Poster 91: Ayesha Khan – A Comparison of Cryoballoon Ablation Techniques For Atrial Fibrillation Treatment

<< Return to the Virtual URS Main Page

Faculty mentor: Ravi Ranjan

Cryothermal ablation techniques were compared in regard to treatment of Atrial Fibrillation (AFib). AFib is the most common sustained cardiac arrhythmia in the U.S. and the most common cause of fatal cardiac diseases. Successful ablation is measure by the isolation or amount of chronic scar created around pulmonary veins in the left atrium. Two ablation techniques were compared: freeze-thaw-freeze and single freeze. LGE-MRIs of 25 human patients were analyzed to compare both ablative methods.
