TEE - long-axis view of the left ventricle by the transgastric route. RV: right ventricle, LV: left ventricle. Patient mechanically ventilated because of ARDS secondary to pneumopathy. PEEP was 5 cmH2O, and plateau pressure was below 30 cmH2O. At each inspiration, two-dimensional mode coupled to motion mode visualizes dilatation of the right ventricle to the detriment of the left ventricle, which is flattened.
