Fig. 171.— Ulceration of the anterior segment of the mitral valve; enormovs hypertrophy and dilatationof the left ventricle; the acrlic valve was also tdcerated and hir/hly incompetent. (^Considerablyless than tkeacltcal preparation which is in the Anatomical Museum of the Edinburgh University.) The anterior eegment of the mitral valve has been turned upwards to show the ventricularsurface of the valve. A piece of whalebone is inserted in the perforation. The ventricle lias been opeued from behind, and its walls are kept apart by a piece of auricular surface of the ulcerated valve is seen in fig. 170.

The aortic segments, the ven-tricular surface of the mitral valve and the chordae tendineae,are also more often found diseased than in simple rheumaticendocarditis. The
