Background Basic and advanced cardiac life support guidelines do not address resuscitation of patients with continuous-flow (CF) left ventricular assist devices (LVADs). As the population of LVAD patients increases, it becomes important to understand how to provide emergency care to such patients.
Methods and Results We retrospectively reviewed a consecutive series of patients with an implanted CF-LVAD who had an in-hospital cardiopulmonary arrest at our medical center from January 2011 to October 2013. We compared them with a matched cohort of patients without LVADs who had an in-hospital cardiopulmonary arrest during the same time period. Code documentation was used to determine arrest characteristics, perfusion assessment techniques, and time to cardiopulmonary resuscitation (CPR) initiation. There were 415 in-hospital arrests during the study period, and 4% (n = 16) occurred in patients with CF-LVADs. Response teams used various approaches to assess arterial perfusion, including palpation or Doppler of the arterial pulse and measurement of blood pressure by Doppler or arterial line. Nine of the 16 patients required CPR, but only 5 (56%) received CPR in <2 minutes. In the control group (n = 32) of patients without an LVAD, 22 received CPR, which was initiated within 2 minutes in all (100%) of the patients.
Conclusions Cardiopulmonary arrests in LVAD patients accounted for 4% of all arrests in our center. We identified important time delays in CPR initiation, highlighting the need to develop resuscitation guidelines for this patient population.
