Tailored Therapy in Cardiogenic Shock: Case-Based Management Choices.

Cardiogenic shock (CS) is a complex, multisystem disorder precipitated by hypoperfusion from cardiac dysfunction. Our current approach to defining and treating CS encompasses all patients under 1 umbrella regardless of phenotype. This has created challenges for clinical trials and patient care owing to the heterogeneity of the patient population with CS.

Sexual Quality of Life in Left Ventricular Assist Device Patients and Their Partners.

Background: Living with a left ventricular assist device (LVAD) comes with potentially burdensome aspects posed by, for example, battery packs and device drivelines. We aim to describe the impact of living with a durable LVAD on sexual quality of life (QOL), depression, and anxiety in patients and their partners.

Methods And Results: In this single-center, prospective, observational study, patients ≥4 months after LVAD implantation and their partners completed the Sexual Activities in Left Ventricular Assist Device Patients or Partners questionnaire to assess their sexual QOL, the 8-item Patient Health Questionnaire (PHQ-8) to assess symptoms of depression and the 7-item Generalized Anxiety Disorder (GAD-7) to assess symptoms of anxiety.

The impact of active cytomegalovirus infection on donor-derived cell-free DNA testing in heart transplant recipients.

Background: Little is known about the relationship between cytomegalovirus (CMV) infections and donor-derived cell-free DNA (dd-cfDNA) in heart transplant recipients.

Methods: In our study, CMV and dd-cfDNA results were prospectively collected on single-organ heart transplant recipients. If the CMV study was positive, a CMV study with dd-cfDNA was repeated 1-3 months later.

Does temporary mechanical circulatory support with Impella 5.5 induce de novo human leukocyte antigen antibodies production in heart transplantation candidates?

Background: Little is known about de novo human luekocyte antigen (HLA) antibody development with Impella 5.5 temporary mechanical circulatory assist support and downstream effects following heart transplantation in the new heart allocation system.

Methods: Thirteen Impella and 17 control patients without device support were prospectively enrolled between December 2020 and June 2022.

Three-year outcomes of de novo tacrolimus extended-release tablets (LCPT) compared to twice-daily tacrolimus in adult heart transplantation.

Background: Extended-release tacrolimus for prophylaxis of allograft rejection in heart transplant (HT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release (IR-) tacrolimus. We compared long-term efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients.

Early elevated donor-derived cell-free DNA levels in heart transplant recipients following precision-controlled cardiac transport system or ice-cooled organ transport.

Background: Recent innovations in temperature-controlled cardiac transportation allow for static hypothermic preservation of transplant organs during transportation. We assessed differences in donor-derived cell-free DNA (dd-cfDNA) using the SherpaPak cardiac transport system (SCTS) and traditional ice transportation.

Methods: Single-organ heart transplant recipients between January 2020 and January 2022 were included if they had dd-cfDNA measures ≤6 weeks post-transplant along with the baseline biopsy at 6 weeks as part of the surveillance protocol and no biopsy-confirmed rejection ≤90 days.

Predictors of 5-Year Mortality in Patients Managed With a Magnetically Levitated Left Ventricular Assist Device.

Background: In advanced heart failure patients implanted with a fully magnetically levitated HeartMate 3 (HM3, Abbott) left ventricular assist device (LVAD), it is unknown how preimplant factors and postimplant index hospitalization events influence 5-year mortality in those able to be discharged.

Objectives: The goal was to identify risk predictors of mortality through 5 years among HM3 LVAD recipients conditional on discharge from index hospitalization in the MOMENTUM 3 pivotal trial.

Methods: This analysis evaluated 485 of 515 (94%) patients discharged after implantation of the HM3 LVAD.

Challenges with the current United Network for Organ Sharing heart allocation system.

Purpose Of Review: The revised United States heart organ allocation system was launched in October 2018. In this review, we summarize this United Network for Organ Sharing (UNOS) policy and describe intended and unintended consequences.

Recent Findings: Although early studies published after the change suggested postheart transplant survival declined at 6 months and 1 year, recent publications with longer follow-up time have confirmed comparable posttransplant survival in adjusted models and several patient cohorts.

Safety and efficacy of ProtekDuo right ventricular assist device: A systemic review.

Background: Right ventricular failure is associated with increased morbidity and mortality. The ProtekDuo (Livanova, Uk) is a dual-lumen cannula that allows for percutaneous right ventricular support and may be connected to a centrifugal blood pump such as the TandemHeart or LifeSparc (Livanova, UK). This systematic review aims to evaluate the safety and efficacy of ProtekDuo right ventricular support and evaluate potential clinical variables that can influence outcomes.

