Abstract

This case report explores the left atrial mitral valve cord, an extremely rare congenital anomaly. Typically involving mitral valve leaflets and associated with mild mitral regurgitation, it is rarely documented independently. A 51-year-old patient presented with dizziness, and diagnostic challenges arose during transthoracic echocardiography (TTE). Advanced 3-dimensional transesophageal echocardiography (3D TEE) proved invaluable for accurate mapping, revealing a unique, unattached left atrial mitral valve cord.

摘要

本病例报告探讨了左心房二尖瓣索，这是一种极为罕见的先天性异常。它通常累及二尖瓣叶并伴有轻度二尖瓣反流，很少有独立的文献记载。一名51岁患者出现头晕症状，经胸超声心动图（TTE）检查时遇到了诊断难题。先进的三维经食管超声心动图（3D TEE）在精确成像方面证明具有极高价值，揭示了一条独特的、游离的左心房二尖瓣索。
