Abstract:
The presence of accessory left atrial chordae tendineae inserting into the mitral valve leaflet is extremely rare. Two long and thin accessory chordae tendineae, one arising from the left atrial dome and the other from the inferior interatrial septum, were incidentally identified during corrective surgery for severe mitral regurgitation from A3 prolapse. Triangular resection of the A3 portion of the anterior mitral valve leaflet including the double accessory chordae tendineae and primary repair followed by posterior ring annuloplasty was successfully performed.
