Successful one-stage extraction of an intracardiac and intravenous leiomyoma through the right atrium under transesophageal ultrasound monitoring
2014
Purpose
Intravenous leiomyomatosis is a rare disorder characterized by benign smooth-muscle tumours, termed leiomyomas, which originate from uterine leiomyomas or pelvic veins. Tumours may extend into the right-sided heart chambers, termed intracardiac leiomyomatosis (ICLM), and may be potentially life-threatening due to mechanical interference with cardiac structures or pulmonary arteries. While surgical excision is the optimal therapy, incomplete retrieval of a tumour or fatal retroperitoneal hemorrhage may occur. We present a case where intraoperative transesophageal ultrasound (TEU) guided complete removal of an intracardiac leiomyoma in a single-stage surgery solely through the right atrium without vein injury.
