Objectives To describe perioperative management of patients with left ventricular assist devices (LVAD) in noncardiac procedures. Design Survey of (1) respondent demographic characteristics, (2) anesthetic practices for LVAD patients having endoscopies, and (3) low-risk surgeries requiring general anesthesia. Setting Internet-based. Participants Society of Cardiovascular Anesthesiologists membership. Interventions None. Measurements and Main Results Inpatient endoscopic procedures were done mainly in the endoscopy suite (71.7%) by a solo practitioner or 1:1 staffing ratio 59% of the time. LVAD-specific support personnel were present in more than 80% of all procedures. Both endoscopy and surgical patients used post-anesthesia recovery units and intensive care units for recovery; however, compared with endoscopy patients, surgical patients recovered in the ICU more frequently (45.5% v 29.1%, p<0.001). In addition, 18% of endoscopy patients recovered on site. Regarding patient monitoring, more than 90% of responders used electrocardiogram, pulse oximetry, end-tidal CO2, and blood pressure monitors on LVAD patients. Responders reported using arterial catheters to monitor blood pressure in 49% of endoscopy cases and 71% of surgical patients. The reported use of invasive monitors by individual clinicians was related inversely to institutional LVAD volume (p = 0.04 and p = 0.01 in endoscopy and surgical procedures, respectively). Conclusions This survey found heterogeneity in hospital resource utilization for noncardiac LVAD procedures. There was a decrease in the use of invasive monitors with increased institutional LVAD volume in both endoscopy and surgical procedures.
