Key result
Multimodality imaging with TTE, TEE, and MDCT identifies rare anomalous mitral arcade in adult.
Why the study?
Anomalous mitral arcade is a rare congenital malformation with few patients surviving to adulthood, requiring detailed imaging for diagnosis.
Case Report (n=1)
No
Echocardiography and multidetector computed tomography are effective modalities for diagnosing the rare congenital malformation of anomalous mitral arcade in adults.
May support multimodality imaging for rare adult mitral arcade; leaves open prospective validation before routine adoption.
Anomalous mitral arcade is a rare congenital malformation and few survive to adulthood. A 65-year-old man presented with mild dyspnea and cardiac murmur. Transthoracic and transesophageal echocardiography showed an arc-like configuration of the papillary muscles, constrained by an interconnecting fibrous band in direct continuity with the anterior mitral leaflet, and mitral insufficiency caused by the restricted mobility of the mitral valve. Multidetector computed tomography confirmed these findings.

Kim et al. (2005) conducted a case report in Anomalous mitral arcade (n=1). Echocardiography and Multidetector Computed Tomography was evaluated on Diagnosis of anomalous mitral arcade. Transthoracic and transesophageal echocardiography, confirmed by multidetector computed tomography, successfully diagnosed a rare anomalous mitral arcade in a 65-year-old man.
