We present the case of a 24 year-old patient that developed massive hemolysis shortly after percutaneous left ventricular assist device, Impella 2.5, was placed. The hemolysis occurred without device alarm while the device was in the correct position. Further investigation of the device revealed fiber wrapped around the tip of the device, as a culprit. This case emphasizes on the special caution applied during device preparation to minimize the possible adverse events.
我们报告了一例24岁患者的病例，该患者在经皮植入左心室辅助装置Impella 2.5后不久发生了大量溶血。溶血发生时装置处于正确位置且未发出警报。对该装置的进一步检查发现，装置尖端缠绕有纤维，这是导致溶血的原因。该病例强调了在装置准备过程中应格外小心，以尽量减少可能的不良事件。
