Aortic valve insufficiency may occur in a number of backgrounds. A unique etiology is illustrated in a 53-year-old man with terminal cardiac failure due to ischemic heart and aortic valvular disease. Nodular calcification complicated a congenital bicuspid valve and caused erosion through a valve cusp, producing a chronic cusp defect and valvular insufficiency.
主动脉瓣关闭不全可能在多种情况下发生。一名53岁因缺血性心脏病和主动脉瓣疾病导致终末期心力衰竭的男性患者展示了一种独特的病因。结节状钙化使先天性二叶式瓣膜复杂化，并导致瓣膜尖被侵蚀，形成慢性瓣膜尖缺损和瓣膜关闭不全。
