A 25-year-old man with a history of bone-marrow-transplantation for the treatment of Löffler's endocarditis underwent surgery for massive tricuspid regurgitation with paroxysmal atrial flutter. Dense fibrosis in the right ventricular endocardium with complete obliteration of the apex was seen intraoperatively, and the right ventricular cavity was diminished. Annular dilatation of the tricuspid valve and entrapment of the posterior leaflet to the endocardial fibrosis were also seen. Annuloplication at the posterior leaflet was performed. In addition, the right atrial free wall was widely resected and the septal and inferior vena cava-tricuspid valve isthmi were cryoablated for the treatment of atrial flutter. Postoperative catheterization revealed rather high right ventricular end-diastolic pressure. However, tricuspid regurgitation disappeared with the increased cardiac output. Atrial flutter could not be induced by repetitive stimulation in the postoperative electrophysiological examination.
