The durability of the Starr-Edwards（SE）mitral caged-disk valve, model 6520, is not clearly known. We reported that SE mitral caged-disk valves implanted ＞20 years previously should be carefully followed up, and that SE caged-disk valves implanted ＞30 years previously should be electively replaced with modern prosthetic valves in our experience. We found the removed valve 39 years after implantation, which seemed minimal structural deterioration. The patient was discharged on the 10th postoperative day without any complications.
