We describe the case of a 26-year-old man who developed severe aortic valve insufficiency due to a culturenegative endocarditis, leading to severe heart failure. The diagnosis of Bartonella quintana endocarditis was suspected from the clinical presentation and serological immunofluorescence assay, and was confirmed by polymerase chain reaction analysis of excised valve tissue after aortic valve...

Mitral valve leaflet aneurysm is a rare and potentially devastating complication of aortic valve endocarditis. We report the case of a 48-year-old man who had endocarditis of the native aortic valve and a concomitant aneurysm of the anterior mitral valve leaflet. Severe mitral regurgitation occurred after the aneurysm perforated. The patient showed no signs of heart failure and completed a 6-we...

Abstract Background Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is a rare complication infective endocarditis and aortic valve replacement. Ruptured P-MAIVF angina due to compression coronary arteries are severe complications this condition. Case presentation We report case that was diagnosed accidentally during routine checkup. The patient asymptomatic; however, she had...

Streptococcus bovis endocarditis has 18%-62% association with colonic neoplasms with multivalvular involvement and affects mainly elderly males leading to severe cardiac dysfunction, septic embolization, and neurological complications. The aortic valve is the commonest valve to be affected followed by aortic and mitral valves together. However, involvement of tricuspid valve is extremely rare. ...

Brucella abortus infection of the aortic valve caused acute aortic regurgitation leading to severe left ventricular failure in a 62-year-old man. He made an excellent recovery after emergency aortic valve replacement. This is the third reported case of successful heart valve replacement for Brucella endocarditis and the second such case involving the aortic valve.

The clinical and bacteriological findings in a case of prosthetic aortic valve endocarditis caused by Corynebacterium diphtheriae are presented. The patient died despite adequate medical therapy. This appears to be the first report of endocarditis caused by this species in a prosthetic aortic valve.

Aortic prosthetic valve endocarditis (PVE) is a potentially life-threatening disease. Mortality and incidence of infective endocarditis have been reduced in the past 30 years. Medical treatment of aortic PVE may be successful in patients who have a prompt response after antibiotic treatment and who do not have prosthetic dysfunction. In advanced stages, antibiotic therapy alone is insufficient ...

OBJECTIVE To assess the pattern and progression of aortic valve dysfunction by serial Doppler echocardiographic examinations in ambulatory adult patients with congenital bicuspid aortic valve. DESIGN AND SETTING Retrospective analysis of patients referred for Doppler echocardiography over a four year period. SUBJECTS Fifty one adult patients with echocardiographic diagnosis of congenital bi...

Multiple aorto-cardiac cavity communications is very rare but important complication of prosthetic aortic valve endocarditis. The case below illustrates multiple aorto-cardiac cavity fistula formation following prostethic aortic valve endocarditis presented with slowly progressive symptoms of heart failure. A brief review of surgical reconstruction and the existing literature are presented, inc...

Although Staphylococcus capitis is considered to be a rare causative organism for prosthetic valve endocarditis, we report 4 such cases that were encountered at our hospital over the past 2 years. Case 1 was a 79-year-old woman who underwent aortic valve replacement with a bioprosthetic valve and presented with fever 24 days later. Transesophageal echocardiography revealed an annular abscess in...
