	Introduction

Top Introduction

 
A 48-year-old woman with a history of syncope was referred from another hospital to our institution with a diagnosis of suspected left atrial myxoma. Multiplane transesophageal echocardiography with a rotational approach and subsequent three-dimensional reconstruction with dynamic display was performed. A mass in the left atrium was visualized (A). Different cut planes allowed the demonstration of the site of insertion of the tumor stalk to the interatrial septum (B). At surgery, the diagnosis of a left atrial myxoma was made and the site of its attachment to the interatrial septum confirmed (C).

The left atrial cavity (LA) is almost completely filled by a tumor mass (T). In this section, part of the interatrial septum (IAS) and interventricular septum (IVS) is shown, but the point of insertion of the tumor cannot be assessed. MA indicates mitral annulus; LV, left ventricle; RA, right atrium; RV, right ventricle; and TV, tricuspid valve. B, With a section through a different plane, the stalk of the tumor was visualized (arrow). The continuity between the tumor mass and the interatrial septum is clearly shown. C, Finding at surgery. The attachment of the tumor to the interatrial septum (see box) resembles the image shown in B. Bar=1 cm.
