There is very little translation of the lateral wall, but it shows good thickening during systole.  By comparison, the is excessive translation of the septum.  On both the thallium and the sestamibi raw data there is a paucity of activity over the left chest.  The attenuation data show that the left chest has fluid density.

• The patient had a prior left pneumonectomy.  The lateral wall of the left ventricle is fixed in position.  With systole, the ventricle translates laterally.  The lateral wall is contracting, but it does not move; consequently the septum has exaggerated motion.
• Also of note, the right ventricle is prominent on SPECT data.  Echocardiography showed elevated pulmonary artery pressure.
