Double-Orifice Mitral Valve: Diagnosis and Characterization with Three-Dimensional Transesophageal Echocardiography

Double orifice mitral valve is a rare congenital anomaly that is often associated with other congenital cardiac abnormalities. Patients may present with valvular dysfunction or may be asymptomatic and have an incidental diagnosis of double outlet mitral valve. Whether symptoms due to this pathology are present or not, it is important to accurately characterize this lesion. 3-dimensional imaging is a powerful diagnostic modality for diagnosing and characterizing lesions such as this as highlighted in this case image series.
