Myxomatus Mitral Valve Prolapse

Back

Myxomatus mitral valve prolapse also called as mitral valve prolapse (mvp) occurs when the leaflets of the mitral valve bulge (prolapse) into the heart's left upper chamber (left atrium) like a parachute during the heart's contraction.

SYMPTOMS

A racing or irregular heartbeat (arrhythmia)
Dizziness or lightheadedness
Difficulty breathing or shortness of breath, often when lying flat or during physical activity
Fatigue
Chest pain that's not caused by a heart attack or coronary artery disease

CAUSES

When your heart is working properly, the mitral valve closes completely during contraction of the left ventricle and prevents blood from flowing back into your heart's upper left chamber (left atrium).
But in some people with mitral valve prolapse, one or both of the mitral valve's flaps (leaflets) have extra tissue bulging (prolapsing) like a parachute into the left atrium each time the heart contracts.
