Abstract
A 74-year-old woman who had paroxysmal atrial fibrillation without
mitral stenosis was hospitalized for syncope and right-sided
weakness. Echocardiography revealed a large free-floating thrombus
in the left atrium, sometimes prolapsing partially into the left ventricle
in diastole. Because of her poor neurological status, she was managed
with anticoagulation. On the 12th day, the thrombus had disappeared
on the follow-up echocardiography, and aortoiliac embolization was
later detected on computed tomography. Unfortunately, she developed
various complications of stroke and limb infarction, and died after 4
months of hospital care. In addition to this case report, we reviewed a
total 70 cases of left atrial free-floating thrombus. Atrial fibrillation
and mitral pathology were two major causative factors. All the cases,
except 1, were confirmed on echocardiography. The most common
presentation that led to echocardiography was systemic embolization,
followed by heart failure. Others were acute hemodynamic
decompensation from mitral obstruction, chest pain, palpitation, and
bacteremia. Cardiac thrombectomy was the preferred treatment
modality with favorable outcomes.
