George and colleagues report their experience with a non-transplant left
ventricular assist device program (1). This manuscript spans a decade’s
experience with LVADs and clearly demonstrates that LVAD therapy is
possible in centers without a heart transplant program. 100 LVADs were
placed during this period. The positive findings from this report
include that as volume increased, the complications of right heart
dysfunction and bleeding decreased. Noteworthy is that 85 of the 100
patients were implanted with a fully magnetically levitated ventricular
assist device. Given the superior performance of a fully magnetically
levitated device to a rotary pump (2) these findings are relevant for
all contemporary centers with LVAD programs.
The authors importantly sought the resources of a transplant center to
ensure that patients who were offered LVAD in their non-transplant
center were indeed not candidates for cardiac transplantation. In
addition to this fundamental necessity, three features are necessary for
a successful non-transplant LVAD program. Firstly, the institution must
offer robust infrastructure and support. Secondly there must be a strong
surgeon-leader dedicated to overseeing the program. Lastly,
cardiologists who are dedicated to heart failure are essential to guide
patients to this therapy.
The extension of LVAD therapy to patients in non-transplant centers is
essential for durable mechanical circulatory support to remain as a
vital part of advanced therapies for heart failure. VADs will continue
to play an important role in the management of end-stage heart failure
for patients who are not eligible for cardiac transplantation. The 2020
Society of Thoracic Surgeons INTERMACs report now offers patients a
5-year survival of 45%(3). The survival of patients with LVADs
continues to increase. The data in this current report offer a new
perspective and increased access to LVAD therapy for patients with end
stage heart failure.
