although the acute procedural success rate of catheter cryoablation for this arrhythmia may be slightly lower than ...
