Left ventricular assist device exchanges: A safe and effective strategy in the era of limited organ availability.

Background: Ongoing donor-organ shortage has limited transplantation making LVADs an effective alternative therapy for patients with end-stage heart failure. When LVAD-associated complications arise device exchange is a feasible and safe alternative. This study addresses the factors that impact survival post-LVAD exchange.

Temporary Mechanical Support in Cardiogenic Shock Secondary to Heart Failure: An Evolving Paradigm.

Cardiogenic shock can be defined as a state of circulatory collapse resulting in hypoperfusion and end-organ dysfunction. It carries a large burden of mortality, but management strategies are driven by expert consensus rather than adequately powered randomized clinical trials. The goal of this review is to highlight the differences in presentation and outcomes in cardiogenic shock depending on the etiology, such as acute myocardial infarction (AMI) versus acute-on-chronic heart failure (HF), gender-based differences in treatment strategies and outcomes and the need for more precise risk stratification and modeling to improve the efficiency of treatment delivery in a personalized fashion.

Outcomes of Left Atrial Appendage Occlusion Treatment With Amulet After Unsuccessful Watchman FLX Device: A Multicenter Observational Study.

Introduction: Watchman FLX (W-FLX) is the most widely used left atrial appendage occlusion (LAAO) device to prevent atrial fibrillation (AF) related strokes in the United States. However, successful LAAO with W-FLX can be challenging in patients with complex left atrial appendage (LAA) anatomies. This analysis aimed to assess the procedural success rates of LAA occlusion (immediate and short-term outcomes) using the Amulet device, in patients with prior failed LAAO with W-FLX device.

Risk Prediction of Post-Transplant Lymphoproliferative Disease in Heart Transplant Patients.

Post-transplant lymphoproliferative disease (PTLD) represents the second most frequent malignancy in cardiac allograft recipients and constitutes up to 10% of de novo cancers. This study attempts to determine risk factors in adult heart transplant patients to develop a risk prediction model using the Scientific Registry of Transplant Recipients database and the lasso regression model. Data on 55,150 adult heart transplant patients (1987-2021) were extracted.

Comparing mental health and substance use disorders in patients receiving durable VADs versus transplants: A TriNetX database analysis.

Ventricular assist device (VAD) and cardiac transplant patients experience significant strain on their physical and mental wellbeing postoperatively. Mental health and substance use disorders (MHDs and SUDs) have substantial effects on the quality of life and compliance of transplant and VAD patients. In this study, we compare and characterize MHDs and SUDs between VAD and cardiac allograft patients and transplant list patients with and without VADs.

Use of Intravascular Micro-Axial Left Ventricular Assist Devices as a Bridging Strategy for Cardiogenic Shock: Mid-Term Outcomes.

: Patients in cardiogenic shock (CS) may be successfully bridged using intravascular micro-axial left ventricular assist devices (M-LVADs) for recovery or determination of definitive therapy. : One hundred and seven CS patients implanted with M-LVADs from January 2020 to May 2024 were divided into four groups; group-1: 34 patients (transplant); group-2: 25 patients (LVAD); group-3: 42 patients (postcardiotomy CS (PCCS)); group-4: 6 patients (decision/recovery but excluded from analysis). Multivariable logistic regression and Multivariable Coxregression models identified predictors of early -hospital and late mortality, and Odds ratios (ORs) and hazard ratios (HRs) with < 0.

The Long-Term Survival of LVAD Patients-A TriNetX Database Analysis.

Donor shortage limits the utilization of heart transplantation, making it available for only a fraction of the patients on the transplant waiting list. Therefore, continuous-flow left ventricular assist devices (CF-LVADs) have evolved as a standard of care for end-stage heart failure. It is imperative therefore to investigate long-term survival in this population.

Mental Health and Substance Use Disorders in Transplant Waitlist, VAD, and Heart Transplant Patients: A TriNetX Database Analysis.

