TTE showed shaggy biatrial large masses, the right atrium mass is extending from the roof along the interatrial septum (IAS) and protruding to the right ventricle through tricuspid valve (2.9 * 3.7 cm), the left atrium mass (1.4 * 2.3 cm) was attached to the IAS inferiorly (Fig. 1).
Transesophageal echocardiography showing A) large heterogenous mass in the right-side prolapsing through tricuspid valve. B) bi-atrial masses sharing the same attachment at the distal part of fossa ovalis.

A computerized tomography (CT) of the chest, abdomen, and pelvis showed the same findings (Fig. 3) as well as bilateral breast nodular masses, hepatomegaly with two small cysts and right renal cortical cysts without renal stones or hydronephrosis.
A) Macroscopic appearance of two myxomas: right myxoma (right), left myxoma with part of IAS and some of the right mass (left). B) intraoperative repair of the IAS with an autologous pericardium.
