Key result
Echocardiography diagnoses syncope caused by a hiatal hernia compressing the LA and impeding LV inflow.
Why the study?
Syncope associated with swallowing caused by transient compression of the left atrium by an esophageal hiatal hernia is a rare and diagnostically challenging condition.

Echocardiography may identify rare mechanical syncope causes; leaves open prevalence and management impact beyond case reports.
Case Report (n=1)
Echocardiography is a highly useful diagnostic tool for identifying rare mechanical causes of syncope, such as left atrial compression by an esophageal hiatal hernia.
Oishi et al. (2004) conducted a case report in Syncope associated with swallowing (n=1). Echocardiography was evaluated. Marked compression of the left atrium by an esophageal hiatal hernia caused syncope by impeding blood flow to the left ventricle, which was successfully diagnosed using echocardiography.
