Aortic insufficiency (AI) occurs as a complication in 25% to 37% of cases that receive left ventricular assist devices (LVAD). The incidence increases after implant by 1% to 6% per month of continued support. Uncertainty remains over the appropriate management of pump speeds to help delay this deterioration (complete emptying versus allowing native ventricular function open the aortic on a regular basis). Significant AI can lead to hemodynamic impairment with adverse outcomes over time. Due to the recirculation of blood, the calculated cardiac output of the LVAD may be markedly skewed. A number of surgical techniques have been proposed for the prevention and management of AI in the setting of LVAD therapy. This chapter details the causes, treatment strategies, and outcomes associated with this complication.
