Right heart failure (RHF) was significantly associated with increased mortality and a higher incidence of postoperative acute kidney injury (AKI), a recent study found. The study analyzed the incidence of early and late RHF in patients with left ventricular assist devices and associated morbidity, mortality, and independent predictors of RHF. Researchers found:
- After retrospectively analyzing records of 526 patients with chronic heart failure who underwent continuous-flow left ventricular assist device (CF-LVAD) implantation, 147 (28%) developed RHF (early RHF, n=87, 16.5%; late RHF, n=74, 14.4%).
- Patients with RHF or late RHF had higher mortality than those without RHF.
- Patients with RHF had a higher incidence or AKI.
- Device type did not affect the incidence of early, late, or overall RHF.
- RHF decreased the success rate of bridging patients to transplantation when an right ventricular assist device (RVAD) was required.
