Two-dimensional and real time three-dimensional (RT-3D) TEE showed a massive, 75 mm length x 44 mm width, multilobulated, mobile mass occupying the entire right atrial and right ventricular cavities and extending into the coronary sinus, right ventricular outflow tract, and proximal inferior vena cava (Figures 1 and 2).
(A) 3-dimensional echocardiogram illustrating a giant myxoma extending into the inferior vena cave and the attachment site at the level of the eustachian valve. (B) 3-dimensional echocardiogram illustrating a giant myxoma occupying almost the entire cavity of the right atrium (RA) and right ventricle (RV).
