Key result
Emergency aortic and mitral valve replacement led to rapid hemodynamic recovery and resolution of left-sided unilateral pulmonary edema caused by acute severe mitral regurgitation.
Why the study?
Unilateral cardiogenic pulmonary edema is rare, typically right-sided, and poses diagnostic challenges distinguishing it from pneumonia, often delaying corrective management.
Case Report (n=1)
No
This case highlights that acute severe mitral regurgitation can present as left-sided unilateral pulmonary edema, mimicking pneumonia, and requires prompt echocardiographic evaluation and surgical intervention.
May prompt consideration of left-sided UPE in acute severe MR; leaves open its true incidence and diagnostic algorithms.
Unilateral pulmonary edema (UPE) due to cardiac causes is an unusual clinical finding and typically emerges on the right side. UPE poses a diagnostic challenge due to difficulty distinguishing infiltrative pneumonia from cardiogenic edema on chest imaging. Consequently, corrective clinical management is significantly delayed in UPE compared to bilateral cardiogenic pulmonary edema. We present a very rare case of left-sided cardiogenic pulmonary edema due to acute severe MR wherein a prompt cardiac evaluation for UPE led to successful corrective surgery and favorable outcome.

Kang et al. (2022) conducted a case report in Acute mitral regurgitation with left dominant unilateral pulmonary edema (n=1). Emergency aortic and mitral valve replacement was evaluated on Clinical recovery. Emergency aortic and mitral valve replacement led to rapid hemodynamic recovery and resolution of left-sided unilateral pulmonary edema caused by acute severe mitral regurgitation.
