    BackgroundAn increasing number of patients on left ventricular assist device (LVAD) support are requiring non-cardiac surgical (NCS) procedures. We reviewed our experience with the management of patients on continuous flow (CF) LVAD support undergoing NCS.MethodsFrom March 2006 through March 2011, 86 patients with chronic heart failure underwent implantation of a HeartMate II (Thoratec Corp, Pleasanton, CA) LVAD. Clinical records of these patients were reviewed to identify patients who underwent NCS while on LVAD support, with a focus on peri-operative death, bleeding, thrombosis, and device malfunction, as well as management of pre-operative anti-coagulation.ResultsWhile on CF-LVAD support, 20 patients underwent 25 NCSs, comprising 13 major and 12 minor procedures. Operations were performed electively in 22 and as emergencies in 3. No peri-operative deaths, thromboembolic complications, or device malfunctions occurred. The incidence of bleeding requiring transfusion of packed red blood cells was 36.0%, including 25% of patients undergoing minor NCSs and 46.2% undergoing major NCSs (p = 0.004). All bleeding complications occurred in patients on both warfarin and aspirin pre-operatively. The only significant differences between patients who did and did not require transfusion were pre-operative warfarin use and significantly higher pre-operative international normalized ratio in the transfused group (1.9 ± 0.4 vs 1.4 ± 0.3; p = 0.008).ConclusionsNon-cardiac operations can be performed safely in patients with CF-LVADs. It may possible to reduce peri-operative bleeding by lowering pre-operative anti-coagulation goals, especially before major surgery. However, additional analysis is required to determine if this can be performed safely.Copyright © 2012 International Society for Heart and Lung Transplantation. Published by Elsevier Inc.
