We describe a patient with syncope associated with swallowing. This syncope was caused by transient compression of the left atrium (LA) by an esophageal hiatal hernia. Two‐dimensional echocardiography demonstrated a hyperechoic mass compressing the LA from the posterior. With air insufflation of the esophagus, compression of the LA by this hernia sac was seen to increase. Pulsed and color Doppler echocardiography revealed greatly decreased velocity of blood flowing into the LA and left ventricle (LV). Thus, marked compression of the LA by an esophageal hiatal hernia can cause syncope by impeding blood flow from the LA to the LV. Echocardiography proved highly useful in diagnosis.
