Background. Lactococcus, a gram-positive organism of low virulence, is an uncommon cause of human infection. Infective endocarditis due to Lactococcus is extremely rare. Methods. We present a case of native aortic valve endocarditis due to Lactococcus garvieae with severe aortic insufficiency requiring valve replacement. Results. The patient is a sixty year old male with history of Waldenstrom’...

The bicuspid aortic valve is a common congenital cardiac anomaly, having an incidence in the general population of 0.9% to 2.0% and a frequency of 54% in all patients aged >15 years with valvular aortic stenosis. In most cases it remains undetected until infective endocarditis or calcification supervenes. The bicuspid aortic valve may function normally throughout life, may develop progressive c...

Coagulase negative staphylococci are the principal cause of prosthetic valve endocarditis but are a rare cause of native valve infections. However, the incidence of native valve endocarditis is increasing. Staphylococcus capitis is a coagulase negative staphylococcus with the capacity to cause endocarditis on native heart valves. Two cases of native valve endocarditis caused by S capitis are pr...

Transcatheter aortic valve implantation (TAVI) constitutes an established treatment in inoperable or high perioperative risk patients with severe aortic stenosis, demonstrating similar mortality rates (at 30 days and 1 year) with surgical aortic valve replacement (SAVR). Various complications have been reported during TAVI, weeks or months post procedure. The most frequent causes of transcathet...

Staphylococcus epidermidis (SE) is the leading pathogen of prosthetic valve endocarditis. At the same time it is a very rare cause of native valve endocarditis and it follows a clinical course and outcome similar to Streptococcal viridans endocarditis. We report here the case of a 41-year-old man with a community acquired SE endocarditis of a native aortic valve. Despite early surgical interven...

Coagulase negative staphylococci are the principal cause of prosthetic valve endocarditis but are a rare cause of native valve infections. However, the incidence of native valve endocarditis is increasing. Staphylococcus capitis is a coagulase negative staphylococcus with the capacity to cause endocarditis on native heart valves. Two cases of native valve endocarditis caused by S capitis are pr...

UNLABELLED Infective endocarditis in hypertrophic obstructive cardiomyopathy is rare. Management of this disease is challenging due to the unique features of dynamic pressure gradient over the left ventricular outflow tract and its unpredictable interaction with the management of sepsis. The added complexity of infective endocarditis further complicates an already difficult situation. A 72-year...

Monro, J. L., Gavin, J. B., and Barratt-Boyes, B. G. (1974). Thorax, 29, 323-328. A comparison of antibiotic-sterilized, stent-mounted pulmonary and aortic valve allografts in the mitral region of dogs. The mitral valves of 40 dogs were replaced with antibioticsterilized, stent-mounted semilunar valve allografts. Twenty grafts were pulmonary valves and 20 were aortic valves. Six dogs in each gr...

Background Aorto-right-atrial fistula in native valve endocarditis is very rare. Case Description A 45-year-old woman was referred with an endocarditis with a perforated right cusp of the aortic valve with at least moderate insufficiency and an affected tricuspid annulus with vegetations. In addition to this, an aorto-cavitary fistula from the aortic sinus to the right atrium with a holodiastol...

Aneurysm of the mitral valve, although uncommon, occurs most commonly in association with infective endocarditis of the aortic valve and true mitral valve aneurysm is a rare cause of mitral regurgitation. We report a case with perforated mitral valve aneurysm in the posterior leaflet without concurrent infective endocarditis initially mistaken diagnosis of cystic mass, which was confirmed at op...
