Unilateral pulmonary edema represents only 2% of cardiogenic pulmonary edema with predilection for the right upper lobe and is strongly associated with severe mitral regurgitation 1,2. It is hypothesized that the regurgitation jet is directed towards the right superior pulmonary vein thus preferentially increasing the hydrostatic pressure in the right upper lobe 3.
