Conclusion
Left atrial mitral valve chordae is a rare congenital abnormality which
has a broad range of clinical presentations. In our patient it mimicked
a vegetation on transthoracic echocardiography. Recognition of this
pathology is essential to avoid over diagnosis and treatment. In
patients with mild-moderate mitral regurgitation, close follow-up with
serial echocardiography is recommended given the risk of progression to
severe mitral regurgitation.
