Anomalous Chord of the Left Atrium without Involvement of the Mitral Valve

Echocardiography, 03/16/2012

An anomalous chord from the left side of the atrial septum to the left atrial free wall was incidentally noted on transthoracic echocardiography in a 14–year–old boy with vasovagal syncope. Previously reported cases of anomalous chords in the left atrium were associated with the mitral valve leaflets in all but two cases. This is the first reported case of an echocardiographic diagnosis of anomalous left atrial chord without insertion of the chord into the mitral valve.
