A late presentation of congenital cardiac anomaly: Accessory chordae from the left atrium causing severe mitral regurgitation.

Mitral regurgitation secondary to accessory mitral valve (MV) chordae of the left atrium is an extremely rare congenital disease. A 85-year-old female (NYHA I-II) was hospitalized for investigations. An echocardiogram showed calcification of the MV with mild stenosis and moderate regurgitation.
