P174 Left atrial myxoma presenting in a cystic form

Abstract

Abstract Background Early diagnosis of atrial myxomas may be a challenge because of their synptoms are often nonspecific. Two-dimensional echocardiography is the diagnostic procedure of choice. Case presentation A 42-year-old woman presented with complaints of palpitation and fatigue. Physical examination revealed a diastolic murmur at the apex. Two-dimensional transthoracic echocardiography revealed an extremely mobile mass in the left atrium that consisted of multiple cystic and solid parts. Three-dimensional transesophageal echocardiography showed that the 4.3x3.3 cm mass was connected to the interatrial septum through a 0.7 cm pedincle, and it moved between the atrium and the ventricle through the mitral valve with each carciac cycle. Grade 1 mitral and aortic regurgitation and grade 3 tricuspid regurgitation was accompanied by a SPAP of 90 mmHG. The mass was surgically excised. Histopathologic diagnosis was myxoma. Discussion Types of cystic masses that can appear in the left atrium are myxomas, hydatid cysts and interatrial septal aneurysms. In our case report, echocardiographic findings of a mass that was connected to the IAS with a pedicle were supportive of cardiac myxoma. If not removed, myxomas may cause major complications like stroke, rupture, and hemodynamic problems. Surgery was indicated because the mass was cystic and highly mobile. Abstract P174 Figure. mass
