Advanced heart failure patients typically have reduced renal reserve due to prolonged hemodynamic impairment and coexisting cardiorenal syndrome. This increases the risk of acute kidney injury following any type of surgical intervention. Even minimally compromised renal function can significantly increase the morbidity and mortality of these procedures. For these reasons, there is a critical need to carefully assess these risk factors in the preoperative setting, modifying them when possible in order to reduce the incidence of renal dysfunction. In cases where acute kidney injury occurs despite taking the appropriate preventative measures, a detailed understanding of the different modalities of renal replacement and the timing with which these methods are initiated can have a substantial impact on postoperative outcomes.
