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.
