Atrial Fibrillation
Atrial Defibrillation: A New Treatment for Atrial Fibrillation How Do We Best Manage These Patients?
Atrial fibrillation (AF) affects over 3.3 million Americans, and 5 million people worldwide. Patients with atrial fibrillation often have associated symptoms such as heart palpitations, fatigue, dizziness, shortness of breath, and/or pressure or discomfort in the chest. It may also cause more serious complications such as syncope, stroke, or heart failure. Atrial fibrillation can interrupt patients work schedules, social functions and other daily activities.
Right Atrial Ablation in the Management of Atrial Fibrillation: Point of View
AF is characterized by uncoordinated atrial activation with consequent deterioration of atrial mechanical function.4 Thromboembolic disease and ischemic stroke are the most important complications of AF, and their occurrence is increased in both paroxysmal (intermittent) and chronic forms of AF.3 The rate of ischemic stroke among patients with nonrheumatic AF averages 5% per year, which is 2-7 times the rate for individuals without AF.4 One of every six strokes occurs in patients with AF.4 In the Framingham Heart Study, patients with rheumatic heart disease and AF had a striking 17-fold increased risk of stroke compared to age-matched controls.5 Most importantly, ischemic stroke associated with AF is nearly twice as likely to be fatal as non-AF stroke.5 In addition, stroke recurrence is more frequent and functional deficits following an AF-related stroke are more likely to be severe with persisting neurological de

Treating Atrial Fibrillation: What's Next?: Commentary: Looking at the Future Treating Atrial Fibrillation
During the past few years, several approaches have been introduced in an attempt to maintain sinus rhythm in symptomatic patients with atrial fibrillation (AF). New developments are certainly dependent on acquisition of new knowledge and on technological advances.
At the present time, two main basic concepts govern our therapeutic approaches. First, triggers proceeding from the pulmonary veins frequently initiate AF. Second, once initiated a critical mass of atrium is required to maintain this arrhythmia. Hence, current ablation strategy in patients with paroxysmal AF is to isolate the triggers by eliminating conduction from the pulmonary veins into the left atrium. Linear atrial lesions are added to pulmonary vein isolation in patients with persistent AF in an attempt to eliminate the critical mass of atrium required to support the arrhythmia.
