Parachute mitral valve

Parachute mitral valve (or PMV) is a rare congenital heart disease where the mitral valve only has a single papillary muscle from which all chordae tendineae originate. It is caused by an embryologic failure of papillary muscles to divide into two normally distinct columns, giving the mitral valve orifice and chordea an irregular, parachute-like appearance. Due to the abnormal anatomy, there are almost always associated mitral valve disorders, and because of its abnormal embryologic origin, PMV almost always coincides in a complex of other congenital heart defects.[1] PMV is usually identified during infancy or childhood due to its symptomatic nature, and hardly ever diagnosed during adulthood.
