HEART - Mitral stenosis

This is a very old specimen. The aortic and tricuspid valves appear normal. The left auricular wall is hypertrophied and the endocardium thickened. There is fusion of the mitral valve cusps resulting in a small crescentic opening. There is irregular calcification in both the cusps. On the posterior aspect thickening of the chordae can be discerned and there is both left and right ventricular hypertrophy.
