Meaning and Definition
A condition where the mitral valve in the heart fails to close properly, allowing blood to leak backward (regurgitate) into the left atrium when the left ventricle contracts.
Also called mitral regurgitation. This cardiac valve disorder increases the workload on the heart, potentially leading to heart failure, arrhythmias, or pulmonary hypertension if left untreated. It can be acute or chronic, degenerative, ischemic, or functional in etiology.
Dialectal Variation
British vs American Usage
Differences

FAQ
Frequently Asked Questions
No. A heart attack (myocardial infarction) is damage to the heart muscle from blocked blood flow. Mitral insufficiency is a valve problem. However, a heart attack can *cause* mitral insufficiency by damaging the structures that support the valve.
Stenosis means the valve is narrowed and doesn't open properly, obstructing blood flow forward. Insufficiency (or regurgitation) means the valve doesn't close properly, allowing blood to leak backward.
It can often be effectively treated. Mild cases may just require monitoring. For significant cases, treatment includes medication to manage symptoms and reduce strain on the heart, or surgical procedures to repair or replace the faulty valve.
Chronic cases may have no symptoms for years. When they appear, common symptoms include shortness of breath (especially when active or lying down), fatigue, palpitations (feeling of rapid heartbeat), and swollen feet or ankles.

Learning
Memory Aids
Mnemonic
Think of the mitral valve as a one-way door. INSUFFICIENCY means it's not sufficient/strong enough to stay shut, so blood sloshes back through.
Conceptual Metaphor
A FAULTY FLAPPER VALVE: Conceptualizing the heart valve as a mechanical valve that is worn, torn, or stuck open, failing to seal the chamber properly.
