A gift of life, not immortality: Evaluation of a strategy of heart transplant listing in the older patient with advanced heart failure.

Patients 65 years of age or older represent the fastest-growing demographic group added to the U.S. heart transplant (HT) list.

Donor Selection for Heart Transplantation in 2024.

The number of candidates on the waiting list for heart transplantation (HT) continues to far outweigh the number of available organs, and the donor heart nonuse rate in the United States remains significantly higher than that of other regions such as Europe. Although predicting outcomes in HT remains challenging, our overall understanding of the factors that play a role in post-HT outcomes continues to grow. We observe that many donor risk factors that are deemed "high-risk" do not necessarily always adversely affect post-HT outcomes, but are in fact nuanced and interact with other donor and recipient risk factors.

Advancing patient-centered metrics for heart transplantation: The role of days alive and outside the hospital.

Background: Heart transplantation (HT) survival and waitlist times are established outcome metrics. Patient-centered HT outcomes are insufficiently characterized. This study evaluates the role of days alive and outside the hospital (DAOH) as a candidate patient-centered HT performance measure.

Hemodynamic Effects and Clinical Outcomes of Left Atrial Veno-Arterial Extracorporeal Membrane Oxygenation (LAVA-ECMO) in Cardiogenic Shock.

Left atrial veno-arterial extracorporeal membrane oxygenation (LAVA-ECMO) in cardiogenic shock (CS) is a novel mechanical cardiocirculatory support strategy that provides robust cardiocirculatory support and simultaneous left and right atrial venting by way of a multifenestrated transeptal catheter. We performed a single-center retrospective analysis of all patients aged ≥18 years with CS who underwent LAVA-ECMO at a quaternary care institution from 2018 to 2023. Clinical outcomes and prehemodynamics and posthemodynamics were evaluated.

Defining optimal left ventricular assist device short-term outcomes may provide insight into programmatic quality assessment.

Background: Patients have substantial variability in perioperative outcomes after left ventricular assist device (LVAD) implant. A perioperative multidimensional tool integrating mortality, adverse events (AEs), and patient-reported outcomes to assist in quality improvement initiatives is needed.

Methods: Patients undergoing HeartMate 3 LVAD implant (January 1, 2017 to January 31, 2024) in the Society of Thoracic Surgeons' Intermacs registry were studied.

Feasibility and Outcomes of a Cardiovascular Medicine Inclusive Extracorporeal Membrane Oxygenation (ECMO) Service.

Background: There has been a significant increase in the utilization of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in recent years. Cardiothoracic surgery teams have historically led VA-ECMO care teams, with little data available on alternative care models.

Methods: We performed a retrospective review of a cardiovascular medicine inclusive VA-ECMO service, analyzing patients treated with peripheral VA-ECMO at a large quaternary care center from 2018 to 2022.

Aortic insufficiency in the patient on contemporary durable left ventricular assist device support: A state-of-the-art review on preoperative and postoperative assessment and management.

The development of aortic insufficiency (AI) during HeartMate 3 durable left ventricular assist device (dLVAD) support can lead to ineffective pump output and recurrent heart failure symptoms. Progression of AI often comingles with the occurrence of other hemodynamic-related events encountered during LVAD support, including right heart failure, arrhythmias, and cardiorenal syndrome. While data on AI burdens and clinical impact are still insufficient in patients on HeartMate 3 support, moderate or worse AI occurs in approximately 8% of patients by 1 year and studies suggest AI continues to progress over time and is associated with increased frequency of right heart failure.

Extrinsic outflow graft obstruction of the HeartMate 3 LVAD: A state-of-the-art review.

While notable improvements in survival, the incidence of hemocompatibility-related adverse events, hospitalizations, and cost have been demonstrated with the only commercially available durable left ventricular assist device, a category of pump malfunctions characterized by outflow graft obstruction has been noted with broader use and clinical follow-up of recipients of this technology. Of particular concern is the accumulation of acellular biodebris between the outflow graft and bend relief covering the outflow graft at its origin with the pump (which we term extrinsic outflow graft obstruction at the bend relief). This process tends to be insidious, occurs late in the postoperative course, can be challenging to diagnose, and can result in significant morbidity and mortality.

An ISHLT consensus statement on strategies to prevent and manage hemocompatibility related adverse events in patients with a durable, continuous-flow ventricular assist device.

Life expectancy of patients with a durable, continuous-flow left ventricular assist device (CF-LVAD) continues to increase. Despite significant improvements in the delivery of care for patients with these devices, hemocompatability-related adverse events (HRAEs) are still a concern and contribute to significant morbility and mortality when they occur. As such, dissemination of current best evidence and practices is of critical importance.

The International Society for Heart and Lung Transplantation (ISHLT): 2024 infection definitions for durable and acute mechanical circulatory support devices.

Infections remain a significant concern in patients receiving mechanical circulatory support (MCS), encompassing both durable and acute devices. This consensus manuscript provides updated definitions for infections associated with durable MCS devices and new definitions for infections in acute MCS, integrating a comprehensive review of existing literature and collaborative discussions among multidisciplinary specialists. By establishing consensus definitions, we seek to enhance clinical care, facilitate consistent reporting in research studies, and ultimately improve outcomes for patients receiving MCS.

Use of percutaneous mechanical circulatory support for right ventricular failure.

Background: Utilization of right ventricular mechanical circulatory support (RV-MCS) devices has been limited by a lack of recognition of RV failure as well as a lack of availability and experience with RV-MCS.

Aims: We report a single-center experience with the use of percutaneous RV-MCS and report predictors of adverse outcomes.

Methods: This was a single-center retrospective cohort study.

Early vs. delayed mechanical circulatory support in patients with acute myocardial infarction and cardiogenic shock.

Aims: Despite increased temporary mechanical circulatory support (tMCS) utilization for acute myocardial infarction complicated by cardiogenic shock (AMI-CS), data regarding efficacy and optimal timing for tMCS support are limited. This study aimed to describe outcomes based on tMCS timing in AMI-CS and to identify predictors of 30-day mortality and readmission.

Methods And Results: Patients with AMI-CS identified in the National Readmissions Database were grouped according to the use of tMCS and early (<24 h) vs.
