Subacute bacterial endocarditis had been suspected but excluded by blood cultures. At 15 weeks she first applied for care and was admitted to the hospital because of congestive heart failure after very slight exertion, presenting Grade 4 systolic and Grade 3 diastolic aortic murmurs loud enough to obscure any other sounds. . . .
