title: [Right atrial thrombus recognized 18 years after tricuspid valve replacement: a case report].
abstract: A 53-year-old man, who had undergone tricuspid valve replacement with Hancock valve and direct closure of a ventricular septal defect when aged 34 years, was admitted with signs of right heart failure. Two-dimensional echocardiography showed bioprosthetic tricuspid valve malfunction with right atrial thrombus. He was treated by tricuspid valve replacement using a Hancock II valve and removal of the right atrial thrombus with remarkable improvement. Transesophageal echocardiography was the most useful method for recognizing the presence of right atrial thrombus and assessing its actual or potential hemodynamic effects.
