Multimodality imaging of giant prolapsing left atrial myxoma.

Through a case of a very large left atrial myxoma diagnosed in a 53-year old woman, we feature the complementary value of multimodality imaging. Two-dimensional echocardiography continues to be the principal imaging modality for intracardiac masses due to its accessibility and ability to provide basic information on mass morphology, position, and mobility. Real-time three-dimensional echocardiography offers more precise assessment of tumor size and attachment.
