Abstract

The symptoms of myxomas depend on the size, mobility, and location of the tumor. A huge myxoma obstructing the tricuspid orifice can produce symptoms of tricuspid stenosis. In this case, a giant right atrial myxoma with intermittent tricuspid obliteration, presenting with clinical manifestations of right heart failure, is described. Three-dimensional reconstruction clearly identified the occlusive extent of the tricuspid orifice. (Echocardiography 2011;28:E183-E186)
