Efficacy of Different Ablation Strategies for Controlling Atrial Fibrillation
Completed · Not applicable
Conditions studied: Atrial Fibrillation
In brief
This study involves treatment for atrial fibrillation (AF)-the most common heart condition in the US-where the upper chambers of the heart beat very fast and in a disorganized manner. This can be felt as palpitations, tiredness, shortness of breath and passing out, plus can lead to stroke, damage to the heart muscle and a shorter life span. Study participants will receive a common treatment for atrial fibrillation called radiofrequency ablation (RFA), where small lesions or "burns" are made inside the heart to cut off the abnormal impulses that cause AF. The purpose of this study is to compare the effectiveness of three different common ablation strategies in patients with persistent or permanent AF. Subjects will be randomized (like drawing straws) to be treated with one of the three strategies to see if there is a difference in how well atrial fibrillation is controlled after treatment.
