The New York Heart Association class IV heart failure patient represents a very sick patient population with a poor 6-month survival rate. With appropriate selection and timing, left ventricular assist devices can provide improved outcomes while these patients are supported for bridge to heart transplant or destination therapy. As the number of heart failure patients supported by left ventricular assist devices increases, physicians will need to be familiar with postoperative chronic issues (such as right ventricular failure, infection, hypertension, atrial fibrillation, bleeding, and thromboembolic events) that can affect the function of these devices.
纽约心脏协会（NYHA）心功能 IV 级心力衰竭患者代表了一个病情非常严重的患者群体，其 6 个月生存率较低。通过适当的选择和时机，左心室辅助装置（LVAD）可以在这些患者接受心脏移植桥接或终点治疗时提供更好的结果。随着接受左心室辅助装置支持的心力衰竭患者数量的增加，医生需要熟悉术后的慢性问题（如右心衰竭、感染、高血压、心房颤动、出血和血栓栓塞事件），这些问题可能会影响这些装置的功能。
