BACKGROUND: Obesity is a chronic disease and a risk factor for heart failure. In end-stage heart failure, heart transplantation may be the only available treatment option, but obesity is a contraindication for this treatment because of its unfavourable prognosis. Bariatric surgery and its subsequent weight loss may affect the indication for transplantation in patients with heart failure and morbid obesity. CASE DESCRIPTION: A 46-year-old patient with morbid obesity and heart failure underwent gastric sleeve resection in preparation of a heart transplantation...

BACKGROUND CONTEXT: Postoperative Urinary Retention (POUR) is a very common post-operative complication of all surgeries (5 - 70%) that may lead to complications such as urinary tract infection (UTI), bladder over-distention, autonomic dysregulation, and increased postoperative length of stay (LOS). Within the field of spine surgery, the reported incidence of POUR is highly variable (5.6 - 38%). Lack of clear stratification of surgical level, spinal pathology, and inadequate sample size is a major limitation of available studies concerning POUR following spine surgery that may lead to inconsistency in the incidence of POUR and the ability to model its occurrence and consequences...

Left ventricular noncompaction cardiomyopathy (LVNC) is characterized by compact and trabecular layers of the left ventricular myocardium. This cardiomyopathy may occur with congenital heart disease (CHD). Single cases document co-occurrence of LVNC and heterotaxy, but no data exist regarding the prevalence of this association. This study sought to determine whether a non-random association of LVNC and heterotaxy exists by evaluating the prevalence of LVNC in patients with heterotaxy. In a retrospective review of the Indiana Network for Patient Care, we identified 172 patients with heterotaxy (69 male, 103 female)...

OBJECTIVES: Central veno-arterial extracorporeal membrane oxygenation (C-VA-ECMO) provides temporary cardiorespiratory support for patients in heart failure who cannot be weaned from cardiopulmonary bypass successfully. Outcomes are influenced by the reversibility of the initial insult and complications of the technique. METHODS: The authors reviewed their single-center experience over the last 8 years to inform future practice. The study included all patients supported with C-VA-ECMO after cardiothoracic surgery between January 2008 and July 2016...

OBJECTIVE: Treatment for lifestyle limiting claudication (LLC) that is due to infra-inguinal peripheral artery disease relies on either bypass, angioplasty, and/or stenting. Given the enthusiasm and shift toward more endovascular therapy for treatment of LLC, we sought to analyze whether octogenarians benefit from infra-inguinal interventions in the same manner as their younger counterparts. METHODS: We identified all patients admitted for elective treatment of LLC from the Nationwide Inpatient Sample from 2003 to 2012, who received open surgical or endovascular intervention for infra-inguinal peripheral arterial disease...

AIMS: Severe tricuspid regurgitation (TR) is common in patients with right-sided heart failure (HF) and causes substantial morbidity and mortality. Treatment options beyond medical therapy are limited for high-risk patients. Transcatheter edge-to-edge tricuspid valve (TV) repair showed procedural safety and short-term efficacy. Impact on mid-term outcome is unclear. This dual-centre observational study evaluates the mid-term safety, efficacy and clinical outcome after edge-to-edge TV repair for severe TR in patients with HF...

AIM: We now know that 20-40% of patients with a single ventricle will develop heart failure after the second decade post-Fontan surgery. However, we remain unable to risk-stratify the cohort to identify patients at highest risk of late failure and death. We conducted a systematic review of all reported late outcomes for patients with a Fontan circulation to identify predictors of late death. METHODS: We searched MEDLINE, Embase and PubMed with subject terms ("single ventricle", "Hypoplastic left heart syndrome", "congenital heart defects" or "Fontan procedure") AND ("heart failure", "post-operative complications", "death", "cause of death", "transplantation" or "follow-up studies") for relevant studies between January 1990 and December 2015...
