RIGHT ATRIAL MURAL THROMBUS ASSOCIATED WITH PERICARDITIS

A 33-year-old man was hospitalized with right heart failure. He was di agnosed as having right atrial mural thrombus complicated with pericar ditis on echocardiography, thoracic computed tomography, and cardiac c atheterization. Pericardiectomy and thrombectomy with a partial resect ion of the right atrial wall were performed under extracorporeal circu lation. It was suggested that the cause of right atrial thrombus was c ongestion, atrial fibrillation, and pericarditis. The cause of pericar ditis could not be determined by pathologic examination and laboratory data. Surgical treatment should be performed as soon as possible to p revent pulmonary embolism.
