1/1142. aortitis with multiple aneurysms mimicking infective endocarditis.aortitis usually produces aortic insufficiency by aortic root dilation. In rare cases the inflammation may involve the aortic valve cusps, causing valvular insufficiency. A patient in whom aortitis produced valvular masses, with aortic and peripheral arterial aneurysms, embolic episodes and aortic insufficiency is described. Valve replacement for suspected infective endocarditis was complicated by homograft dehiscence and multiple false aneurysms. Although immunosuppression was successful in decreasing the patient's vasculitis, he became infected and died of complications of aspergillus infection.- - - - - - - - - - ranking = 1keywords = valve (Clic here for more details about this article) |
2/1142. A case of Austrian's syndrome with ocular involvement.A man with a history of alcohol abuse was admitted to hospital with pneumonia and meningitis due to streptococcus pneumoniae. Because of the worsening of respiratory function and the persistence of fever, an echocardiographic examination was made, which showed endocarditis with destruction of the aortic valve. The patient underwent surgical valve replacement. In addition, he showed a choroiditis in the left eye which improved after antibiotic therapy. The interest of this case lies in the rarity of the triad described as Austrian's syndrome and in the coexistent fourth septic localization, namely in the left eye.- - - - - - - - - - ranking = 2keywords = valve (Clic here for more details about this article) |

4/1142. Mycotic aneurysm complicating staphylococcal endocarditis.OBJECTIVE: To emphasize the role of noninvasive diagnostic investigative methods and their importance in early detection of mycotic aneurysm related to staphylococcal endocarditis, and of monitoring therapy or identifying complications. patients AND methods: Two patients with mycotic aneurysm that developed as complications of staphylococcal endocarditis are presented. The first patient had mesenteric artery mycotic aneurysm and presented with sudden rupture one month after initial diagnosis of mitral valve infective endocarditis and completion of a full course of antimicrobial therapy. The second patient had multiple cerebral mycotic microaneurysms and presented with hemorrhagic cerebral embolization from aortic valve infective endocarditis. RESULTS: The first patient died because of ischemic cerebral edema 48 h after rupture of the mesenteric artery mycotic aneurysm and massive hemoperitoneum, which was treated surgically with distal ileal resection and ileostomy. The second patient was alive two years after prolonged antimicrobial therapy and aortic replacement to treat moderate aortic regurgitation and progressive left ventricular enlargement. CONCLUSIONS: Mycotic aneurysm is a rare complication of infective endocarditis but has a high mortality rate because of its early or late potential catastrophic rupture. diagnosis by noninvasive diagnostic imaging techniques of mycotic aneurysm before rupture would be beneficial for its treatment.- - - - - - - - - - ranking = 2keywords = valve (Clic here for more details about this article) |
5/1142. mitral valve homograft for mitral valve replacement in acute bacterial endocarditis.Homograft use for aortic valve replacement (AVR) in aortic valve acute bacterial endocarditis (ABE) has gained in popularity, due mainly to the relative resistance of homografts to infection. Recent success with mitral valve homograft use led us to apply homograft mitral valve replacement (MVR) in a patient with severe ABE that was not amenable to valve repair. Following surgery, the patient improved rapidly with normalization of infection parameters and chest radiography, and was discharged home on postoperative day 11. Follow up echocardiography showed good function of the homograft mitral valve with no regurgitation. After four months, the patient had normal valve function, with no evidence of infection. In conclusion, MVR with a mitral valve homograft in the setting of ABE was satisfactory, though patient follow up was relatively short (four months).- - - - - - - - - - ranking = 16keywords = valve (Clic here for more details about this article) |
6/1142. Visualization of mitral valve aneurysm by transesophageal echocardiography.This article describes the transesophageal echocardiographic findings in a patient with pathologically proven mitral valve aneurysm. This aneurysm probably occurred as a complication of aortic valve endocarditis. Transesophageal echocardiography showed a saccular structure attached to the left atrial side of the anterior mitral leaflet with systolic expansion and diastolic collapse, and its orifice was visualized with excellent resolution. Transesophageal echocardiography is a useful diagnostic tool for evaluation of mitral valve aneurysm.- - - - - - - - - - ranking = 7keywords = valve (Clic here for more details about this article) |
7/1142. The Freestyle stentless bioprosthesis for prosthetic valve endocarditis.We report a case of methicillin-resistant staphylococcus aureus-induced prosthetic valve endocarditis, which was successfully treated with aortic valve replacement using the Freestyle stentless bioprosthesis. The total root and stentless design of this bioprosthesis allows for more radical removal of infected tissue and easier treatment for annular abscess, while requiring less prosthetic materials than a conventional prosthesis. This bioprosthesis thus seems to be a valuable option for active endocarditis.- - - - - - - - - - ranking = 6keywords = valve (Clic here for more details about this article) |
8/1142. bacillus popilliae endocarditis with prolonged complete heart block.bacillus popilliae, a fastidious, aerobic, gram-positive, spore-forming bacillus, has never been reported as a pathogen in human infectious diseases. We report the first case of a human infected by the pathogen B. popilliae, which presented as endocarditis involving the bicuspid aortic valve and complicated with prolonged (> 30 days; to our knowledge, the longest in the literature) complete heart block. Although surgery may be warranted by previous reports, the patient was successfully managed by medical treatment instead, because of the absence of evidence from various approaches that support the existence of perivalvular extension of infection.- - - - - - - - - - ranking = 1keywords = valve (Clic here for more details about this article) |
9/1142. culture-positive bartonella quintana endocarditis.A 50-year-old alcoholic man with a 1-year history of pyrexia of unknown origin was admitted with symptoms of endocarditis. Large vegetations on his mitral and aortic valve were found on echocardiography. Using the Bactec 9240 system. bartonella quintana could be grown from two culture sets of blood collected before the start of antimicrobial therapy. This is the first case report of culture-proven bartonella infection in the UK. and is noteworthy because bartonella quintana was detected in conventional blood culture systems after prolonged incubation.- - - - - - - - - - ranking = 1keywords = valve (Clic here for more details about this article) |
10/1142. Recurrent endocarditis in silver-coated heart valve prosthesis.BACKGROUND AND AIM OF THE STUDY: In order to prevent prosthetic valve endocarditis (PVE), the implantation of a new silver-coated sewing ring has been introduced to provide peri- and postoperative protection against microbial infection. methods: A 56-year-old woman with aortic stenosis had elective replacement with a St. Jude Medical mechanical valve fitted with a silver-coated sewing ring (Silzone). The patient developed early PVE, which necessitated reoperation after one month. Despite a second Silzone prosthesis being implanted, the endocarditis recurred. During a third operation an aortic homograft was implanted, and after six months a fourth operation was performed for a pseudoaneurysm at the base of the homograft, in proximity to the anterior mitral valve leaflet. RESULTS: The diagnosis of PVE was confirmed by the presence of continuous fever, transesophageal echocardiography and growth of penicillin-resistant staphylococcus epidermidis from the valve prosthesis. CONCLUSION: The implantation of all prosthetic valves is encumbered with a risk of endocarditis. Although silver has bacteriostatic actions, the advantages of silver-coated prostheses in the treatment of this condition have yet to be assessed in clinical trials.- - - - - - - - - - ranking = 9keywords = valve (Clic here for more details about this article) |
