Abstract:
A 52-year-old woman with a past history of anterior myocardial infarction 15 years previously was found to have a pedunculated mobile thrombus with a narrow stalk originating from the left ventricle, and a huge laminated mural thrombus. Surgical extraction of the two organized thrombi was successfully performed with transmitral approach using a novel, flexible, self-retained, and reusable leaflet retractor, which was originally developed for exposure of the subvalvular apparatus during mitral valve repair. Excellent access, exposure, and visualization of the left ventricle were achieved by this heart valve retractor and an endoscope for removal of a huge mural thrombus.
