BTT-LVAD and subsequent heart transplantation markedly improve physical QOL in patients with advanced heart failure, while mental QOL, which is relatively preserved at baseline, remains stable throughout long-term follow-up.
Key Findings
Results
Baseline quality of life was severely impaired in the physical domain but relatively preserved in the mental domain prior to LVAD implantation.
Baseline Physical Component Summary (PCS) score was 22.9 ± 10.4
Baseline Mental Component Summary (MCS) score was 49.1 ± 15.0
QOL was assessed using the Short Form-36 (SF-36)
Study included 19 patients who underwent LVAD implantation and subsequently received heart transplantation between 2013 and 2025
Results
Physical QOL improved significantly during LVAD support, while mental QOL remained stable.
Mean duration of LVAD support was 64.1 ± 14.1 months
PCS improved from 22.9 ± 10.4 at baseline to 40.1 ± 7.1 during LVAD support (p = 0.008)
MCS remained stable during LVAD support at 52.4 ± 6.3 (p > 0.99)
Physical function was evaluated by grip strength, leg strength, 6-min walk distance (6MWD), and peak oxygen uptake
Results
Physical QOL continued to improve significantly after heart transplantation, while mental QOL remained stable.
Mean follow-up after transplantation was 33.6 ± 30.4 months
Post-transplant PCS further improved to 46.3 ± 7.9 (p = 0.006 compared to LVAD period)
Post-transplant MCS remained stable at 53.3 ± 5.8 (p = 0.466)
23 of 95 patients who underwent LVAD implantation subsequently received heart transplantation; 19 were included after excluding 4 with incomplete data
Results
Post-transplant physical QOL showed positive but non-significant correlations with objective physical function measures.
Physical function measures assessed included grip strength, leg strength, 6-min walk distance, and peak oxygen uptake
Correlations between post-transplant PCS and physical function measures were described as 'positive but non-significant'
No specific correlation coefficients or p-values for individual correlations were reported in the abstract
Discussion
Despite stable overall mental well-being, device- and transplant-specific psychological burdens may persist and should be addressed as part of comprehensive long-term care.
Mental QOL was relatively preserved at baseline (MCS 49.1 ± 15.0) and remained stable throughout all phases of follow-up
Authors note that stable MCS scores do not preclude the presence of specific psychological burdens related to the device or transplant process
The authors suggest these psychological concerns 'should be addressed as part of comprehensive long-term care'
Prolonged LVAD support duration (mean 64.1 ± 14.1 months) was attributed partly to donor shortage in Japan
Background
In Japan, prolonged LVAD support due to donor shortage creates a context of long-term bridge-to-transplant (BTT) use with uncertain QOL outcomes.
95 patients underwent LVAD implantation at the institution from 2013 to 2025
Of those, 23 subsequently received heart transplantation
Mean LVAD support duration was 64.1 ± 14.1 months, which is notably long compared to many international centers
The study was motivated by uncertainty around long-term QOL outcomes in this prolonged BTT context
What This Means
This research examined how quality of life (QOL) changes over time in patients with severe heart failure who received a left ventricular assist device (LVAD) — a mechanical heart pump — and later underwent a heart transplant. The study followed 19 patients at a Japanese hospital between 2013 and 2025, measuring both physical and mental aspects of QOL at three timepoints: before LVAD implantation, during LVAD support (which lasted an average of over 5 years due to limited organ donation in Japan), and after heart transplantation.
The study found that before receiving an LVAD, patients had severely reduced physical quality of life but relatively normal mental quality of life. Physical QOL improved significantly once the LVAD was implanted and continued to improve further after heart transplantation. Mental QOL, which started at a near-normal level, stayed stable throughout — neither worsening nor improving at any stage. Physical fitness measures like grip strength and walking distance showed positive trends after transplantation, though these were not statistically significant in this small sample.
This research suggests that both LVAD therapy and heart transplantation offer meaningful improvements in how physically capable and comfortable patients feel in daily life, even after years of living with a mechanical heart pump. However, the authors caution that stable mental health scores may mask specific emotional burdens tied to living with a device or going through transplantation, and that psychological support should be a routine part of care for these patients. The findings are particularly relevant in countries like Japan where patients may spend many years waiting for a donor heart while supported by an LVAD.
