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. Three-dimensional imaging is a powerful diagnostic modality for diagnosing and characterizing lesions such as this as highlighted in this case image series where we describe how three-dimensional transesophageal echocardiography was utilized to characterize both complete and incomplete bridge type double orifice mitral valve.
