    Abstract:
    A 57-year-old man was admitted with dyspnea and bloody sputum. The chest X-ray showed unilateral alveolar infiltration, and alveolar cell carcinoma was suspected. Physical examination showed orthopnea and a loud systolic murmur, and the echocardiogram showed mitral valve prolapse. A chest X-ray 4 days later revealed bilateral infiltration. The cardiac catheterization showed pulmonary congestion and the capillary wedge pressure revealed a prominent V wave. Papanicolaou's test of sputum was negative. These findings suggested heart failure due to mitral regurgitation rather than lung carcinoma. The patient underwent mitral valve replacement because of his refractoriness to the medical treatment. During the operation, the chordae tendineae of the anterior mitral leaflet was found to be completely ruptured. The mechanisms of unilateral pulmonary edema could not be ascertained, but the effect of posture and gravity was thought to be a possible mechanism.
