Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
OFDI Capsule Imaging
Arm Description
Subject will swallow the OFDI capsule and imaging will be acquired using the OFDI Imaging system.
Outcomes
Primary Outcome Measures
Feasibility of a Tethered OFDI Capsule in Patients With Atrial Fibrillation Following RF Ablation That Swallow the OFDI Capsule
An investigator will assess the quality of the recorded images and movies obtained with each exam after the imaging is completed. A total of 6 subjects were enrolled in this study. 1 participant was not analyzed as they could not attempt to swallow the capsule.

5. Study Description
Brief Summary
12 patients with Atrial Fibrillation, a kind of irregular heart beat who have undergone Radio frequency (RF) ablation will be asked to swallow the capsule.
As they swallow the capsule, images of the esophagus will be taken to see if the RF ablation caused any form of damage to the esophagus considering it being so close to the heart.
After the capsule has been removed from the mouth, they will be asked about the tolerability of the capsule.
Detailed Description
A total of 12 patients with a known diagnosis of Atrial Fibrillation who have previously undergone Atrial RF ablation will be enrolled in the study. Patients will be asked to swallow the OFDI capsule while being unsedated. The capsule is attached to a tether that allows the capsule operator to navigate the capsule as it progresses down the esophagus using natural propulsion called peristalsis as well as to bring it back up to pulled out of the mouth when the procedure is done.
As the capsule progresses down the esophagus, multiple, two dimensional, microscopic cross- sectional images of the esophagus are acquired.
