CONTEXT Antiarrhythmic drugs are commonly used for prevention of recurrent atrial fibrillation (AF) despite inconsistent efficacy and frequent adverse effects. Catheter ablation has been proposed as an alternative treatment for paroxysmal AF. OBJECTIVE To determine the efficacy of catheter ablation compared with antiarrhythmic drug therapy (ADT) in treating symptomatic paroxysmal AF. DESIGN...

Background: Energy deficit is a common and serious problem in pediatric intensive care units. Parenteral nutrition, either alone or in combination with enteral nutrition, can improve nutrient delivery in critically ill patients by preventing or correcting the energy deficit and improving the outcomes. Intralipid 10% and 20% are lipid emulsions, widely used in parenteral nutrition. Despite sever...

An increase in cardiac radiofrequency catheter ablation for treating refractory atrial fibrillation has resulted in an increased prevalence of complications. Among numerous complications of radiofrequency catheter ablation, atrio-esophageal fistula, although rare, is known to have fatal results. We report a case of successful management of an atrio-esophageal fistula as a complication of cardia...

Five patients with chronic or recurrent ectopic supraventricular tachycardias unresponsive to drugs underwent programmed stimulation, endocardial mapping, and attempted catheter ablation of the arrhythmia focus. For attempted ablation, an intracardiac electrode catheter was positioned near the exit point of the tachycardia and served as the cathode while a chest wall patch served as the anode. ...

BACKGROUND In patients with mechanical aortic and mitral valves and left ventricular tachycardia, catheter ablation may be prevented by limited access to the left ventricle. METHODS AND RESULTS In our series of 6 patients, 2 patients underwent direct surgical ablation and 4 underwent epicardial catheter ablation via a pericardial window. All patients had abnormal low voltage areas with fracti...

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 ...

Isochronal late activation mapping (ILAM) is a well-established method for ventricular arrhythmias. However, the role of ILAM during atrial arrhythmias less clear. This case provides an example use right flutter ablation using high-density Optrell (Biosense Webster, CARTO) catheter in patient with congenital heart disease. N/A A 27-year-old female D-transposition great arteries status post Nika...

A 19-year-old female underwent repair of complex congenital heart disease (atrial and ventricular septal defect with a supero-inferior ventricular relationship) in infancy. Because of recurrent palpitations she underwent an electrophysiology study. Atypical atrioventricular nodal reentrant tachycardia was diagnosed. Catheter ablation was performed successfully using cryothermal energy. The diag...

conclusions the accompanying case series suggests that this protocol is deserving of randomized, prospective study. results c-rfa of the genicular nerves after using the described selection protocol resulted in > 90% pain reduction, improved function and avoidance of surgery at 6 months in all four cases. all opioid and analgesic medication use decreased or was unchanged in all cases. no seriou...

Introduction Percutaneous catheter ablation is an established rhythm control strategy for the treatment of atrial fibrillation (AF). Recent clinical trials show that catheter ablation of atrial fibrillation reduces the risk of recurrence of symptomatic AF, atrial flutter, or atrial tachycardia, and may also reduce subsequent hospitalizations and improve quality of life compared to antiarrhythmi...
