An 80-year-old patient presented with a rare complication: a late coronary-cameral fistula following implantation of an Amulet (Abbott) left atrial appendage occlusion device. Microperforations from the device's anchoring tines have previously been suggested as a possible mechanism of fistula formation, a complication reported in two other cases. We propose an alternative theory of potential collateralisation of the threatened appendage from the nearby circumflex artery.
一名80岁患者出现了一种罕见的并发症：在植入Amulet（雅培）左心耳封堵装置后发生迟发性冠状动脉-心腔瘘。此前有人认为，该装置锚定尖的微穿孔可能是瘘形成的一种机制，另外两例病例也报告了这种并发症。我们提出了一种替代理论，即受威胁的心耳可能由附近的旋支动脉形成潜在侧支循环。
