In the Sept 8 issue of The Journal (240:1139, 1978), the LETTER TO THE EDITOR entitled "Dysphagia From Thoracic Ankylotic Spur" incorrectly identified the chamber of the heart impinging on the anterior aspect of the esophagus as the right atrium (column 2, line 9). The posterior border of the heart in this region is formed by the left, not the right, atrium.
