Change in Caregiver Health-Related Quality of Life From Before to Early After Surgery: SUSTAIN-IT Study.

Background: Information about health-related quality of life (HRQOL) among caregivers of older patients with heart failure who receive heart transplantation (HT) and mechanical circulatory support (MCS) is sparse. We describe differences and factors associated with change in HRQOL before and early post-surgery among caregivers of older heart failure patients who underwent 3 surgical therapies: HT with pretransplant MCS (HT MCS), HT without pretransplant MCS (HT non-MCS), and long-term MCS.

Methods: Caregivers of older patients (60-80 years) from 13 US sites completed the EQ-5D-3 L visual analog scale (0 [worst]-100 [best] imaginable health state) and dimensions before and 3 and 6 months post-surgery.

Caregiver burden before heart transplantation and long-term mechanical circulatory support: Findings from the sustaining quality of life of the aged: Transplant or mechanical support (SUSTAIN-IT) study.

Background: Caregiving for heart failure (HF) patients is burdensome. We examined differences in caregiver burden for 3 groups of older advanced HF patients: (1) supported with mechanical circulatory support (MCS) before heart transplantation (HT MCS), (2) awaiting transplant without MCS (HT non-MCS), and (3) prior to long-term MCS and factors associated with burden.

Method: From October 1, 2015 to December 31, 2018, we enrolled 276 caregivers for HF patients from 13 U.

Health-Related Quality of Life in Older Patients With Heart Failure From Before to Early After Advanced Surgical Therapies: Findings From the SUSTAIN-IT Study.

Background: Restoring health-related quality of life (HRQOL) is a therapeutic goal for older patients with advanced heart failure. We aimed to describe change in HRQOL in older patients (60-80 years) awaiting heart transplantation (HT) with or without pretransplant mechanical circulatory support (MCS) or scheduled for long-term MCS, if ineligible for HT, from before to 6 months after these surgeries and identify factors associated with change.

Methods: Patients from 13 US sites completed the EuroQol 5-dimension 3L questionnaire and Kansas City Cardiomyopathy Questionnaire-12 at baseline and 3 and 6 months after HT or long-term MCS.

Baseline Quality-of-Life of Caregivers of Patients With Heart Failure Prior to Advanced Therapies: Findings From the Sustaining Quality of Life of the Aged: Transplant or Mechanical Support (SUSTAIN-IT) Study.

Background: We compared health-related quality of life (HRQOL), depressive symptoms, anxiety, and burden in caregivers of older patients with heart failure based on the intended therapy goal of the patient: awaiting heart transplantation (HT) with or without mechanical circulatory support (MCS) or prior to long-term MCS; and we identified factors associated with HRQOL.

Methods: Caregivers (n = 281) recruited from 13 HT and MCS programs in the United States completed measures of HRQOL (EQ-5D-3L), depressive symptoms (PHQ-8), anxiety (STAI-state), and burden (Oberst Caregiving Burden Scale). Analyses included ANOVA, Kruskal-Wallis tests, χ tests, and linear regression.

Health-Related Quality of Life in Older Patients With Advanced Heart Failure: Findings From the SUSTAIN-IT Study.

Background There is a paucity of research describing health-related quality of life (HRQOL) in older adults considered for advanced heart failure surgical therapies. Using data from our SUSTAIN-IT (Sustaining Quality of Life of the Aged: Heart Transplant or Mechanical Support) study, we aimed to compare HRQOL among 3 groups of older (60-80 years) patients with heart failure before heart transplantation (HT) or long-term mechanical circulatory support (MCS) and identify factors associated with HRQOL: (1) HT candidates with MCS, (2) HT candidates without MCS, or (3) candidates ineligible for HT and scheduled for long-term MCS. Methods and Results Patients from 13 US sites completed assessments, including self-reported measures of HRQOL (EuroQol-5 Dimension Questionnaire, Kansas City Cardiomyopathy Questionnaire-12), depressive symptoms (Personal Health Questionnaire-8), anxiety (State-Trait Anxiety Inventory-state form), cognitive status (Montreal Cognitive Assessment), and performance-based measures (6-minute walk test and 5-m gait speed).

