However, cardiogenic unilateral pulmonary edema is a rare yet important entity that is often misdiagnosed initially, leading to significant delays in treatment. Cardiogenic unilateral pulmonary edema is often secondary to acute mitral regurgitation (MR), a life-threatening hemodynamic abnormality that requires urgent medical attention and usually surgical intervention. Acute posterior leaflet flail has been associated with right-sided unilateral pulmonary edema. However, anterior leaflet flail leading to right upper lobe opacity is very rare.
