[Early diastolic sound in a patient with hepatocarcinoma].

On physical examination an early diastolic sound is usually associated with mitral stenosis, prosthetic mitral valve replacement and chronic constrictive pericarditis. In case of an atrial myxoma, an early diastolic sound can be usually heard due to movement of the tumor towards the tricuspid valve (tumor plop). The following case report shows an example in which an early diastolic sound was heard in a patient presenting with a hepatocellular carcinoma. This sound was due to the presence of a thrombus that originated from the inferior vena cava and invaded the right atrium up to the tricuspid valve. It was thus similar to an atrial myxoma and produced a tumor plop.