Management of Pulmonary Mucormycosis After Orthotopic Heart Transplant: A Case Series.

Invasive pulmonary mucormycosis is a potentially fatal infection that can occur in immunosuppressed patients such as those who have undergone orthotopic heart transplant (OHT). High-dose intravenous antifungal agents, including amphotericin B, are generally accepted as the first-line medical treatment, with prompt surgical resection of lesions if feasible. The body of evidence guiding treatment decisions, however, is sparse, particularly regarding adjustment of immunosuppression during acute infection and long-term recovery.

Outcomes of pre- heart transplantation desensitization in a series of highly sensitized patients bridged with left ventricular assist devices.

Desensitization therapy for heart transplantation (HT) candidates can shorten transplant wait times and broaden the donor pool. Specific evidence-based recommendations on both protocols and indications are lacking. We retrospectively assessed left ventricular assist devices-bridged candidates who received pre-HT desensitization therapy.

Impact of pre-existing heart failure on 60-day outcomes in patients hospitalized with COVID-19.

Background: In the coronavirus disease 2019 (COVID-19) global pandemic, patients with cardiovascular disease represent a vulnerable population with higher risk for contracting COVID-19 and worse prognosis with higher case fatality rates. However, the relationship between COVID-19 and heart failure (HF) is unclear, specifically whether HF is an independent risk factor for severe infection or if other accompanying comorbidities are responsible for the increased risk.

Methods: This is a retrospective analysis of 1331 adult patients diagnosed with COVID-19 infection between March and June 2020 admitted at Rush University System for Health (RUSH) in metropolitan Chicago, Illinois, USA.

Outcomes Following Left Ventricular Assist Device Exchange: Focus on the Impacts of Device Infection.

Hemodynamic support with continuous-flow left ventricular assist device (CF-LVAD) therapy has proven a reliable treatment for advanced heart failure. Although modern LVADs are highly durable, device failure and infection can be resolved with surgical exchange of pump components. In this study, we investigated the incidence and outcomes of LVAD exchange with the HeartMate II and HeartWare HVAD.

Cost-Effectiveness of a Small Intrapericardial Centrifugal Left Ventricular Assist Device.

There is limited data on the cost-effectiveness of continuous-flow left ventricular assist devices (LVAD) in the United States particularly for the bridge-to-transplant indication. Our objective is to study the cost-effectiveness of a small intrapericardial centrifugal LVAD compared with medical management (MM) and subsequent heart transplantation using the respective clinical trial data. We developed a Markov economic framework.

A case series of patients with left ventricular assist devices and concomitant mechanical heart valves.

Mechanical heart valves left in situ at the time of left ventricular assist device (LVAD) implantation are thought to potentially increase the risk of thromboembolism. Recommendations exist to replace dysfunctional mechanical mitral valves and any mechanical aortic valves at the time of LVAD implantation. Due to potential increases in cardiopulmonary bypass time and associated comorbidities with valve replacement, leaving a functional mechanical valve in place at LVAD implantation has been suggested to be a safe option.

Venoarterial extracorporeal membrane oxygenation use in staged combined heart-kidney transplant.

Outside of heart and lung transplantation, only few cases have been reported describing venoarterial extracorporeal membrane oxygenation (VA-ECMO) use in solid organ transplantation. We present a case of a staged combined heart-kidney transplant in which VA-ECMO was utilized after a complicated orthotopic heart transplantation to successfully complete the subsequent renal transplantation.

Regional Variation in the Association of Poverty and Heart Failure Mortality in the 3135 Counties of the United States.

Background There is significant geographical variation in heart failure (HF) mortality across the United States. County socioeconomic factors that influence these outcomes are unknown. We studied the association between county socioeconomic factors and HF mortality and compared it with coronary heart disease (CHD) mortality.

A Fully Magnetically Levitated Left Ventricular Assist Device - Final Report.

Background: In two interim analyses of this trial, patients with advanced heart failure who were treated with a fully magnetically levitated centrifugal-flow left ventricular assist device were less likely to have pump thrombosis or nondisabling stroke than were patients treated with a mechanical-bearing axial-flow left ventricular assist device.

