Background: Malignant biliary and/or pancreatic obstruction has often encountered in the advanced stages of periampullary and cholangicarcinomas. HabibTM Radiofrequency (RF) ablation has been successfully used in the management of various cancers of liver and pancreas. Percutaneous HPB probe (EMcision Ltd, London, UK) is a new addition to this class of tools. It is an endoluminal Radiofrequency...
Prosthetic valves may make ventricular access difficult in radiofrequency catheter ablation. This case report describes an optimized atrial transseptal approach to access the ventricle in a patient with left ventricular tachycardia and a mechanical prosthetic aortic valve.
This case report describes a patient with the permanent form of junctional reciprocating tachycardia coexisting with atrial tachycardia. A detailed electrophysiological study established the diagnosis, and radiofrequency catheter ablation abolished both arrythmias.
INTRODUCTION During radiofrequency ablation to encircle or isolate the pulmonary veins (PVs), applications of radiofrequency energy within a PV may result in stenosis. The aim of this study was to determine whether monitoring of real-time impedance facilitates detection of inadvertent catheter movement into a PV. METHODS AND RESULTS In 30 consecutive patients (mean age 53 +/- 11 years) who un...
The popping phenomenon during radiofrequency catheter ablation is well known to experienced electrophysiologists. When the electrode-tissue interface temperature increases rapidly above the boiling point, it can vaporize blood, thus causing a mini-explosion and an audible pop. Evaporation may occur intramurally, leading to gas bubble formation within the tissue. With continued energy applicatio...
OBJECTIVES To evaluate if radiofrequency catheter ablation is an effective procedure for the treatment of right ventricular outflow tract premature ventricular contractions (RVOT-PVC) and ascertain if it results in an improvement of symptoms. METHODS A prospective study with 30 consecutive patients (mean age 40 +/- 13 years, 25 females), with no apparent structural cardiopathy, with very freq...
BACKGROUND Current guidelines recommend pulmonary-vein isolation by means of catheter ablation as treatment for drug-refractory paroxysmal atrial fibrillation. Radiofrequency ablation is the most common method, and cryoballoon ablation is the second most frequently used technology. METHODS We conducted a multicenter, randomized trial to determine whether cryoballoon ablation was noninferior t...
