We experienced an explantation of Wada-Cutter prosthetic tilting disk valve of 47 years after implantation. The patient was 53 years old female who underwent the 1st operation for Ebstein's anomaly, which included tricuspid valve replacement (TVR), closure of atrial septal defect (ASD) and posterior annulorrhaphy when she was 6 years old. She was doing well after the 1st operation without symptom,but dyspnea and systemic edema worsened recently though increased admission of diuretics. Echocardiography revealed severe tricuspid valve stenosis, severe tricuspid valve insufficiency, and increased right atrium volume. The tilting disk of the valve was almost fixed. The patient underwent repeat TVR. The explanted Wada-Cutter valve was covered by pannus the whole casing and disk. The structure of the valve was preserved but the occlusion disk was almost fixed by pannus formation, not distorted or dislodged.
