A Case of Ball Valve Thrombus.

Ball valve thrombus is a very rare cardiac pathological entity; most case reports are postmortem. It is always associated with a very tight rheumatic mitral stenosis. The antemortem diagnosis of ball valve thrombus has become easy with the advent of echocardiography and even easier with biplane or multiplane transesophageal echocardiography, including the three-dimensional acquisition of images. We present the case of a patient with a ball valve thrombus diagnosed during routine echocardiographic examination as a prelude to surgery.
