Accessory left atrial cords: A case report and literature review.

ABSTRACT

INTRODUCTION: Accessory left atrial cords are fibroelastic structures found in the left atrium. Left atrial cords may be associated with mitral valve disease, atrial fibrillation, stroke, and other congenital left-side anomalies. METHODS: We presented the case of a man with severe Mitral Regurgitation and two accessories left atrial cords attached to P2 scallop by a single tendon and performed a literature review using PUBMED/MEDLINE, Web of Science, and EMBASE databases on December 4, 2021. RESULTS: According to our review, accessory left atrial cords were found more frequently in women (36 patients, 62%), more frequently attached to the mitral valve (66% of reports) and mitral regurgitation was the most frequently reported pattern of mitral valve disease (64.2%). No other cases of double left atrial cords attached to P2 segment were found. CONCLUSION: Accessory left atrial chords may be related to mitral valve disease and other left-side congenital abnormalities. These structures were found more frequently in females and A2 insertion was the most frequently observed pattern in the review.
