Meaning and Definition
One of the two valves in the human heart (specifically, the mitral valve) which regulates blood flow between the left atrium and left ventricle. It has two triangular flaps (cusps).
The anatomical structure, also known as the mitral valve, that prevents backflow of oxygenated blood from the left ventricle into the left atrium during ventricular contraction. Its dysfunction can lead to serious cardiac conditions.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or usage differences. Both use 'bicuspid valve' and 'mitral valve' interchangeably in medical contexts, though 'mitral valve' is more dominant in clinical practice. Spelling of related terms follows national conventions (e.g., 'valvular' vs. no difference).
Connotations
Equally technical in both regions. 'Bicuspid valve' might be slightly more common in introductory/educational texts as a descriptive term, while 'mitral valve' is universal in professional healthcare.
Frequency
'Mitral valve' is considerably more frequent than 'bicuspid valve' in professional medical literature, research, and clinical dialogue in both the UK and US.

FAQ
Frequently Asked Questions
Yes, they are two names for the same anatomical structure. 'Mitral valve' is the standard clinical term, while 'bicuspid valve' is a descriptive term referring to its two cusps.
It comes from the Latin 'bi-' meaning 'two' and 'cuspis' meaning 'point' or 'flap.' It describes the valve's structure of two leaf-like flaps.
Dysfunction can lead to mitral regurgitation (leakage, causing backflow of blood) or mitral stenosis (narrowing, restricting blood flow). Both conditions force the heart to work harder and can lead to heart failure if severe.
Yes, many people live with mild to moderate valve issues managed by medication and monitoring. Severe cases often require surgical repair or replacement of the valve to restore proper function and prevent heart damage.
