Increasing prevalence of obesity has led to a rise in the number of prospective obese heart and lung transplant recipients. The optimal management strategy of obese patients with end-stage heart and lung failure remains controversial. This review article discusses and provides a summary of the literature surrounding the impact of obesity on outcomes in heart and lung transplantation. Studies on transplant obesity demonstrate controversy in terms of morbidity and mortality outcomes and obesity pre-transplantation...

Domino heart transplant, wherein the explanted heart from the recipient of an en-bloc heart-lung is utilized for a second recipient, represents a unique surgical strategy for patients with end-stage heart failure. With a better understanding of the potential advantages and disadvantages of this procedure, its selective use in the current era can improve and maximize organ allocation in the United States. In this report, we reviewed the current status of domino heart transplantation.

Few studies have identified the psychosocial characteristics of those children and their families associated with future non-adherence to immunosuppressive medications following a heart or lung transplant. UNOS data and medical records information were used to test the association between patient and family psychosocial characteristics and medication adherence. Medication adherence outcomes were obtained using the physician assessments in the UNOS data and measured through patient-level standard deviation scores of immunosuppressive medication blood levels...

BACKGROUND: Research comparing the survival of children with familial dilated cardiomyopathy (FDCM) to that of children with idiopathic dilated cardiomyopathy (IDCM) has produced conflicting results. METHODS AND RESULTS: We analyzed data from children with FDCM or IDCM using the National Heart, Lung, and Blood Institute-funded Pediatric Cardiomyopathy Registry. Compared to children with IDCM (n=647), children with FDCM (n=223) were older (mean 6.2 versus 4.5 years, P<0...

Heritable pulmonary arterial hypertension (HPAH) is an autosomal dominantly inherited disease caused by mutations in the bone morphogenic protein receptor 2 gene and/or genes of its signalling pathway in about 85% of patients. We clinically and genetically analysed a HPAH family without mutations in previously described PAH genes. Clinical assessment included electrocardiogram, lung function, blood gas analysis, chest X-ray, laboratory testing, echocardiography and right heart catheterisation in case of suspected disease...

The process of pediatric solid organ transplantation (SOT) places new and increased stressors on patients and family members. Measures of family functioning may predict psychological and health outcomes for pediatric patients and their families, and provide opportunity for targeted intervention. This systematic review investigated parent and family functioning and factors associated with poorer functioning in the pediatric SOT population. Thirty-seven studies were identified and reviewed. Studies featured a range of organ populations (eg, heart, liver, kidney, lung, intestine) at various stages in the transplant process...

BACKGROUND: Cardiac allograft vasculopathy (CAV) remains an important cause of graft failure after heart transplantation (HT). Although many risk factors for CAV have been identified, there are no clinical prediction models that enable clinicians to determine each recipient's risk of CAV. METHODS: We studied a cohort of 14,328 heart transplant recipients whose data were reported to the International Society for Heart and Lung Transplantation Registry between 2000 and 2010...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) has been successfully used as a method for the interhospital transportation of critically ill patients. In South Korea, a well-established ECMO interhospital transport system is lacking due to limited resources. We developed a simplified ECMO transport system without mechanical ventilation for use by public emergency medical services. METHODS: Eighteen patients utilized our ECMO transport system from December 2011 to September 2015...

Transthoracic echocardiography (TTE) is a practical and widely used tool for risk stratification in pulmonary arterial hypertension (PAH). We hypothesized that right atrial (RA) reservoir function, represented by peak RA systolic strain, correlates with invasive hemodynamic measurements and clinical outcomes in PAH. Patients with group 1 PAH who had TTE within 6 months of index PAH clinic visit and right heart catheterization were included in this retrospective study. Peak RA strain in the 2D apical 4-chamber view was measured with speckle-tracking software...

Transplant recipients are at increased risk of tuberculosis (TB). We describe a case of pulmonary and vertebral multidrug-resistant TB (MDR-TB) in a kidney transplant patient who required neurosurgical intervention and unfortunately developed fatal nosocomial complications. Thirteen transplant recipients with MDR-TB were previously reported in the literature (1 hematopoietic cell transplant, 1 heart transplant, 1 lung transplant, 1 heart-lung ransplant, and 9 kidney transplant recipients). Extrapulmonary disease, severe treatment complications, and deaths were observed in patients who developed MDR-TB after transplantation...

