title: [Assessment of the left atrial myxoma with gated blood pool SPECT].
abstract: A left atrial myxoma with 4 cm diameter was studied with ECG gated Tc-99m blood pool SPECT. The long axial images showed the myxoma to protrude through the mitral valve (MV) during diastole and to come back into the atrium in systole. No significant atrial dilatation due to the MV obstruction was detected. The ejection fraction calculated from the SPECT images was 10% lower than that of the conventional method viewed from LAO 45 degrees. Nuclear medicine gave an additional information for the assessment of the hemodynamics.
