320-detector Computed Tomography to Assess Myocardial Extracellular Volume Fraction in Patients With Atrial Fibrillation Before AF Ablation.
This study explores the relationship between myocardial fibrosis and patient outcomes in Atrial Fibrillation (AF), specifically after catheter ablation. It aims to use Cardiac CT, an accessible tool, to measure left ventricular extracellular volume (ECV) as an indicator of fibrosis. The study will assess if higher ECV levels correlate with increased risks of AF recurrence, hospitalization, and poor cardiac function recovery. Positive findings could make ECV a key factor in deciding AF treatment strategies.
• Patients must be at least 21 years old at the time of enrollment.
• Patients must be able to give informed consent.
• Patients with symptomatic paroxysmal/persistent atrial fibrillation (AF).
• Eligible patients must be determined to be suitable candidates for ablation to treat AF by their cardiologist and/or electrophysiologists regardless of this protocol.
• Patients are scheduled to have a pre-procedure cardiac CT upon the discretion of their electrophysiologists
