Discharge outcomes in patients with paracorporeal biventricular assist devices

The effect of paracorporeal pulsatile biventricular assist devices on allosensitization in adults: A comparison with left ventricular assist devices

Ventricular assist devices (VADs) have been associated with the development of anti-HLA antibodies ('allosensitization'), but data on devices providing biventricular support in adults are limited. We sought to characterize differences in anti-HLA antibody formation in adult patients receiving left- (LVAD) versus biventricular- (BiVAD) assist devices as bridge to transplantation (BTT) by retrospectively reviewing the records of adult patients who have undergone VAD implantation at our institution. We assessed 82 patients supported with a pulsatile-flow paracorporeal BiVAD and compared them with 40 patients receiving LVAD till 2018. Forty-eight (58.5%) of the BiVAD and 23 (57.5%) of the LVAD patients were eventually transplanted (p = 0.91) with an average time to transplantation 559 and 598 days, respectively (p = 0.73). Evidence of sensitization pre-VAD was found in 11.0% of the BiVAD patients and 15.0% of the LVAD ones (p = 0.53); these percentages rose to 43.9% (p < 0.001) and 40.0% (p = 0.01), respectively. The post-VAD sensitization status was not significantly different between the BiVAD and the LVAD group (p = 0.68). De novo sensitization was comparable between the two groups (p = 0.55). Post-transplantation outcomes regarding rejections and cardiac allograft vasculopathy were also similar. Conclusively, BiVAD- and LVAD- induced allosensitization do not appear to differ significantly.

Paving a Road Home: Developing Education for a Pediatric Home-Going VAD Program

The objective was to create a multidisciplinary education plan for discharge home following implantation of a ventricular assist device (VAD) in pediatrics. Educational program was developed for the local community: emergency department, emergency medical services, medical transport team, as well as, the pediatric patient and their caregivers. Education geared to the individual learner included both lecture and hands-on training. A direct line for family and local providers to speak directly with a VAD-trained physician 24/7 was also created. Patient and caregivers required to 1) perform 10 supervised power exchanges; 2) qualify written quizzes on the controller, battery charger, alarms, and troubleshooting; 3) perform 10 supervised dressing changes; 4) pass simulation session responding correctly to alarm scenarios; and 5) take both an on-campus and off-campus field trip unaccompanied by support staff. Once the education plan is complete and the patient is medically stable, they are considered ready for discharge. From a mechanical support perspective, discharge home of a medically complex pediatric patient on a durable VAD can be accomplished safely, even in a low volume center, with attention to detail, creation of a robust education plan, and close partnership between the VAD team, the family, and the community.

Team-Based Care for Outpatients with Heart Failure

Management of heart failure requires a multidisciplinary team-based approach that includes coordination of numerous team members to ensure guideline-directed optimization of medical therapy, frequent and regular assessment of volume status, frequent education, use of cardiac rehabilitation, continued assessment for the use of advanced therapies, and advance care planning. All of these are important aspects of the management of this complex condition.
