Can we accept donors who have suffered a resuscitated cardiac arrest?

Abstract

Introduction and aims: The shortage of donor organs has prompted increased acceptance of hearts from donors with more comorbidities. With increasing frequency, hearts are being offered from patients who have undergone a resuscitated cardiac arrest (RCA). Our aim was to compare the rate of complications in the postoperative and follow-up periods, depending on whether the transplanted organ came from a donor who had undergone an RCA.

Materials and methods: We included all 604 heart transplantations (HTs) performed in our center from 1987 to 2009, including 25 recipients who received an organ from a donor who had undergone RCA. We considered RCA to be an in-hospital cardiac arrest that was resuscitated from the onset, with a duration of <30 minutes, and with total recovery of cardiac and hemodynamic function. We analyzed ischemia time, incidence of acute graft failure (AGF), intubation period, recovery room stay, and long-term survival. The statistical methods were Student t and chi-square tests.

Results: There were no differences in baseline characteristics, except that patients in the RCA group were younger (47±13 vs 51±11 years; P=.50). There were also no differences between the RCA group and the other patients in ischemia time (151±50 vs 154±53 minutes; P=.826), incidence of AGF (33% vs 24.7%; P=.311), hours of intubation (76±204 vs 72±249; P=.926), days of recovery room stay (6±7 vs 8±6; P=.453), or survival after HT (53±54 vs 53±52 months; P=.982).

Conclusions: Patients receiving a heart from a patient with an in-hospital RCA and subsequent hemodynamic stability have a similar outcomes to other HT patients.
