Mitral Annular Calcification

Mitral Annular Calcification (MAC) is a chronic, degenerative calcification of the mitral valve annulus in the heart. It is often associated with aging and is more common in women than in men.

Pronunciation

Mitral: /ˈmaɪtrəl/ Annular: /ˈæn.jʊ.lər/ Calcification: /ˌkæl.sɪ.fɪˈkeɪ.ʃən/

Etymology

The term "Mitral" is derived from the Latin word "mitra", meaning a bishop's mitre, due to the resemblance of the mitral valve to a bishop's hat. "Annular" comes from the Latin "annulus" meaning ring, referring to the ring-like structure of the valve. "Calcification" is derived from the Latin "calx" or "calcis" meaning lime or limestone and the suffix "-fication" meaning the act or process of making.

Definition

Mitral Annular Calcification is a condition characterized by the deposition of calcium (a hard, white mineral) in the mitral valve annulus, a ring-like structure in the heart that helps control blood flow. This can lead to stiffening or hardening of the valve, which can affect its function.

Symptoms

Symptoms of Mitral Annular Calcification may include shortness of breath, fatigue, palpitations, and chest pain. However, many people with MAC may not experience any symptoms.

Causes

The exact cause of Mitral Annular Calcification is unknown, but it is often associated with aging and is more common in people with certain conditions such as hypertension, kidney disease, and diabetes.

Treatment

Treatment for Mitral Annular Calcification may include medications to manage symptoms and underlying conditions, and in severe cases, surgery may be required to repair or replace the mitral valve.
