Introduction

|---|
A 56-year-old man presented with
dyspnea and chest discomfort
following gastrectomy for metastatic
adenocarcinoma. Transthoracic
echocardiography showed a
mass in the right atrium (RA); he
subsequently underwent
transesophageal echocardiography
using
a biplane probe. Imaging done in the horizontal plane (Fig 1

)
showed a mass (arrows) in the RA; vertical plane
imaging (Fig
2

) revealed a serpentine mass (arrows)
originating in the superior
vena cava (SVC) and extending into the RA,
consistent with thrombus.
AO indicates aorta; IVC,
inferior vena cava; and LA, left atrium.
