Prosthetic valve endocarditis due to Streptococcus pneumoniae

INTRODUCTION In the pre-antibiotic era up 10% of cases of infective endocarditis were due to Streptococcus pneumoniae, but this association is currently exceedingly rare. CASE DESCRIPTION Since 1997 we have diagnosed three patients, all aged >70, with endocarditis due to S. pneumoniae. One of these three cases involved a prosthetic valve, another a prosthetic ring. All three patients complete...

Late aortic silver graft re-infection due to Streptococcus milleri group (Streptococcus anginosus). Case report and literature review.

Mitral valve aneurysm due to severe aortic valve regurgitation.

A33-year-old man presented to the hospital with shortness of breath and chest pain. He was subsequently diagnosed with Streptococcus mitis endocarditis involving the aortic valve. The initial echocardiogram revealed moderate aortic valve regurgitation and a normal mitral valve without regurgitation. The patient was treated with afterload reduction and antibiotics.

Aortic Regurgitation due to Commissural Dehiscence of the Aortic Valve

Commissural dehiscence of the aortic valve is a rare cause of aortic regurgitation. We report a 53-year-old male who had progressive aortic regurgitation and aortic root dilatation. A flap or intimal tear of the proximal aorta was absent with echocardiography and computed tomography. Transesophageal echocardiography revealed prolapse of the right and left coronary cusps with no intimal flap in ...
