Primary neuraxial anesthetic for elective total knee arthroplasty in patient with left ventricular assist device.

Abstract

There is a rising number of patients with left ventricular assist devices (LVADs) undergoing non-cardiac procedures, both emergent and elective. Historically, anesthetic options for these patients have been limited to general anesthesia. Limited data exists for the use of neuraxial anesthesia in patients with LVADs despite its common use in orthopedic procedures for non-LVAD patients. Given the benefits of neuraxial anesthesia and the rising population of LVAD patients undergoing elective procedures, a better understanding of LVAD patients' candidacy for neuraxial anesthesia needs further investigation. We report the case of a patient with an LVAD who successfully underwent a total knee arthroplasty with neuraxial anesthesia at a tertiary academic center. Preoperative transthoracic echo demonstrated stable cardiac function and an ejection fraction of 10-15% with a HeartMate 3 LVAD. The primary anesthetic was a lumbar epidural that was slowly titrated to a surgical anesthetic level and an adductor canal peripheral nerve catheter was placed preoperatively for postoperative analgesia. The patient remained hemodynamically stable throughout the case, with a perfusionist monitoring the LVAD's function intraoperatively, and tolerated the anesthetic well. His postoperative course was uneventful. Patients with LVADs should be considered candidates for neuraxial anesthesia with appropriate preoperative planning and perioperative management.
