Outcome Measures

Primary Outcomes (4)

  • Temperature Decline

    I. To determine the correlation between rate of temperature decline and nadir cryoballoon temperatures rate of temperature decline and nadir esophageal temperatures during pulmonary vein isolation procedure.

    90 days or when complications resolve

  • Measurements of esophagus to each pulmonary vein

    II. To accurately measure the distance between the esophagus and the ostium of each pulmonary vein intra-operatively.

    90 days or when complications resolve

  • Create Recommendations for esophageal temperature-guided ablation

    To attempt to create recommendations for esophageal temperature-guided ablation in order to increase the safety profile of cryoballoon pulmonary vein isolation (PVI) by providing one center's experience. By trending cryoballoon ablation temperatures and subsequent esophageal temperatures, data trends may emerge and be predictive for esophageal ulceration formation. These trends may include: * Distance between esophagus and pulmonary vein in patients who developed post-ablation esophageal ulcerations * Intra-procedure esophageal temperatures in patients who developed post-ablation esophageal ulcerations * Intra-procedure cryoballoon temperatures in patients who developed post-ablation esophageal ulcerations

    90 days or when complications resolve

  • Assessment of additional Adverse Events

    To associate the development of symptoms (including dysphagia, chest pain, fever, "heartburn," or odynophagia) with the presence of ulcerations.

    90 days or when complications resolve

Secondary Outcomes (1)

  • Data collection on Phrenic Injury

    90 days or when complications resolve

Procedure: Esophageal Temperature-Guided Ablation

Interventions

Esophageal temperature-guided ablation (if esophageal temperatures drop too low during cryoablation, the physician will stop the ablation) in order to increase the safety profile of cryoballoon pulmonary vein (a vein carrying blood from the participants lungs to the left side of the participants heart known as the left atrium) isolation (PVI \[means a balloon shaped catheter will be placed at the opening of each pulmonary vein and tissue will be cooled in order to create an ablation line (line of scar tissue) between the left side of the participants heart and each pulmonary vein. This is done to prevent the triggers that typically cause intermittent atrial fibrillation (known as Paroxsymal Atrial Fibrillation) by providing one center's experience.
