title: [Doppler echocardiography in atrial myxoma].
abstract: Two-dimensional echocardiography is the technique of choice for the diagnosis of atrial myxoma. In fact the Echo study allows the recognition of the presence of the tumor, and can show its dimensions, shape, implantation site and motility. However, it is not clear the role of Doppler echocardiography in the evaluation of atrial myxoma. This technique could be useful to recognize patients with more severe obstruction to atrioventricular flow due to large tumors. In 4 patients with large atrial myxomas (3 left and 1 right atrial myxoma) Doppler analysis of atrioventricular flow showed an apparent correlation between variation of trans-mitral or trans-tricuspid diastolic flow and symptoms (syncopal attacks). Only patients with an obstruction to atrioventricular flow and severely restricted calculated mitral or tricuspid orifice had syncopal attacks, at variance with patients without flow obstruction. Further studies on larger population will verify this apparent relation between atrioventricular flow obstruction and clinical symptoms in patients with large atrial myxoma.
