Abstract:
Multiple myxomas in the ventricles, causing pulmonary obstruction, are extremely uncommon. We treated multiple myxomas, seemingly clinically malignant, which had caused acute right heart failure due to their position in the outlet of the right ventricle. The position of the myxomas obstructed the pulmonary artery. To prevent the right heart from failing, we proceeded with tumor resection with the cardiopulmonary bypass on a beating heart and added cryoablation. Following the removal of the tumor, symptoms improved drastically. The postoperative course was uneventful.
