title: Left ventricular myxoma originating from the papillary muscle.
abstract: A rare case of left ventricular myxoma presenting embolization into the brachial artery is reported. The sessile tumor originated from the posteromedial papillary muscle and involved the chorda supporting the posterior mitral leaflet. Complete excision of the tumor with the posterior head of the posteromedial papillary muscle, with the chorda and with the posterior mitral leaflet necessitated valve replacement. The tumor was well visualized by the superior-septal and transaortic approaches. These enabled exploration of all four cardiac chambers so as not to overlook any multifocal myxoma. The left ventricular myxoma should be completely resected with the surrounding endocardium in order to avoid recurrence of the disease.
