Right atrial-esophageal fistula and hydropneumopericardium after esophageal dilation

Esophagoatrial fistula formation is a rare and heretofore fatal event. A patient presented with esophageal reflux and stricture that later developed into a right atrial-esophageal fistula during biweekly esophageal dilation. Clinical recognition and surgical therapy led to a successful outcome. There were several unique features of this case, including fistulous connection to the right rather than the left atrium, concomitant hydropneumopericardium and esophagoatrial fistula, occurrence during esophageal dilation and surgical cure.
