Coagulase negative staphylococci are a rare cause of native valve endocarditis. Staphylococcus saprophyticus is a coagulase-negative Staphylococcus infrequently reported as a human pathogen, and most of the cases reported are urinary tract infections. We describe a case of native valve endocarditis attributed to this organism. The patient needed valve replacement due to heart failure.
The pseudoaneurysms of the ascending aorta are very infrequent but their diagnosis is important because of the associated high mortality. They usually appear in patients who have undergone aortic-related surgery, but the time that passes until they appear can be very prolonged and suspicious signs and symptoms can be quite anodyne. We present two cases of pseudoaneurysms of ascending aorta in two patients who underwent cardiovascular operations several months before, which were of such a considerable size that the first and practically the only symptoms were the sudden appearance of a pulsating thoracic mass because of pseudoaneurysm compression at this site.