BACKGROUND: Well-designed randomized controlled trials (RCTs) testing efficacy of post-transplant medication adherence enhancing interventions and clinical outcomes are scarce. METHODS: This randomized controlled trial enrolled adult heart, liver, and lung transplant recipients who were >1 year post-transplant and on tacrolimus twice daily (convenience sample) (visit 1). After a 3-month run-in period, patients were randomly assigned 1:1 to intervention group (IG) or control group (CG) (visit 2), followed by a 6-month intervention (visits 2-4) and a 6-month adherence follow-up period (visit 5)...

Amyloidosis is a heterogeneous group of diseases characterized by the deposition of amyloid. It is caused by extracellular deposition of insoluble fibrils with beta-pleated sheet configuration. The protein misfolding abnormalities result in amyloid fibrils and may manifest as primary, secondary, or familial amyloidosis. Amyloid deposition can occur in multiple organs (eg, heart, liver, kidney, skin, eyes, lungs, nervous system) resulting in a variety of clinical manifestations. Cardiac involvement can occur as part of a systemic disease or as a localized phenomenon...

REVIEW
Rogier van Gent, Herold J Metselaar, Jaap Kwekkeboom
Hyperimmunoglobulins are pharmaceutical formulations of human IgG which contain high titers of antibodies against specific viruses. They have been successfully used in solid organ transplantation (SOT) to prevent Cytomegalovirus (CMV) and Hepatitis B Virus (HBV) infection. The introduction of effective and cheaper antiviral drugs has resulted in decreasing usage of hyperimmunoglobulins in SOT. However, it may still be attractive to combine antiviral drug therapy with hyperimmunoglobulins after SOT, as there is some evidence that hyperimmunoglobulins, similar to high doses of intravenous immunoglobulins (IVIgs), might exert anti-inflammatory activity and thereby prevent immunological graft damage and improve graft and patient survival...

BACKGROUND: Barriers to access and long-term complications remain a challenge in transplantation. Further advancements may be achieved through research priority setting with patient engagement to strengthen its relevance. We evaluated research priority setting in solid organ transplantation and described stakeholder priorities. METHODS: Databases were searched to October 2016. We synthesized the findings descriptively. RESULTS: The 28 studies (n=2071 participants) addressed kidney (9 [32%]), heart (7 [25%]), liver (3 [11%]), lung (1 [4%]), pancreas (1 [4%]), and non-specified organ transplantation (7 [25%]) using consensus conferences, expert panel meetings, workshops, surveys, focus groups, interviews, and the Delphi technique...

Background There is a paucity of data on outcomes related to combined heart-lung transplantations (HLTs). Our objective was to identify variables associated with mortality and rejection in HLT. Methods The United Network for Organ Sharing database was reviewed for HLT performed between 1993 and 2008. Long-term survivors (survival > 5 years) were compared with short-term survivors (survival < 5 years). Factors associated with rejection were examined. Risk-adjusted multivariable Cox's proportional hazards regression analysis was performed to examine variables associated with mortality and rejection...

Dysfunction of the systemic right ventricle is common after the atrial switch procedure for transposition of the great arteries. Cardiac transplantation remains the only long-term solution in terminal systemic right ventricular (RV) failure, but concomitant pulmonary hypertension (PHT) may preclude it. The increasing number of such patients, together with the concerns related to combined heart-lung transplantation (HLTx), urge us to consider other therapeutic options.

OBJECTIVE: Although video-assisted thoracic surgery (VATS) lobectomy has become a standard approach for early-stage 1 lung cancer, concerns exist regarding potential damage to the heart or bypass grafts when VATS is performed after cardiac surgery via median sternotomy. We could find only case reports regarding VATS lobectomy after sternotomy for cardiac surgery. Therefore, we reviewed our series of patients who underwent VATS anatomic resections after sternotomy for cardiac surgery. METHODS: Between 1996 and 2010, there were 87 patients who underwent 88 pulmonary resections after sternotomy for coronary artery bypass grafting (64), valve replacement or repair (12), coronary artery bypass graft and valve replacement (6), and transplant (5)...
