Bariatric Surgery as the One Route to Achieving Donor Heart Transplantation in a Patient with a Left-Ventricular Assist Device

Abstract

Bariatric and metabolic surgery is currently the most effective procedure of achieving and maintaining weight loss. In the case under discussion, a 48-year-old male patient with heart insufficiency and an implanted left-ventricular assist device (LVAD) wanted to reduce his high BMI (48.6 kg/m2), so as to qualify for the heart transplant waiting list. According to the guidelines, he underwent all the required preoperative testing, which included psychosomatic clarifications, determination of endocrinological causes, and a nutritional consultation. During laparoscopic sleeve gastrectomy, a cardiac technician was present to support the anesthetist. After inserting 3 trocars with no complications, the greater curvature was mobilized using Medtronic’s bipolar electrothermal vessel-sealing instrument, LigaSure™. The resection was performed with an Ethicon™ endostapler. Postoperative monitoring showed no signs of hemorrhage. The patient’s BMI on the day of surgery was 46.8 kg/m2 and consecutively fell to 26.7 kg/m2 1 year after the procedure. Follow-up appointments revealed that the patient was fit and in good health. Thus, the patient’s aim of being listed on the transplant list was fulfilled, and at the time of this writing, he is ready to be matched with an organ donor. Because high-BMI patients with inserted LVADs are less likely to receive a donor graft and must remain longer on transplant waiting lists than normal-weight patients, bariatric and metabolic weight loss surgery may lead to a speedier resolution for these high-risk patients.
