  • 1

    Heart transplantation is the gold standard for end-stage heart failure, but obesity often disqualifies patients from eligibility.

  • 2

    Bariatric surgery, particularly laparoscopic sleeve gastrectomy, is being explored to improve transplant candidacy in obese patients with LVADs.

  • 3

    This study compares simultaneous LVAD implantation and LSG versus interval LSG in patients with end-stage heart failure and obesity.

  • 4

    The primary outcome showed lower sleeve-related complications in the simultaneous LVAD/LSG group compared to the interval group (7.4% vs. 17.4%).

  • 5

    The study included 77 patients, with 54 undergoing simultaneous procedures and 23 having interval LSG after LVAD implantation.
