Abstract:

To summarize the nursing experience of a patient with cardiac resynchronization therapy defibrillator （CRT-D） implantation who was about to deplete battery due to repeated discharge after implantation and underwent left ventricular assist device implantation combined with cryoablation. Key points of care were as follows. To begin with，we actively managed arrhythmias and electric storm. Secondly，we carried refined capacity management to avoid water and sodium retention. Thirdly，we formulated personalized anticoagulation programs to reduce the risk of bleeding and thrombosis. Then，the pump line infection should be prevented as early as possible. At the whole stage，we provided psychological counseling to improve emotional state. After discharge，regular follow-up was carried out through online and offline method to ensure quality of life in the long term. After careful treatment and nursing care，23 days after surgery，the patient was discharged smoothly，and good follow-up after discharge.
