Abstract

Background: Higher rates of corrected QT (QTc) prolongation have been reported in patients with cirrhosis. The impact of liver transplantation and prescription medications on the natural history of QTc prolongation has yet to be well characterized. Methods: This was a single-center review of patients receiving (group 1) or listed for (group 2) a liver transplant during 2014. Patients in group 1 were followed prospectively from the date of transplantation to assess rates of QTc normalization posttransplant. In group 2, patients were evaluated from the date of listing up until December 2015 to assess the prevalence of QTc prolongation among liver transplant candidates. Results: In group 1, 22 (75.9%) patients with QTc intervals >460 milliseconds at the time of transplant established normal baseline QTc intervals following transplantation. The median time to this QTc normalization was 17 days. In group 2, 30 (16.9%) patients had at least 1 documented QTc interval >500 milliseconds with prevalence rates of 42.9%, 19.0%, and 10.2% in patients with natural model of end-stage liver disease scores of >30, 16 to 30, and <16, respectively (P