Addressing sex-based disparities in solid organ transplantation in the United States - a conference report.

Solid organ transplantation provides the best treatment for end-stage organ failure, but significant sex-based disparities in transplant access exist. On June 25, 2021, a virtual multidisciplinary conference was convened to address sex-based disparities in transplantation. Common themes contributing to sex-based disparities were noted across kidney, liver, heart, and lung transplantation, specifically the existence of barriers to referral and wait listing for women, the pitfalls of using serum creatinine, the issue of donor/recipient size mismatch, approaches to frailty and a higher prevalence of allosensitization among women.

Donor heart selection: Evidence-based guidelines for providers.

The proposed donor heart selection guidelines provide evidence-based and expert-consensus recommendations for the selection of donor hearts following brain death. These recommendations were compiled by an international panel of experts based on an extensive literature review.

Heart transplant Recipients' perspectives on invasive versus Non-invasive graft failure surveillance Methods.

Background: Heart transplant recipients must regularly be assessed for graft rejection; however, endomyocardial biopsy (EMB), can be stressful, painful, and inconvenient. AlloMap® is the only commercially available non-invasive test for graft rejection. Current guidelines include AlloMap® testing in low-risk patients OBJECTIVES: To examine the patients' perspective, this study compared patients' experiences of AlloMap® and EMB surveillance at our center.

Special Considerations in the Care of Women With Advanced Heart Failure.

Advanced heart failure (AHF) is associated with increased morbidity and mortality, and greater healthcare utilization. Recognition requires a thorough clinical assessment and appropriate risk stratification. There are persisting inequities in the allocation of AHF therapies.

Concurrent valvular procedures during left ventricular assist device implantation and outcomes: A comprehensive analysis of the Multicenter Study of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy With HeartMate 3 trial portfolio.

Background: Correction of valvular disease is often undertaken during left ventricular assist device (LVAD) implantation with uncertain benefit. We analyzed clinical outcomes with HeartMate 3 (HM3; Abbott) LVAD implantation in those with various concurrent valve procedures (HM3+VP) with those with an isolated LVAD implant (HM3 alone).

Methods: The study included 2200 patients with HM3 implanted within the Multicenter Study of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy with HeartMate 3 (MOMENTUM 3) trial portfolio who underwent 820 concurrent procedures among which 466 (21.

The "Right" Definition for Post-Left Ventricular Assist Device Right Heart Failure: The More We Learn, the Less We Know.

Right heart failure is a major cause of morbidity and mortality following left ventricular assist device implantation. Over the past few decades, the definition proposed by the Interagency Registry of Mechanical Circulatory Support and Society of Thoracic Surgeons has continually evolved to better identify this complex pathology. We propose that the latest definition proposed by the Mechanical Circulatory Support Academic Research Consortium in 2020 will increase our recognition and understanding of this complex disease phenomenon.

Observed elevated donor-derived cell free DNA in orthotopic heart transplant recipients without clinical evidence of rejection.

Donor-derived cell free DNA (dd-cfDNA) has rapidly become part of rejection surveillance following orthotopic heart transplantation. However, some patients show elevated dd-cfDNA without clinical evidence of rejection. With the aim to provide a clinical description of this subpopulation, we retrospectively analyzed 35 cardiac transplant recipients at our center who experienced elevated (≥.

Urinary Cell-Cycle Arrest Biomarkers as Early Predictors of Acute Kidney Injury After Ventricular Assist Device Implantation or Cardiac Transplantation.

Objectives: Acute kidney injury (AKI) remains a leading source of morbidity and mortality after cardiothoracic surgery. Insulin-like growth factor-binding protein 7 (IGFBP7), and tissue inhibitor of metalloproteinases-2 (TIMP-2), are novel early-phase renal biomarkers that have been validated as sensitive predictors of AKI. Here the authors studied the efficacy of these biomarkers for predicting AKI after left ventricular assist device (LVAD) implantation and cardiac transplantation.

De novo tacrolimus extended-release tablets (LCPT) versus twice-daily tacrolimus in adult heart transplantation: Results of a single-center non-inferiority matched control trial.

Extended-release tacrolimus for prophylaxis of allograft rejection in orthotopic heart transplant (OHT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release tacrolimus (IR-tacrolimus). We compared the efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients.

Impact of risk-stratified mycophenolate dosing in heart transplantation.

Mycophenolate mofetil (MMF), the prodrug of mycophenolic acid, is a highly effective immunosuppressive agent in heart transplant therapy. While the FDA approved dose is 1500 mg twice daily, dosing is often reduced due to dose-dependent adverse effects. However, empiric MMF dose reductions may lead to sub-therapeutic dosing and impair clinical outcomes.
