Abstract
Background Myxomas are the most common primary cardiac tumor in adults and are most commonly
found within the left atrium. These are usually asymptomatic, detected incidentally,
or present gradually with symptoms typical of heart failure.
Case Description This case report is a description of a case of syncope caused by a large left atrial
myxoma.
Conclusion Atrial myxomas may present with transient loss of consciousness, especially when
they prolapse through the atrioventricular valves or when embolization occurs. Non-invasive
diagnostic tools (e.g., echocardiogram, cardiac computed tomography) should be considered
to thoroughly evaluate cardiogenic causes of syncope.
