Three-dimensional imaging of left ventricular hemangioma

A 30-year-old asymptomatic man with chronic hepatitis B was evaluated for an incidentally visualized intracardiac mass on abdominal ultrasonography. Two-dimensional (2D) transthoracic echocardiography (TTE) revealed a structurally normal heart except for the presence of homogeneously echodense, round, mobile mass (2.0×2.8 cm) within the left ventricular cavity (Fig. 1a, Video 1a). No flow abnormalities were detected with Doppler analysis. On three-dimensional (3D) TTE, the mass appeared to be attached to the interventricular septum (Fig. 1b, Video 1b). Transesophageal echocardiography (TEE) was performed for superior visualization of anatomical details of the mass. On 2D TEE imaging with xPlane, the mass was well-demarcated and attached to the interventricular septum with a faintly visible stalk, and there was no infiltration of the myocardial wall (Fig. 2a, Video 2a). On real-time 3D TEE, the surface
