Abstract:

To summarize the perioperative nursing experience of 20 patients with complex coronary artery lesions and reduced left ventricular ejection fraction who underwent percutaneous coronary intervention（PCI） with Impella left ventricular assist device（Impella-LVAD） support. Key nursing points are as follows：prior to surgery，multidisciplinary collaboration was established to conduct comprehensive assessments；stable hemodynamics was maintained throughout the perioperative period with precise volume management；during surgery，the operation of auxiliary de-vices was standardized，and related complications were actively prevented；postoperatively，early warning signs of ven-tricular electrical storms were promptly identified；rapid emergency protocols were initiated；bundled hydration inter-vention pathways were implemented to protect renal function，and progressive early rehabilitation was conducted to improve clinical prognosis. Through meticulous treatment and nursing care，all 20 patients achieved a 100% proce-dural success rate，and all were discharged successfully following recovery. No major adverse cardiovascular events oc-curred during the 3-month follow-up period，indicating favorable patient outcomes.
