Abstract Objectives: Patients with end-stage heart failure (ESHF) treated with ventricular assist devices (VADs) tend to gain weight after implantation, which is associated with higher complication rates and is a contraindication for heart transplantation (HT). The objective was to analyze the outcomes of obese patients with ESHF and VADs who under‑ went laparoscopic sleeve gastrectomy (LSG) at Ochsner Medical Center in New Orleans, which is the only program performing VADs and HT in the State of Louisiana, and also one of the largest VAD centers in the USA. Data description: This dataset contains detailed baseline, perioperative, and long-term data of patients with VADs undergoing LSG. These variables were collected retrospectively from electronic medical records. Patients who achieved ≥ 50% excess BMI loss, BMI ≤ 35 kg/m2, listing for HT, HT, or myocardial recovery were identified and the timing to each of these milestones was documented. These data can be used alone or in combination with other datasets to achieve a larger sample size with more power for further analysis of these variables, which include the most important, standard, and objective bariatric and ESHF outcomes of patients with VADs undergoing LSG. Elabora‑ tion of composite outcomes is feasible.

Nowadays, many patients undergo VAD implantation as a bridge to heart transplantation (HT), and remain on VAD support while awaiting availability of a healthy compatible heart. In other cases, patients undergo VAD implantation after being rejected for HT due to significant obesity (BMI ≥ 35 kg/m2) [1]. *Correspondence: [email protected] 1 The John Ochsner Heart and Vascular Institute, Ochsner Clinic Foundation, New Orleans, LA, USA Full list of author information is available at the end of the article
After VAD implantation, patients tend to feel better with appetite improvement, leading to increased caloric intake. Although exercise tolerance often improves too, it remains limited when compared to healthy subjects [2]. These factors, in addition to other comorbidities like depression, lead to weight gain after VAD implantation, especially in those patients with BMI
