Objective:

To evaluate the safety and feasibility of conducting laparoscopic sleeve gastrectomy (LSG) concurrently with left ventricular assist device (LVAD) implantation in patients with end-stage heart failure (ESHF) and obesity.

Approach:

• Study Design: A single-center retrospective cohort study assessing outcomes among adults with obesity and ESHF who received LVAD implantation.
• Patient Groups: Patients were divided into two groups: those undergoing simultaneous LVAD and LSG and those receiving interval LSG after LVAD implantation.
• Surgical Procedure: A standardized four-port laparoscopic approach was used for LSG, with postoperative care including therapeutic anticoagulation starting 12–24 hours post-surgery.
• Outcome Measures: Primary endpoint was sleeve-related morbidity within 90 days post-surgery; secondary outcomes included BMI reduction, heart transplantation rates, and hospital readmissions.

Key Findings:

• 77 individuals met inclusion criteria; 54 underwent simultaneous LVAD/LSG and 23 had interval LSG.
• The primary endpoint showed a lower incidence of sleeve-related complications in the simultaneous group (7.4%) compared to the interval group (17.4%), though this difference was not statistically significant (p = 0.23).
• Operative duration was longer for simultaneous LVAD/LSG.

Interpretation:

The findings suggest that simultaneous LVAD and LSG may be associated with a lower rate of sleeve-related complications compared to interval LSG, although the lack of statistical significance indicates that further research is needed to confirm these observations. The longer operative duration for the simultaneous procedure raises considerations regarding surgical efficiency and patient recovery. The results highlight the potential benefits of combined surgical approaches in this high-risk population, but also underscore the need for larger studies to validate these findings and establish best practices.

Limitations:

• The retrospective design may introduce selection bias.
• The small sample size limits the generalizability of results.
• There was no randomization between groups.

Conclusion:

The study indicates that simultaneous LVAD and LSG may offer a promising approach for managing obesity in patients with ESHF, potentially leading to fewer sleeve-related complications. However, the findings are tempered by the limitations of a small sample size and the retrospective nature of the study, which may affect the robustness of the conclusions. Future research should focus on larger, randomized controlled trials to better assess the safety and efficacy of this combined surgical strategy. Additionally, understanding the long-term outcomes, including weight loss sustainability, heart function improvement, and overall survival rates, will be crucial in determining the best surgical approach for this vulnerable population.
