摘要：

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.
