Background Atrial fibrillation (AF) is the most common cardiac arrhythmia affecting more than 2 million people in North America. Radio-frequency (RF) and cryo ablations of the left atrium (LA) are effective for symptomatic, drug refractory AF patients. Reported success rates of the procedure vary significantly with AF recurrences ranging from 25-50%. Many AF recurrences occur early after the pr...

Radio-frequency (RF) catheter ablation has become the standard treatment of atrial fibrillation if pharmacotherapy fails. As an alternative to traditional RF standard ablation catheters, single-shot devices have received more and more interest. One group of these devices are cryo-balloon catheters. Such catheters are designed to electrically isolate a pulmonary vein (PV) with only a few applica...

Background Radiofrequency ablation of varicose vein have gained popularity compared to conventional surgery due to comparable long term results in addition to definite immediate superiorities. This modality has been started in Nepal since August 2003 and the study on short term fate of ablated vein segment confirms the anatomical benefit in addition to the clinical benefit.
