Print Intracardiac complications and heart failure were common in patients considered high risk and patients with either bicuspid aortic valve or mitral valve prolapse.
Infective endocarditis in patients with concurrent bicuspid aortic valve or mitral valve prolapse was associated with higher rates of viridans group streptococci and had a clinical course similar to that of high-risk patients, according to a recent study published in the Journal of the American College of Cardiology.
Continue Reading Below Of the patients enrolled in the study, 54 had bicuspid aortic valve and 89 had mitral valve prolapse. In patients with mitral valve prolapse or bicuspid aortic valve, the most common cause of infective endocarditis was organisms originating in the oral cavity, mainly viridans group streptococci.
Intracardiac complications and heart failure were common in both groups. The study authors wrote, "[T]he analysis of the clinical characteristics in [bicuspid aortic valve] and [mitral valve prolapse] patients with [infective endocarditis] revealed an aggressive clinical course with a similar proportion of [infective endocarditis] complications to that of [infective endocarditis] patients with high-risk cardiac conditions, and more intracardiac complications than in patients of the low-risk and intermediate-risk groups.However, today we recognize and have treatment for the most potentially devastating aspects of this disease: bicuspid aortic valve failure, possible failure of the mitral or other heart valves, aortic aneurysm, aortic dissection, and brain aneurysm.

cusps. Mitral Valve aka Bicuspid Valve Human Anatomy & Physiology II The left atrioventricular valve, with two cusps, is called the mitral valve because it resembles the two-sided bishops miter or hat.
It is sometimes called the biscuspid valve. (Marieb & Hoehn, ). This valve separates the left atrium of the heart from the left ventricle of the heart. Q: What is the mitral valve? A: The mitral valve (also known as the bicuspid valve or left atrioventricular valve) is a dual-flap valve in the heart that lies between the left atrium (LA) and the left ventricle (LV).
Q: How does the mitral valve function? A: A normally functioning mitral valve opens as a result of increased pressure from the left atrium as .

The average size of an aortic valve is cm². The three leaflets or flaps of the valve – the right cusp, the left cusp, and the posterior cusp (aka the non-coronary cusp) – attach to both the wall of the aorta (the body’s main artery) and a .
