Expanding Heart Transplant in the Era of Direct-Acting Antiviral Therapy for Hepatitis C.

Importance: For patients awaiting heart transplant, hepatitis C-positive donors offer an opportunity to expand the donor pool, shorten wait times, and decrease wait-list mortality. While early reported outcomes among few heart transplant recipients have been promising, knowledge of 1-year outcomes in larger cohorts of patients is critical to shared decision-making with patients about this option.

Objective: To better define the association of hepatitis C-positive donors with heart transplant volumes, wait-list duration, the transmission and cure of donor-derived hepatitis C, and morbidity and mortality at 1 year.

Trends in Renal Function Among Heart Transplant Recipients of Donor-Derived Hepatitis C Virus.

Donor-derived hepatitis C (dd-HCV) infection may increase the risk of renal impairment (RI) among heart transplantation (HT) recipients. Sofosbuvir, an integral component of HCV direct-acting antivirals (DAAs) has also been linked to RI. To date, no study has examined the trends in renal function for HT recipients of dd-HCV infection and assessed safety and efficacy of Sofosbuvir-based DAAs.

Center volume and post-transplant survival among adults with congenital heart disease.

Background: The number of adult congenital heart disease (ACHD) patients requiring heart transplantation (HT) continues to grow, and if they survive the first year after transplant, their long-term survival is at least equivalent to non-ACHD patients. The 1-year survival of ACHD patients with HT remains lower than non-ACHD patients. We evaluated the affect of transplant center volume on 1-year survival of ACHD patients.

Anticoagulation Reversal and Risk of Thromboembolic Events Among Heart Transplant Recipients Bridged with Durable Mechanical Circulatory Support Devices.

Anticoagulation reversal agents (ARAs) can minimize bleeding complications associated with mechanical circulatory support devices (MCSDs) explantation at the time of heart transplantation (HT); data on thromboembolic (TE) risk associated with ARAs are limited in this patient population. In this single-center study, we retrospectively analyzed 118 consecutive adults who were supported with durable MCSDs and underwent HT between May 2013 and October 2016. Patients were categorized based on intraoperative use of ARAs (recombinant factor VIIa [n=23], 4-factor prothrombin complex concentrate [n=48], or factor IX complex [n=2]) at the time of HT; these agents were used at discretion of implanting surgeons for bleeding control.

Early outcomes using hepatitis C-positive donors for cardiac transplantation in the era of effective direct-acting anti-viral therapies.

Background: Given the shortage of suitable donor hearts for cardiac transplantation, and the favorable safety and efficacy of current agents used to treat hepatitis C virus (HCV), our institution recently piloted transplantation of select patients using HCV-positive donors.

Methods: Between September 2016 and March 2017, 12 HCV-naive patients and 1 patient with a history of treated HCV underwent heart transplantation (HT) using hearts from HCV-positive donors after informed consent. Patients who acquired HCV were referred to hepatology and treated with direct-acting anti-viral therapies (DAAs).
