Mitral Valve Prolapse
Mitral Valve Prolapse
Mitral Valve Prolapse (pronunciation: MY-trul VALV PRO-laps) is a condition in which the two valve flaps of the mitral valve don't close smoothly or evenly, but bulge (prolapse) upward into the left atrium.
Etymology
The term "Mitral Valve Prolapse" is derived from the Latin words "mitra" (meaning a type of headdress) and "valva" (meaning leaf of a folding door). "Prolapse" comes from the Latin "prolapsus" meaning "a slipping forth".
Definition
Mitral Valve Prolapse is a common heart valve disorder. When the heart beats, the flaps of the mitral valve bulge (prolapse) into the left atrium, sometimes allowing blood to leak back into the atrium. Most people with the condition are born with it, but its cause is unknown.
Symptoms
Most people with Mitral Valve Prolapse do not have symptoms, but when symptoms do occur, they may include palpitations, shortness of breath, fatigue, and chest pain.
