Why the study?
Does transesophageal echocardiography improve the diagnosis of acquired aneurysms of the left atrial appendage compared to transthoracic echocardiography?
Does transesophageal echocardiography improve the diagnosis of acquired aneurysms of the left atrial appendage compared to transthoracic echocardiography?
Transesophageal echocardiography is useful for accurately diagnosing left atrial appendage aneurysms that may be misdiagnosed as pericardial cysts by transthoracic echocardiography.
May differentiate LAA aneurysm from pericardial cyst misdiagnosed on TTE; leaves open the diagnostic utility of TEE in routine practice.
We report a patient with what appeared to be a pericardial cyst by transthoracic echocardiography but was, in effect, an aneurysm of the left atrial appendage as documented by transesophageal echocardiography.
