Abstract
Free-floating thrombi in the right atrium (RA) are extremely hazardous to patients with pulmonary thromboembolism, and optimal treatment methods remain unclear. We report a case of successful percutaneous intervention of a critical right atrial thrombus. The patient was a 50-year-old woman who had been under medication for acute myocarditis when she complained of sudden severe dyspnea. Echocardiography showed a mobile snake-like thrombus in the RA. The thrombus was pulled back to the distal inferior vena cava (IVC) using a catheter and an IVC filter was placed. Percutaneous treatment is useful for treating free-floating RA thrombi.
