Clinical Report: Comparative Analysis of Simultaneous and Interval Sleeve Gastrectomy

Overview

This study evaluates the safety and feasibility of simultaneous sleeve gastrectomy (LSG) and left ventricular assist device (LVAD) implantation in patients with end-stage heart failure. It compares outcomes with those undergoing interval LSG after LVAD implantation.

Background

End-stage heart failure (ESHF) patients often face eligibility challenges for heart transplantation, particularly due to obesity. A body mass index (BMI) ≥35 kg/m² is a significant contraindication, leading to increased perioperative complications. Bariatric surgery, specifically LSG, is being explored as a strategy to facilitate weight loss and improve transplant candidacy in this population.

Data Highlights

In a cohort of patients undergoing simultaneous LSG and LVAD implantation, the average BMI was 38 kg/m², with a mean age of 55 years. The length of hospital stay post-surgery averaged 10 days, and the 30-day readmission rate was reported at 5%. In contrast, patients undergoing interval LSG after LVAD implantation had a higher average BMI of 40 kg/m², with a mean age of 60 years, and a longer average hospital stay of 14 days, with a 30-day readmission rate of 15%.

Key Findings

• Simultaneous LSG and LVAD implantation may reduce cumulative surgical risks.

• Patients undergoing simultaneous procedures may experience earlier weight loss.

• Interval LSG requires additional hospital admissions and operations, increasing overall risk.

• Management of perioperative anticoagulation is critical to mitigate complications.

• Patients with BMI ≥35 kg/m² face longer wait times and higher post-transplant mortality.

Clinical Implications

The findings indicate that performing LSG concurrently with LVAD implantation may streamline the treatment process for obese ESHF patients.

Conclusion

The study supports the feasibility of simultaneous LSG and LVAD implantation, demonstrating that this approach may offer significant advantages over the interval procedure. By reducing the overall surgical burden and hospital stay, simultaneous procedures can enhance patient outcomes and facilitate more timely weight loss, which is critical for improving transplant eligibility. Additionally, the findings highlight the importance of careful perioperative management, particularly regarding anticoagulation, to minimize complications. Overall, this study suggests that integrating bariatric surgery with cardiac support interventions could represent a paradigm shift in the management of obese patients with end-stage heart failure, ultimately leading to improved survival rates and quality of life.
