The number of patients with left ventricular assist devices (LVADs) is increasing and development of optimal resuscitative strategies is becoming increasingly important. Despite a lack of evidence, many device manufacturers and hospitals have recommended against performing chest compressions because of fear of cannula dislodgment or damage to the outflow conduit.
A recent retrospective analysis of outcomes in LVAD patients who received chest compressions for cardiac arrest did not support the theory that LVADs would be harmed by conventional resuscitation algorithms.
The study was a limited case series of only 8 LVAD patients over a 4 year period. All patients received compressions and device integrity was subsequently assessed by blood flow data from the LVAD control monitor or by examination on autopsy. Although more research is necessary to determine the utility and effectiveness of compressions in this population, none of the patients in this study had cannula dislodgment and half of the patients had return of neurologic function.
