title: [Leiomyosarcoma of the left side of the heart with a mitral symptomatology. Echocardiographic study].
abstract: A patient presented with the clinical findings of mitral stenosis, and angiocardiography revealed an intracardiac tumour. It was found at surgery to be a leiomyosarcoma, occupying almost the whole of the left auricle, and infiltrating the inter-atrial septum, the atrio-ventricular ring at the posterior commissure, and the posterior surface of the left ventricle. A mass with three lobes and a pedicle attaching it to the posterior wall and the ring of the mitral valve was found within the cavity of the left ventricle. The findings on echocardiography corresponded with the anatomical findings; but after surgery, ultrasonic investigation was found to be unreliable at detecting the unresected portion of the tumour, which was situated in the right postero-inferior region of the auricle of the left atrium.
