What structure is at risk during a left atrial ablation?
Esophagus, remember that the left atrium is the most posterior part of the heart and is in close contact with the esophagus
Development of extensive air scattered throughout the brain. This is likely air emboli secondary to an atrio-esophageal fistula. Poor grey-white matter differentiation and loss of sulci suggesting diffuse cerebral edema, ischemia, and/or infarction.
