We report a case of severe hemolysis and pulmonary valve insufficiency (PI) following right ventricular support using a paracorporeal pneumatic pump (Abiomed, Danvers, MA, USA). We speculate that the high velocity jet of blood emanating from the outflow cannula caused turbulence above the pulmonary valve, leading to PI and hemolysis. Despite the growing number of implanted ventricular assist devices, we could find no report in the literature describing pulmonary valve insufficiency secondary to right ventricular assist device (RVAD) placement. Fortunately, in this case, right ventricular function recovered sufficiently after seven days of support, allowing explantation of the device and resolution of PI and hemolysis.
我们报告了一例在使用体外气动泵(美国马萨诸塞州丹弗斯市的Abiomed公司生产)进行右心室支持后出现严重溶血和肺动脉瓣关闭不全(PI)的病例。我们推测,流出插管喷出的高速血流在肺动脉瓣上方造成湍流,导致PI和溶血。尽管植入心室辅助装置的数量不断增加,但我们在文献中未发现描述因右心室辅助装置(RVAD)植入继发肺动脉瓣关闭不全的报告。幸运的是,在本例中,经过七天的支持,右心室功能充分恢复,从而可以移除该装置,PI和溶血问题也得以解决。