: Mental health and substance use disorders (MHDs and SUDs) affect cardiac allograft and VAD recipients and impact their quality of life and compliance. Limited research currently exists on MHDs and SUDs in this population. : This study compares the incidence of MHDs and SUDs in the transplant list, VAD, and post-transplant patients with that in heart failure patients.

Propensity matched post-transplant survival in durable CF-axial pump BTT patients with and without diabetes: A UNOS database analysis.

Diabetes and post-transplant survival have been linked. However, the impact on post-transplant survival of patients supported on Continuous Flow (CF) axial left ventricular assist devices (LVAD) as a bridge to transplant (BTT) with diabetes has not been widely studied. This study attempts to assess the impact of diabetes type II (DM type II) as a comorbidity influencing survival patterns in the post-cardiac transplant population supported on LVADs and to test if the presence of a pre- transplant durable LVAD acts as an independent risk factor in long-term post-transplant survival.

Outcomes in Heart Transplant Recipients by Bridge to Transplant Strategy When Using the SherpaPak Cardiac Transport System.

The last several years have seen a rise in use of mechanical circulatory support (MCS) to bridge heart transplant recipients. A controlled hypothermic organ preservation system, the SherpaPak Cardiac Transport System (SCTS), was introduced in 2018 and has grown in utilization with reports of improved posttransplant outcomes. The Global Utilization And Registry Database for Improved heArt preservatioN (GUARDIAN)-Heart registry is an international, multicenter registry assessing outcomes after transplant using the SCTS.

Enhanced Left Ventricular Recovery in Treatment of Mitral Regurgitation With Severe Left Ventricular Dysfunction.

A 73-year-old male patient presented with shortness of breath at rest resulting from new-onset severe primary mitral regurgitation with a flail posterior leaflet, left ventricular dysfunction, and cardiogenic shock. After initial stabilization in the intensive care unit, multiple treatment options were considered for this patient, all associated with significant mortality. Ultimately, operative mitral valve repair with Impella 5.

The emerging role of cardiac contractility modulation in heart failure treatment.

Purpose Of Review: Heart failure often progresses despite optimal medical and device therapies, and advanced mechanical circulatory support has limited availability and substantial associated morbidity. Cardiac contractility modulation (CCM) provides nonexcitatory stimulation to ventricular myocardium which increases cardiac contractility without increasing oxygen demand. This review describes the emerging role of CCM in heart failure treatment.

Novel strategy for improved outcomes of extra-corporeal membrane oxygenation as a treatment for refractory post cardiotomy cardiogenic shock in the current era: a refreshing new perspective.

Objectives: Post-cardiotomy cardiogenic shock is an infrequent but important cause of death following cardiac surgery. Extra-corporeal membrane oxygenation offers the opportunity for temporary cardiovascular support and myocardial rest, with a view to recovery. We examine our results with our recently-implemented management algorithm.

Prevention and Early Recognition of Complications During Catheter Ablation by Intracardiac Echocardiography.

The effective diagnosis and management of procedural complications remains an important challenge for electrophysiology operators. Intracardiac echocardiography provides a real-time imaging modality with spectral and color Doppler capabilities that integrates directly with electroanatomic mapping systems. It provides detailed characterization of anatomic variants, which allows the operator to optimize the ablation strategy to the individual thereby avoiding the inherent risk of excessive or ineffective lesions.

Utilization of extracorporeal membrane oxygenation in DCD and DBD lung transplants: a 2-year single-center experience.

Donation after circulatory death (DCD) has the potential to expand the lung donor pool. We aimed to assess whether DCD affected the need for perioperative extracorporeal membrane oxygenation (ECMO) and perioperative outcomes in lung transplantation (LTx) as compared to donation after brain death (DBD). All consecutive LTxs performed between April 2017 and March 2019 at our tertiary center were analyzed.

Use of oxygenator with short-term ventricular assist devices.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) serves as a conventional short-term mechanical circulatory assist to support heart and lung functions. The short-term ventricular assist devices (ST-VAD) can, on the contrary, offer only circulatory support. A combination of VAD and oxygenator (Oxy-VAD) could help overcome this potential disadvantage.
