ABSTRACT

Combining left ventricular assist device (LVAD) implantation and longitudinal sleeve gastrectomy may enable patients with morbid obesity to lose enough weight for heart transplant eligibility. In a retrospective study, we evaluated long-term outcomes of patients with body mass indexes ≥35 who underwent LVAD implantation and longitudinal sleeve gastrectomy during the same hospitalization (from January 2013 through July 2018) and then adhered to a dietary protocol. We included 22 patients (mean age, 49.9 ± 12.5 yr; mean preoperative body mass index, 43.3 ± 6.2). Eighteen months after gastrectomy, all 22 patients were alive, and 16 (73%) achieved a body mass index of less than 35. Myocardial recovery in 2 patients enabled LVAD removal. As of October 2020, 10 patients (45.5%) had undergone heart transplantation, 5 (22.3%) were waitlisted, 5 (22.3%) still had a body mass index ≥35, and 2 (9%) had died. With LVAD support, longitudinal sleeve gastrectomy, and dietary protocols, most of our patients with morbid obesity and advanced heart failure lost enough weight for transplant eligibility. Support from physicians and dietitians can maximize positive results in these patients.

ABSTRACT

Bariatric surgery helps many morbidly obese patients lose substantial weight. However, few data exist on its long-term safety and effectiveness in patients who also have continuous-flow left ventricular assist devices and in whom heart transplantation is contemplated. We retrospectively identified patients at our institution who had undergone ventricular assist device implantation and subsequent laparoscopic sleeve gastrectomy from June 2015 through September 2017, and we evaluated their baseline demographic data, preoperative characteristics, and postoperative outcomes. Four patients (3 men), ranging in age from 32 to 44 years and in body mass index from 40 to 57, underwent sleeve gastrectomy from 858 to 1,849 days after left ventricular assist device implantation to treat nonischemic cardiomyopathy. All had multiple comorbidities. At a median follow-up duration of 42 months (range, 24-47 mo), median body mass index decreased to 31.9 (range, 28.3-44.3) at maximal weight loss, with a median percentage of excess body mass index lost of 72.5% (range, 38.7%-87.4%). After achieving target weight, one patient was listed for heart transplantation, another awaited listing, one was kept on destination therapy because of positive drug screens, and one regained weight and remained ineligible. On long-term follow-up, laparoscopic sleeve gastrectomy appears to be safe and feasible for morbidly obese patients with ventricular assist devices who must lose weight for transplantation consideration. Additional studies are warranted to evaluate this weight-loss strategy after transplantation and immunosuppression.

ABSTRACT

OBJECTIVE: To compare mortality, nonfatal coronary heart disease (CHD), and congestive heart failure (CHF) risk across BMI categories in white, African American, and Hispanic women, with a focus on severe obesity (BMI ≥ 40), and examine heterogeneity in weight-related CHD risk. METHODS: Among 156,775 Women's Health Initiative observational study and clinical trial participants (September 1993-12 September 2005), multivariable Cox models estimated relative risk for mortality, CHD, and CHF. CHD incidence was calculated by anthropometry, race, and cardiovascular risk factors (CVRF). RESULTS: Mortality, nonfatal CHD, and CHF incidence generally rose with BMI category. For severe obesity versus normal BMI, hazard ratios (HRs, 95% confidence interval) for mortality were 1.97 (1.77-2.20) in white, 1.55 (1.20-2.00) in African American, and 2.59 (1.55-4.31) in Hispanic women; for CHD, HRs were 2.05 (1.80-2.35), 2.24 (1.57-3.19), and 2.95 (1.60-5.41) respectively; for CHF, HRs were 5.01 (4.33-5.80), 3.60 (2.30-5.62), and 6.05 (2.49-14.69). CVRF variation resulted in substantial variation in CHD rates across BMI categories, even in severe obesity. CHD incidence was similar by race/ethnicity when differences in BMI or CVRF were accounted for. CONCLUSIONS: Severe obesity increases mortality, nonfatal CHD, and CHF risk in women of diverse race/ethnicity. CVRF heterogeneity contributes to variation in CHD incidence even in severe obesity.

ABSTRACT

OBJECTIVE: to evaluate the importance of treatment of deformities caused by massive localized lymphedema (MLL) in the severely obese. METHODS: in a period of seven years, nine patients with morbid obesity and a mean age of 33 years underwent surgical resection of massive localized lymphedema with primary synthesis. This is a retrospective study on the surgical technique, complication rates and improved quality of life. RESULTS: all patients reported significant improvement after surgery, with greater range of motion, ambulation with ease and more effective hygiene. Histological analysis demonstrated the existence of a chronic inflammatory process marked by lymphomonocitary infiltrate and severe tissue edema. We observed foci of necrosis, formation of microabscesses, points of suppuration and local fibrosis organization, and pachydermia. The lymphatic vessels and some blood capillaries were increased, depicting a framework of linfangiectasias. CONCLUSION: surgical treatment of MLL proved to be important for improving patients' quality of life, functionally rehabilitating them and optimizing multidisciplinary follow-up of morbid obesity, with satisfactory surgical results and acceptable complication rates, demonstrating the importance of treatment and awareness about the disease. .


OBJETIVO: avaliar a importância do tratamento das deformidades ocasionadas pelo linfedema maciço localizado (LML) em obesos. MÉTODOS: em um período de sete anos, nove pacientes portadores de obesidade mórbida e com média etária de 33 anos, foram submetidos à ressecção cirúrgica de linfedema maciço localizado e síntese primária. Trata-se de estudo retrospectivo sobre a técnica cirúrgica empregada, incidência de complicações e melhora da qualidade de vida dos pacientes. RESULTADOS: todos os pacientes relataram expressiva melhora após o tratamento cirúrgico, apresentando maior amplitude de movimentos, com desenvoltura da deambulação e possibilidades de higiene mais efetivas. As análises histológicas demonstraram a existência de processo inflamatório crônico marcado por infiltrado linfomonocitário, acompanhado de grande edema tecidual. Foram constatados focos de necrose, formação de microabcessos, pontos de supuração e organização de fibrose local e paquidermismo. Os vasos linfáticos e alguns capilares sanguíneos apresentavam-se aumentados, definindo um quadro de linfangiectasias. CONCLUSÃO: o tratamento cirúrgico do LML mostrou-se importante para a melhora na qualidade de vida desses pacientes, reabilitando-os funcionalmente e otimizando o seguimento multidisciplinar da obesidade mórbida, com resultados cirúrgicos satisfatórios e taxas aceitáveis de complicações, demonstrando a importância do tratamento e da consciência sobre a doença. .
