Right heart thrombi are rare but potentially life-threatening complications of acute pulmonary embolism.
We report the case of a 57-year-old hemodynamically stable woman with pulmonary embolism and a large free-floating right atrial thrombus associated with right ventricular dilatation and systolic dysfunction. Anticoagulation with enoxaparin followed by apixaban led to complete thrombus resolution within 10 days, with regression of right ventricular dilatation and recovery of systolic function.
This case suggests that anticoagulation alone may be effective in carefully selected hemodynamically stable patients, although the optimal management of right heart thrombi remains controversial. Early echocardiographic diagnosis and individualized treatment are essential.
