title: Involvement of the right atrium by malignant lymphoma as a cause of right cardiac failure: report of a case.
abstract: We describe herein a rare case of malignant lymphoma occupying almost the entire space of the right atrial cavity and causing low cardiac output syndrome. A life-saving emergency operation was carried out after the establishment of a temporary bypass between the axillary and femoral veins to prevent exacerbation of the patient's condition during the induction of anesthesia. Cardiopulmonary bypass was commenced and the right atrium was opened. A large tumor in the right atrium could not be completely removed due to invasion of the atrial wall. A bypass from the left innominate vein to the pulmonary arterial trunk was constructed with a prosthetic graft to convert the blood flow directly from the systemic vein to the pulmonary artery. Postoperative radiation treatment was given, which resulted in reducing the size of the tumor considerably, and the patient is doing well 1 year after his operation.