Methods: We randomly assigned patients with advanced heart failure to receive either the centrifugal-flow pump or the axial-flow pump irrespective of the intended goal of use (bridge to transplantation or destination therapy). The composite primary end point was survival at 2 years free of disabling stroke or reoperation to replace or remove a malfunctioning device.

Multicenter experience with durable biventricular assist devices.

Background: Severe right ventricular failure necessitating a right ventricular assist device (RVAD) complicates 6% to 11% of left ventricular assist device (LVAD) implants. Patient outcomes for those receiving durable continuous-flow VADs in a biventricular configuration (i.e.

Two-Year Outcomes with a Magnetically Levitated Cardiac Pump in Heart Failure.

Background: In an early analysis of this trial, use of a magnetically levitated centrifugal continuous-flow circulatory pump was found to improve clinical outcomes, as compared with a mechanical-bearing axial continuous-flow pump, at 6 months in patients with advanced heart failure.

Methods: In a randomized noninferiority and superiority trial, we compared the centrifugal-flow pump with the axial-flow pump in patients with advanced heart failure, irrespective of the intended goal of support (bridge to transplantation or destination therapy). The composite primary end point was survival at 2 years free of disabling stroke (with disabling stroke indicated by a modified Rankin score of >3; scores range from 0 to 6, with higher scores indicating more severe disability) or survival free of reoperation to replace or remove a malfunctioning device.

Extracorporeal membrane oxygenation support and post-heart transplant outcomes among United States adults.

Background: Patients supported with extracorporeal membrane oxygenation (ECMO) are given priority listing status for heart transplant (HT). Data on post-HT outcomes for adults with ECMO support at the time of HT are limited.

Methods: We analyzed data from the United Network for Organ Registry (UNOS) registry for 157 ECMO-supported adults (age ≥ 18 years) undergoing HT after January 1, 2000.

Gene expression profiling to study racial differences after heart transplantation.

Background: The basis for increased mortality after heart transplantation in African Americans and other non-Caucasian racial groups is poorly defined. We hypothesized that increased risk of adverse events is driven by biologic factors. To test this hypothesis in the Invasive Monitoring Attenuation through Gene Expression (IMAGE) study, we determined whether the event rate of the primary outcome of acute rejection, graft dysfunction, death, or retransplantation varied by race as a function of calcineurin inhibitor (CNI) levels and gene expression profile (GEP) scores.

An examination of survival by sex and race in the HeartWare Ventricular Assist Device for the Treatment of Advanced Heart Failure (ADVANCE) Bridge to Transplant (BTT) and continued access protocol trials.

Background: The Ventricular Assist Device for the Treatment of Advanced Heart Failure (ADVANCE) Bridge to Transplant (BTT) trial was a multicenter, prospective trial of the HeartWare Ventricular Assist Device (HVAD). The performance of the HVAD in various demographic sub-groups was evaluated.

Methods: Baseline characteristics, adverse events, and survival were compared for men vs.

Impact of identification and treatment of depression in heart transplant patients.

Background. The effects of clinical depression after orthotopic heart transplantation (OHT) are relatively unknown. The purpose of this study was to evaluate the impact of depression on outcomes after OHT.

Predictors of hospital length of stay after implantation of a left ventricular assist device: an analysis of the INTERMACS registry.

Background: Few studies have reported on hospital length of stay (LOS) after left ventricular assist device (LVAD) implantation. The purpose of this study was to determine pre- and peri-operative predictors of hospital LOS after LVAD implantation.

Methods: We analyzed adult primary continuous-flow LVAD patients implanted between June 23, 2006 and December 31, 2010 at 105 institutions from the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS).

Utility of gene expression profiling score variability to predict clinical events in heart transplant recipients.

Background: Gene expression profiling test scores have primarily been used to identify heart transplant recipients who have a low probability of rejection at the time of surveillance testing. We hypothesized that the variability of gene expression profiling test scores within a patient may predict risk of future events of allograft dysfunction or death.

Method: Patients from the IMAGE study with rejection surveillance gene expression profiling tests performed at 1- to 6-month intervals were selected for this cohort study.
