title: Migration of Kim-Ray Greenfield umbrella to the heart.
abstract: We have described a case of migration of a Kim-Ray Greenfield umbrella from the inferior vena cava to the heart for unknown reason. The umbrella was surgically removed and the patient recovered fully. This complication has not been previously reported. Despite this complication, we believe that the Kim-Ray Greenfield umbrella, when placed with particular attention to technique, effectively prevents pulmonary emboli and offers minimal associated morbidity.
