Patients with chronic renal failure (CRF) who are undergoing hemodialysis are at increased risk for infective endocarditis (IE). However, outcomes of surgical treatment for IE in these patients have not been well studied. Between 1997 and 2017, 539 patients underwent surgical treatment for IE. Of these patients, 125 were undergoing hemodialysis for end-stage renal disease (ESRD), and 414 had no history of CRF. Primary end points compared in this study were short-term survival and long-term survival. Preoperatively, dialysis-treated patients had higher incidences of diabetes (43% vs 18%), hypertension (79% vs 49%), congestive heart failure (63% vs 48%), cardiogenic shock (13% vs 5.3), and sepsis (29% vs 18%) (all P < .05). Postoperatively, they experienced higher rates of prolonged mechanical ventilation (54% vs 22%), pneumonia (17% vs 5.6%), sepsis (6.4% vs 1.0%), cardiac arrest (7.2% vs 1.7%), gastrointestinal events (14% vs 5.1%), and operative mortality (14% vs 5.8%) (all P < .05). The 5- and 10-year survival rates were significantly worse in the dialysis-treated group at 29% and 16%, respectively, compared with 72% and 53% in the patients who did not have CRF (P < .001). ESRD was a risk factor for both short-term mortality (odds ratio, 2.0) and long-term mortality (hazard ratio, 2.7). Rates of reoperation in dialysis-treated patients were very low: 5- and 10-year incidences were 0% and 2.0%, respectively. In patients with ESRD and IE, poor postoperative outcomes emphasized the importance of prevention and raised the question whether indications for surgical treatment in the general population are appropriate for patients who are dialysis dependent. Additionally, low rates of reoperation supported the use of bioprosthetic valves in these patients. Copyright © 2021 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.
