Left arterial aneurysms refer to rare focal outpouchings arising from the left atrium. They can be congenital or acquired. Congenital left atrial aneurysms can be further divided into intra- and extra-pericardial types.
Clinical presentation
Patients may be asymptomatic or present with atrial tachyarrhythmias.
Complications
May lead to atrial tachyarrhythmia or thromboembolic events.
Treatment and prognosis
Resection and mitral valvuloplasty is often recommended as the treatment of choice.
