A transesophageal echocardiogram confirmed the presence of a pedunculated right atrial mobile bilobular mass measuring 2.1 x 1.8 cm, not arising from the interatrial septum with extension into the inferior vena cava (Figures 1-3).
TEE showing the mass is not attached to the interatrial septum (IAS).
