B) Top right, Continuous wave Doppler through the mitral valve in the four chamber apical view: This image shows significant (> 30%) respiratory variation in mitral inflow velocity. C) Bottom, Subcostal view: There is a large circumferential pericardial effusion with visible partial collapse of the right ventricle and right atrium.
