Atrial fibrillation is the most common arrhythmia, with an increasing prevalence at higher age. Besides symptoms that affect quality of life, there is a significant risk of thromboembolic complications, heart failure and death. Different therapeutic options are proposed. Results of pharmacological treatment are often disappointing. Adverse side effects of antiarrhythmic medication are considera...

Atrial fibrillation (AF) is a multifactorial disease with complex pathophysiology. Although restoring sinus rhythm delays the progression of atrial remodeling, non-pharmacologic intervention, such as radiofrequency catheter ablation (RFCA), should be done based on the background pathophysiology of the disease. While circumferential pulmonary vein isolation (CPVI) has been known to be the corner...

Radiofrequency ablation has an important role in the management of post infarction ventricular tachycardia. The mapping and ablation of ventricular tachycardia (VT) is complex and technically challenging. In the era of implantable cardioverter defibrillators, the role of radiofrequency ablation is most commonly reserved as an adjunctive treatment for patients with frequent, symptomatic episodes...

approximately 25% of all oral cavity carcinomas involve the lips, and the primary management of these lesions is complete surgical resection. loss of tissue in the lips after resection is treated with a variety of techniques, depending on the extension and location of the defect. here we review highly accepted techniques of lip reconstruction and some of new trials with significant clinical res...

For cardiac surgery patients presenting with atrial fibrillation (AF), surgeons offer an operation that corrects the structural heart disease and the AF. With this approach, it is estimated that surgeons will perform more than 10,000 ablation procedures in 2007. Surgeons are developing minimally invasive techniques for stand-alone, epicardial ablation of AF. This article (1) reviews the rationa...

Introduction: The ablation technique is one of the important therapeutic interventions for treatment of AV Nodal tachyarrhythmia. Different animal models have been developed to study the effects of ablation on the functional interanodal structure. The aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbi...

Background: Local ablative treatments play an important role for patients who cannot be treated surgically. Radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. Microwave ablation (MWA) is a new minimally invasive treatment promising several improvements. The aim of this retrospective study was to evaluate the eff...

Atrial fibrillation (AF) is the most common arrhythmia in day to day practice. It contributes to morbidity in the form of heart failure and stroke and increased overall and cardiovascular mortality1. Moreover, no treatment of AF to date has resulted in a lower overall death rate. Anti arrhythmic therapy for AF may also contribute to increased mortality in this subgroup2. Even though AFFIRM inve...

WITH the increasing incidence of renal cell carcinoma (RCC) in the United States and the increasing proportion of patients with tumors detected at an early stage (1–5), nephron-sparing approaches are becoming more popular. These alternatives to radical nephrectomy include partial nephrectomy, wedge resection, and, more recently, in situ thermal ablation. Five-year survival rates after partial n...

INTRODUCTION The mechanisms for atrial fibrillation (AF) are unclear in part because diverse mapping techniques yield diverse maps, ranging from stable organized sources to highly disordered waves. We hypothesized that AF mechanisms may be clarified if mapping techniques were compared in the same patients, and referenced to a clinical endpoint. We compared two independent AF mapping techniques ...
