Left atrial myxoma in parasternal long axis view
Left atrial myxoma is a primary cardiac tumour, which is much less common than the secondary cardiac tumours. Echocardiogram demonstrates left atrial myxoma very well.
Left atrial myxoma in parasternal long axis view - annotated
Annotated view of echocardiogram in parasternal long axis view showing left atrial myxoma.
Left atrial myxoma prolapsing into LV in diastole
Left atrial myxoma seen on echocardiogram in parasternal long axis view as a mass prolapsing into the left ventricle in diastole. The site of attachment of the myxoma is not evident in this view. A four chamber view had shown that it is actually attached to the inter atrial septum. Myxoma is the commonest primary cardiac tumour in the adult, and it is usually seen in the left atrium. Right atrial myxomas are rare. Sometimes myxomas can be familial.
Left atrial myxoma with mitral regurgitation jet
Mosaic mitral regurgitation jet is seen in the left atrium skirting the myxoma anteriorly and left atrial wall posteriorly.
Video showing left atrial myxoma prolapsing into the left ventricle and colour Doppler imaging demonstrating mitral regurgitation. The left ventricle is dilated and the contractions are poor possibly due to associated dilated cardiomyopathy, either ischemic or idiopathic.
