To the Editor:— Dr. Gueft's suggestion is a very interesting one. However, I believe that my interpretation is more appropriate, for the following reasons: The patient was studied quite thoroughly several times at a cardiac surgery clinic for evaluation for aortic valve surgery and was diagnosed as having aortic insufficiency, apparently due to rheumatic heart disease. The appearance of the heart at autopsy, the marked endocarditic scarring of the aortic valve with fusion of the commissures, and the mild scarring of the mitral leaflets are characteristic of the changes seen in rheumatic heart disease. Neither the physicians at the cardiac clinic nor the men in our department found any features suggestive of Marfan's syndrome.
