(HealthDay)—Individuals with bicuspid aortic valve (BAV) and mitral valve prolapse (MVP) have a higher risk of developing infective endocarditis (IE) than the general population, according to a study published in the June 19 issue of theJournal of the American College of Cardiology. Isabel Ze...
Valve diseaseAntimicrobial therapyProphylaxisInfective endocarditis (IE) results when microbial agents infect the endothelial surface of the heart. Heart valves are the most common site for this process; however, occasionally infection develops on the low-pressure side of a ventricular septal defect, on...
Alpha-hemolytic streptococci or enterococci, usually in the setting of underlying structural valve disease, typically are the causative agents of this type of endocarditis. PVE accounts for 10-20% of cases of IE. Eventually, 5% of mechanical and bioprosthetic valves become infected. Mechanical valves...
Indeed, a mortality of 40% or more among patients with prosthetic-valve infective endocarditis due to Staphylococcus aureus has been reported [3]. The mortality from IE due to VGS involving native valves is much lower and is estimated at 5% compared to up to 20% when prosthetic valves are ...
microbes) enter the blood stream and attack the lining of the heart or the heart valves. Bacterial endocarditis causes growths or holes on the valves or scarring of the valve tissue, most often resulting in a leaky heart valve. Without treatment, bacterial endocarditis can be a fatal disease...
Pulmonary valve (PV) infective endocarditis (IE) is a rare entity, accounting for 1.5% to 2% of cases of IE. Published data are limited to a few case series and reports. We sought to review the Mayo Clinic experience and describe clinical, echocardiographic, and microbiologic features. We in...
For the others, prostheses were used (mechanical for aortic valve and bioprostetic for mitral valve in the majority of the cases). Reoperation was frequent. Ventricular septal defect was the most common congenital pathology (3 cases) and 4 patients presented infective endocarditis in pacemaker wire...
INFECTIVEPRIMEVIEW ENDOCARDITIS Infective endocarditis (IE) results from infection — usually bacterial — of the endocardial surface of the heart and most commonly affects the heart valves. As a multisystem disease, IE can have cardiac, pulmonary, renal and neurovascular manifestations, among others....
When prosthetic valves were infected endocarditis of early onset was staphylococcal but that of late onset was streptococcal. Narcotic abuse was a common cause of staphylococcal endocarditis, second only to surgical wound infection following valve replacement. Streptococci affected the mitral and aortic ...
The disease is reported to be twice as common in men as in women. Today, the average age of patients with infective endocarditis is over 65 years, which is probably due to the increasing prevalence of predisposing factors such as artificial valves, acquired valve disease, diabetes mellitus and...
