Details and patient eligibility

About

The purpose of this study is to assess whether normal endothelial function in patients with Atrial Fibrillation undergoing ablation procedure increases the chances of a favorable clinical outcome and maintaining sinus rhythm following ablation

Full description

In the recent years, increasing evidence is linking inflammation to AFib. In addition, it has been shown that ablation improves endothelial function, suggesting that AFib might be associated with the etiology of endothelial dysfunction.

The objective of this study is to assess endothelial function using Endo-PAT2000 and its correlation to clinical outcome following ablation of patients with Atrial Fibrillation (AFib).

Enrollment: 150 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• All patients with AF considered eligible for ablation treatment may be included in this study (following unsuccessful attempts with AAD).

Exclusion criteria

• Patients age below 18 years
• Cases with extremely abnormal anatomy (i.e., inverted heart)
• Moderate or severe mitral valve disease or mitral prosthetic valve
• Ejection fraction less than 30%
• Left atrial anteroposterior diameter more than 50 mm evaluated by echo or CT data (up to 6 months old)..
• Previous atrial fibrillation ablation occurred less than 6 months prior
