Abstract
A 68-year–old man with gastroesophageal reflux disease presented with chest tightness to the emergency department. He had undergone weight loss of 10 kg in the past 3 months. Physical examination revealed normal blood pressure, heart rate and temperature, but a wizened face and fine, brittle hair. Basic blood chemistry tests, chest radiograph, and ECG were unremarkable. Point-of-care ultrasonography with a modified apical 2-chamber view, 90 degrees counterclockwise from the apical 4-chamber position, revealed a dilated tube-like structure between the heart and descending aorta (Figure 1 and Video).
