Clinical Summary

This 21-year-old black male with sickle cell anemia had recurrent attacks of acute rheumatic fever beginning at age 14. Mitral insufficiencyAortic insufficiency refers to the inability of the aortic valve to close properly, thus allowing regurgitation of blood into the left ventricle during diastole -- i.e., volume overload. Disease of the aortic valve leaflets is a common cause of insufficiency. and stenosis were present by age 16. On prophylactic antibiotics, the patient had no evidence of recurrence until three weeks before his final admission, when an upper respiratory infection developed. A few weeks later he developed acute migratory polyarthritis. This was associated with rapid deterioration of cardiac function and death.

Autopsy Findings

At autopsy, the heart was enlarged--weighing 675 gramsA normal heart weighs 300 grams (range: 270 to 360 grams).--especially the left atrium. Both the aortic and mitral valves showed fibrosis as well as the fresh, tiny verrucae characteristic of acute rheumatic fever.
