Mini‐Abstract Aberrant left atrial mitral valve chords are rare causes of mitral regurgitation (MR). An aberrant chord to the posterior mitral valve leaflet has not been reported. Transesophageal echocardiogram demonstrated a chord‐like structure from the left atrium to the middle (P2) scallop of the posterior mitral leaflet, causing focal P2 prolapse without typical myxomatous degeneration. Three‐dimensional images revealed that the chord terminated on a papillary muscle‐like structure within the left atrium. There was mild MR. Focal mitral leaflet prolapse without typical myxomatous change may herald the presence of an aberrant chord.
