RESUMO
This report describes the course and operative findings in a 66-year-old man with a densely calcified false aneurysm of his ascending aorta 19 years after replacement of a severely stenosed bicuspid aortic valve with a McGovern-Chromie prosthesis. This report emphasizes the need to consider this possibility, even in patients with a very remote prior operation.

US military recruits receive benzathine penicillin prophylaxis because of endemicity of group A beta-hemolytic streptococcal (GABHS) infections. GABHS prevalence in Navy recruits receiving single-dose benzathine penicillin prophylaxis was assessed during spring and fall 1989 by culturing throat specimens from randomly selected groups of approximately 230 men before and 2, 4, and 7 weeks after prophylaxis and from men with pharyngitis diagnosed at sick call. Of 60 GABHS isolates, 75% were serotype M-3. The pharyngitis rate increased from 0.18% in the spring to 1.55% in the fall with a concurrent increase in serotype M-3 prevalence from 35% to 91%. The GABHS prevalence rate was three- to fourfold lower after prophylaxis. There were no cases of acute rheumatic fever (ARF) despite predominance of M-3, a rheumatogenic serotype. It was concluded that penicillin prophylaxis continues to be effective for control of GABHS infections and prevention of ARF in Navy recruits.
