Ablation of ventricular tachycardia (VT) by conventional radiofrequency ablation can be impossible if the ventricular wall at the targeted ablation site is very thick, as for example the ventricular septum. We present a case of a patient with incessant, non-sustained slow VT originating from the septal part of the lower outflow tracts. Radiofrequency catheter ablation from both ventricles as we...

INTRODUCTION Although rare, the atrioesophageal fistula is one of the most feared complications in radiofrequency catheter ablation of atrial fibrillation due to the high risk of mortality. OBJECTIVE This is a prospective controlled study, performed during regular radiofrequency catheter ablation of atrial fibrillation, to test whether esophageal displacement by handling the transesophageal e...

Pulmonary vein stenosis, which is one of the rare complications of radiofrequency catheter ablation for atrial fibrillation, has various symptoms. Here, we report a rare case of massive hemoptysis due to pulmonary vein stenosis following radiofrequency catheter ablation, which was successfully managed with pneumonectomy.

BACKGROUND Drug therapy is mostly employed in the management of supraventricular tachycardias (SVTs). However, radiofrequency catheter ablation has been found to be highly effective and safe in the treatment of SVTs. The current study is aimed at sharing our experience of 320 patients who presented with SVTs, and were treated with radiofrequency catheter ablation. METHODS This descriptive stu...

R adiofrequency catheter ablation of accessory pathways has been shown to be safe and effective, and is rapidly becoming the treatment of choice for patients with the Wolff-Parkinson-White syndrome or paroxysmal supraventricular tachycardia involving a concealed accessory pathway. l4 Because radiofrequency catheter ablation requires skill in mapping and catheter manipulation, the outcome is at ...

BACKGROUND Radiofrequency ablation inside pulmonary vein (PV) ostia can cause PV stenosis. A novel alternative method of ablation is irreversible electroporation, but the long-term response of PVs to electroporation ablation is unknown. METHODS AND RESULTS In ten 6-month-old pigs (60-75 kg), the response of PVs to circular electroporation and radiofrequency ablation was compared. Ten consecut...

Because of its high success rate and low morbidity, radiofrequency (RF) catheter ablation has become first line treatment for many arrhythmias. In this procedure, one or more electrode catheters are advanced percutaneously through the vasculature to contact cardiac tissues. A diagnostic study is performed to define the arrhythmia mechanism, and subsequently an ablation catheter is positioned ad...

Radiofrequency catheter ablation of accessory pathways and the atrioventricular junction often requires multiple applications of energy. The inability to determine the effects of any given application on the underlying tissue may contribute to this problem. In the present study, impedance was monitored in 20 patients undergoing radiofrequency catheter ablation, and the relationship between an i...

Pulmonary thromboembolism (PTE) is a fatal condition that may rarely occur due to complications of coronary catheter insertion. In this case report, a 41-year-old male was presented 48 hours after radiofrequency catheter ablation(RFCA) for the management of Wolf-Parkinson-White syndromewith acute onset of dyspnea, hemoptysis, and chest pain. The physical examination revealed coarse crackles in ...
