Intracardiac thrombus-in-transit characterized on 3-dimensional transesophageal echocardiography.

A 60-year-old woman presented with fever and shortness of breath of one week's duration. Physical examination disclosed a right-lower-quadrant abdominal mass and pretibial edema. A chest computed tomogram showed bilateral pulmonary embolism, and venous Doppler ultrasonographic imaging of the lower extremities revealed acute deep vein thrombosis (DVT) of the right common femoral vein. Abdominal ultrasonograms showed a large right ovarian mass. A 2-dimensional transthoracic echocardiogram (2D TTE) showed an echogenic mass in the atria. Two-dimensional transesophageal echocardiograms (TEE) revealed an aneurysmal interatrial septum and a large, mobile mass in the right atrium. The mass was in transit through a patent foramen ovale and extended into the left atrium (Fig. 1). Three-dimensional (3D) TEE helped to characterize the mass as a thrombus-intransit that extended through the interatrial septum (Fig. 2). Upon sequential cropping of the images, echolucent components seen inside the mass were consistent with an intracardiac thrombus.1 The ovarian mass was found to be malignant. The patient was prescribed long-term anticoagulation. After 6 months, 2D TTE revealed complete resolution of the thrombus and no evidence of left-sided emboli.
