Clinical Summary[edit]

This 21-year-old black male with sickle cell anemia had recurrent attacks of acute rheumatic fever beginning at age 14. Mitral 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.

Aortic 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.

Friable material is easily crumbled.

Autoimmune disorders involve an immune response directed at the host's own cells.
