Reduction in pulmonary varix size after mitral valve replacement.

: A 48-year-old female was admitted to our hospital for examination of an abnormal shadow in the right lung field. She had a systolic murmur (4/6) over the apex and the chest radiograph revealed cardiac enlargement with three round opacities in the right lung field. Cardiac catheterization showed marked mitral regurgitation and large pulmonary varices. Pulmonary varix caused by mitral regurgitation was diagnosed. The size of the pulmonary varix was reduced with improvement of pulmonary artery wedge pressure one month after mitral valve replacement. We conclude that pulmonary varices can decrease in size secondary to lowering of left atrial pressure within one month after operation.
