[Wall calcifications of the left heart atrium].

The chest X-ray of a 61-year-old man with severe aortic and mitral stenosis revealed extensive, circularly arranged calcifications in the wall of the left atrial appendage. He died soon after admission to hospital and autopsy confirmed the atrial calcifications in association with severe mitral stenosis. Although such calcification of the left atrial wall is rare, it can be of importance because it may make the usual surgical approach to mitral valve replacement impossible.
