はじめに　12年前より無症候性に経過した大動脈弁位乳頭状線維弾性腫の1例を経験した．発育速度に関する報告は限られているため報告する．

We experienced a case of papillary fibroelastoma of aortic valve, which had been located for preoperative 12 years without any symptom. We could assess tumor growth rate of 0.17 mm/year. Because of recent reports of recurrence, close follow-up should be continued.
