Nineteen procedures were performed in 17 children, aged 10 months to 17 years, using catheter radiofrequency applications for the management of malignant or drug-resistant supraventricular tachyarrhythmias. Diagnoses were junctional ectopic tachycardia in 1 patient, atrioventricular (AV) node reentrant tachycardia in 4 and accessory pathway-mediated tachycardia in 12. Accessory pathway location...

Radiofrequency catheter ablation (RFCA) is the treatment of choice for cardiac arrhythmias. However, sometimes, RFCA may be insufficient to eliminate the arrhythmias. Arrhythmic foci that are deep seated in the myocardium may not be amenable to catheter ablation from either the endocardium or the epicardium. Catheter ablation may also fail to produce a complete lesion and there can be surviving...

Background: Radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) in patients with prosthetic valve is still a challenge because the higher recurrence rate and difficult manipulation catheters left atrium which may lead to risk complications. We presented first AF Vietnam patient who had mitral aortic mechanical valves.
 Case summary:
 A 54-year-old man two heart valves ...

We report a case of successful radiofrequency catheter ablation in a patient with dilated cardiomyopathy, who presented with multiple, haemodynamically poorly tolerated episodes of monomorphic ventricular tachycardia, resistant to antiarrhythmic drug treatment. The ablation procedure consisted of focal ablation of three mapped left ventricular sites, using pace and activation mapping. Additiona...

Phrenic nerve palsy has been recognized as a complication of catheter ablation with a prevalence of 0.11-0.48% after atrial fibrillation ablation, independent of the type of ablation catheter or energy source, likely due to the anatomical relationship of the nerves. This report describes a case of new onset of shortness of breath (SOB) due to left diaphragm paralysis following transcatheter rad...

BACKGROUND Catheter ablation of accessory atrioventricular (AV) connections has been demonstrated to be effective in more than 85% of patients. One of the risks of this procedure is radiation exposure during the fluoroscopic imaging necessary to guide catheter manipulation. The objective of the present study was to measure the radiation received by patients and physicians during radiofrequency ...

Background: The clinical effectiveness and efficiency of a steerable sheath for radiofrequency catheter ablation (RFCA) in Chinese patients with atrial fibrillation (AF) needs to be compared fixed curve optimize RFCA procedure.

BACKGROUND Radiofrequency catheter ablation for paroxysmal atrial fibrillation is well established but not drawback free. Pulmonary vein stenosis is one of the complications and usually treated with stenting with the disadvantages of high re-stenosis rate and anticoagulant dependence. CASE PRESENTATION Herein, we present the case of a 47 year-old lady, who suffered from fever and hemoptysis d...

Pulmonary vein ablation with a single-tip catheter remains long and complex. We describe a typical case of a novel efficient technique with a decapolar ring catheter utilizing alternating unipolar/bipolar radiofrequency energy. Voltage analysis and electrical mapping demonstrate the potential for antrum ablation and pulmonary vein isolation.
