“…At the time of LVAD implantation there was a hope that we would provide our patient with time to lose weight and become a better transplant candidate. The current evidence does not support this assumption since obese patients with LVAD seem to gain weight . The inability of patients to lose weight conservatively supports the indication for bariatric surgery.…”

“…The current evidence does not support this assumption since obese patients with LVAD seem to gain weight. 4 The inability of patients to lose weight conservatively supports the indication for bariatric surgery. It can be performed either simultaneously, during LVAD implantation, or staged as performed in our case.…”

“…This improvement is attributed to the effect of weight loss on cardiac morphology, hemodynamics, and systolic function . Obesity is not considered a contraindication for LVAD implantation, and implantation of long‐term mechanical support for obese patients with CHF is a viable option . Reports on treatment of advanced heart failure with bariatric surgery are scant and are usually limited to case reports.…”

“…2 Obesity is not considered a contraindication for LVAD implantation, 3 and implantation of long-term mechanical support for obese patients with CHF is a viable option. 4 Reports on treatment of advanced heart failure with bariatric surgery are scant and are usually limited to case reports. The decision to implant an LVAD in an obese patient with CHF as a bridge to transplant and weight loss is the subject of this case report.…”

“…As with other CF-LVAD recipients, significant weight loss may be difficult to achieve, despite a presumed improvement in heart failure symptoms. 7,8 In the BMD population, in which the capacity to exercise is predominantly the result of the skeletal myopathy, improvements in heart failure symptoms after LVAD implantation may result in improved appetite After HM2 implantation, the patient experienced rapid weight gain, coincident with a decline in functional capacity. He eventually underwent LVAD pump exchange secondary to a driveline fracture that occurred in the context of repeated falls.…”

Obesity and Premature Loss of Mobility in Two Adolescents with Becker Muscular Dystrophy After HeartMate II Implantation

et al. 2016

Weight gain is common after implantation of continuous-flow ventricular assist devices. Obesity can have a significant negative impact on mobility. For adolescents with Becker muscular dystrophy (BMD), for whom the ability to ambulate often persists into the mid-3rd decade, preservation of functional ability is critical. We report two cases of Thoratec HeartMate II left ventricular assist device (LVAD) implantation in adolescents with BMD for whom postoperative weight gain contributed significantly to an accelerated loss of ambulation and, in one case, driveline fracture in the context of repeated falls. As LVADs become an increasingly common therapy for endstage heart failure in adolescents with BMD, care must be focused not only on maintenance of device functionality, but also on management of aggressive weight, and preservation of ambulation, and skeletal muscle strength.

Obesity is a risk factor for kidney, liver, heart, and pulmonary diseases, as well as failure. Solid organ transplantation remains the definitive treatment for the end-stage presentation of these diseases. Among many criteria for organ transplant, efficient management of obesity is required for patients to acquire transplant eligibility. End-stage organ failure and obesity are 2 complex pathologies that are often entwined. Metabolic and bariatric surgery before, during, or after organ transplant has been studied to determine the long-term effect of bariatric surgery on transplant outcomes. In this review, a multidisciplinary group of surgeons from the Society of American Gastrointestinal and Endoscopic Surgeons and the American Society for Transplant Surgery presents the current published literature on metabolic and bariatric surgery as a therapeutic option for patients with obesity awaiting solid organ transplantation. This manuscript details the most recent recommendations, pharmacologic considerations, and psychological considerations for this specific cohort of patients. Since level one evidence is not available on many of the topics covered by this review, expert opinion was implemented in several instances. Additional high-quality research in this area will allow for better recommendations and, therefore, treatment strategies for these complex patients.
