Transmitted cardiovascular pulsations on high resolution esophageal impedance manometry, and their significance in dysphagia

Figure 4 In one of the patients with enlarged left atrium, bolus clearance was 80% in supine swallows and 10 % upright. A: Pulsatile pressure zone with impaired bolus clearance easily visible in a dysphagia patient in upright posture due to left atrial enlargement; B: Corresponding CT Scan Images of the same patient (Left) Esophagus patent in upper thorax (Right) Esophagus compressed between dilated left atrium (LA) and descending aorta (Ao).
