Compassionate Deactivation of Ventricular Assist Devices in Children with Heart Failure

End-of-Life in Pediatric Patients Supported by Ventricular Assist Devices: A Network Database Cohort Study

OBJECTIVES

Most pediatric patients on ventricular assist device (VAD) survive to transplantation. Approximately 15% will die on VAD support, and the circumstances at the end-of-life are not well understood. We, therefore, sought to characterize patient location and invasive interventions used at the time of death.

DESIGN

Retrospective database study of a cohort meeting inclusion criteria.

SETTING

Thirty-six centers participating in the Advanced Cardiac Therapies Improving Outcomes Network (ACTION) Registry.

PATIENTS

Children who died on VAD therapy in the period March 2012 to September 2021.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Of the 117 of 721 patients (16%) who died on VAD, the median (interquartile range) age was 5 years (1-16 yr) at 43 days (17-91 d) postimplant. Initial goals of therapy were bridge to consideration for candidacy for transplantation in 60 of 117 (51%), bridge to transplantation in 44 of 117 (38%), bridge to recovery 11 of 117 (9%), or destination therapy (i.e., VAD as the endpoint) in two of 117 (2%). The most common cause of death was multiple organ failure in 35 of 117 (30%), followed by infection in 12 of 117 (10%). Eighty-five of 92 (92%) died with a functioning device in place. Most patients were receiving invasive interventions (mechanical ventilation, vasoactive infusions, etc.) at the end of life. Twelve patients (10%) died at home.

CONCLUSIONS

One-in-six pediatric VAD patients die while receiving device support, with death occurring soon after implant and usually from noncardiac causes. Aggressive interventions are common at the end-of-life. The ACTION Registry data should inform future practices to promote informed patient/family and clinician decision-making to hopefully reduce suffering at the end-of-life.

Bereaved Caregiver Perspectives on the End of Life in Pediatric Patients With Ventricular Assist Devices

OBJECTIVES

Ventricular assist devices (VADs) are increasingly used in pediatric heart failure as bridges to heart transplantation, although 25% will die with VADs. Family experiences in this population are not well-described. The objective is to understand bereaved families' perspectives on VAD and end-of-life decision-making.

DESIGN

Semistructured interviews with bereaved caregivers of pediatric VAD patients.

SETTING

Tertiary children's hospital.

PATIENTS

Families of six pediatric VAD patients who died from 2014 to 2020.

INTERVENTIONS

Not available.

MEASUREMENTS AND MAIN RESULTS

Applying a grounded theory framework, interviews were coded by two independent readers using qualitative software. Themes were discussed in iterative multidisciplinary meetings. Participants were interviewed at a median 2.4 years after their child died. Three major themes emerged: 1) "lack of regret" for VAD implantation despite the outcome; 2) "caregiver-child accord" (via patient's verbal assent or physical cues) at implantation and end-of-life was important in family decision-making; and 3) development of a "local surrogate family" (medical team and peer families) provided powerful support.

CONCLUSIONS

Bereaved families' perspectives provide insight into quality decision-making for major interventions and end-of-life care in pediatric patients with chronic illness who face decisions regarding technology dependence.
