Atrial Myxoma

  • This is the most common primary cardiac tumour.
  • It occurs at all ages and shows no sex preference.
  • mostmyxomas are sporadic
  • Histologically they are benign.
  • The majority of myxomasare solitary, usually develop in the left atrium
  • The tumour may obstruct the mitral valve or may be a site of thrombi that then embolize.
  • It is also associated with constitutional symptoms: the patient may present with dyspnoea, syncope or a mild fever.
  • The physical signs are a loud first heart sound, a tumour ‘plop’ (a loud third heart sound produced as the peduncu- latedtumourcomes to an abrupt halt), a mid-diastolic murmur and signs due to embolization.
  • A raised ESR is usually present.
  • The diagnosis is easily made by echocardiography because the tumour is demonstrated as a dense space- occupying lesion
  • Surgical removal usually results in a complete cure.

Cut away view of a massive left atrial myxoma arising from the atrial septum and flopping in and out of the Left ventricular inflow path. This case presented with symptoms of mitral stenosis. Image reconstructed on a TeraRecon Workstation with blood digitally edited from the cavity of the left atrium and ventricle, This reveals the complex 3D shape of the tumor, prone to embolize if not surgically resected.

Tumour of the Heart (Left Atrial Myxoma)
Myxoma is a Rare Benign Tumour of the Heart. it usually originates from the Left Atrial septum. as it enlarges in size it interferes with the normal function of the Mitral Valve, obstrcting the Flow of blood into the left Ventricle and giving symptoms of Mitral Stenosis (narrowing). The Tumour can be friable and fragments may Embolize to the Brain and present as a Sroke or Sudden Death.
Left Atrial Myxoma- Commonest Tumor of the Heart.
This video demonstrates the removal of a left atrial myxoma. Bicameral approach was used and the defect in the interatrial septum was patched with autologous pericardium.

Left Atrial Myxoma – Carney Complex
Left Atrial Myxoma as seen on echocardiography, this is a 47 years old male who presented with symptoms sugestive of systemic embolization to our clinic and on physical examination we found distinct diastolic rumble. Tumor flop was absent. Echo showed atrial myxoma
