Brief summary (registry, in English)
This study will assess how two different ablation strategies, using two different ablation catheters during catheter ablation for paroxysmal atrial fibrillation, affect the temperature of the esophagus during ablation, and the risk of injury to the esophagus.

Built from the registry fields of ClinicalTrials.gov. It describes the study, not your situation.
Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Patients who have undergone prior left atrial ablation procedures.
Other illness
- Patients who have contraindications to capsule endoscopy, or GI conditions that may increase the risks of capsule endoscopy (e.g. esophageal strictures, inflammatory bowel disease, etc)
Other
- Patients where the use of the Q-DOT Micro ablation catheter in QMODE+ (i.e. temperature-controlled very-high-power short-duration ablation) is felt to be unsafe.
- Any records flagged "break the glass" or "research opt out."
Who the study is looking for
- Provision of signed and dated informed consent form
- Stated willingness to comply with all study procedures and availability for the duration of the study
- Male or female, aged greater than or equal to 18 years
- Diagnosed with paroxysmal atrial fibrillation
- Undergoing RF catheter ablation for treatment of paroxysmal atrial fibrillation that will involve circumferential point-by-point radiofrequency ablation pulmonary vein isolation with no additional left atrial posterior wall ablation planned
Age in the registry: 18 years to - · Sex: All · Does not accept healthy volunteers
