Why the study?
Does transesophageal echocardiography improve diagnostic accuracy compared to transthoracic echocardiography in a patient with mitral valve myxoma?
Does transesophageal echocardiography improve diagnostic accuracy compared to transthoracic echocardiography in a patient with mitral valve myxoma?
Transesophageal echocardiography is superior to transthoracic echocardiography for accurately diagnosing and characterizing rare mitral valve myxomas.
May clarify mitral valve myxoma anatomy when transthoracic findings are equivocal; leaves open need for prospective validation.
Mitral valve myxomas are rare. We report a patient with a mitral myxoma arising from the posterior mitral leaflet in whom transthoracic echocardiography revealed equivocal findings. However, transoesophageal echocardiography provided accurate relevant anatomical information including the size, morphological characteristics, and tumour attachment point.
