Galectin-3 as a Prognostic Biomarker of Left Ventricular Assist Device Implantation Outcomes.

We assessed the prognostic potential of Galectin-3 in a sample of 159 heart failure patients who received a left ventricular assist device (LVAD) implant from 2012 to 2020. Clinical outcomes included hemodynamic data, right heart failure (RHF), hemocompatibility-related adverse events (HRAEs), and mortality. Galectin-3 was compounded into Michigan-RVF and EUROMACS-RHF risk scores and compared to the noncompounded risk scores.

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.

PREDICT HF: Risk stratification in advanced heart failure using novel hemodynamic parameters.

Background: Invasive hemodynamics are fundamental in assessing patients with advanced heart failure (HF). Several novel hemodynamic parameters have been studied; however, the relative prognostic potential remains ill-defined.

Hypothesis: Advanced hemodynamic parameters provide additional prognostication beyond the standard hemodynamic assessment.

New-Onset Neurosarcoidosis Following Heart Transplant for Cardiac Sarcoidosis.

A 63-year-old woman who underwent heart transplantation for cardiac sarcoidosis developed new headache and vision changes. Extensive workup resulted in a diagnosis of neurosarcoidosis treated with pulse dose steroids and infliximab. Recurrence of sarcoidosis after transplantation for isolated cardiac sarcoidosis occurs, but optimal surveillance methods remain unknown.

Advanced hemodynamics for prognostication in heart failure: the pursuit of the patient-specific tipping point.

Background: Objective tools to define the optimal time for referral for advanced therapies and to help guide escalation and de-escalation of support can improve management decisions and outcomes for patients with advanced heart failure. The current parameters have variable prognostic potential depending on the patient population being studied and often have arbitrary thresholds.

Methods: Here, a mathematical and physiological framework to define the patient-specific tipping point of myocardial energetics is defined.

Impact of prophylactic donor heart tricuspid valve annuloplasty on outcomes in heart transplantation.

Background: Tricuspid regurgitation(TR) following heart transplantation could adversely affect clinical outcomes. In an effort to reduce the incidence of TR, prophylactic donor heart tricuspid valve annuloplasty has been performed during heart transplantation in our institution. We assessed early and long-term outcomes.

Standardization of the Right Heart Catheterization and the Emerging Role of Advanced Hemodynamics in Heart Failure.

The accurate assessment of hemodynamics is paramount to providing timely and efficacious care for patients presenting in cardiogenic shock. Recently, the regular use of the pulmonary artery catheter in cardiogenic shock has had a resurgence with emerging data indicating improved survival in the modern era. Optimal multidisciplinary management of advanced heart failure and cardiogenic shock relies on our ability to effectively communicate and understand the complete hemodynamic assessment.

Concomitant left atrial appendage closure during left ventricular assist device surgery can reduce ischaemic cerebrovascular accidents.

Objectives: It remains unknown if the left atrial appendage closure (LAAC) at the time of left ventricular assist device (LVAD) surgery can reduce ischaemic cerebrovascular accidents.

Methods: Consecutive 310 patients who underwent LVAD surgery with HeartMate II or 3 between January 2012 and November 2021 were included in this study. The cohort was divided into 2 groups: patients with LAAC (group A) and without LAAC (group B).

Adverse Hemodynamic Consequences of Continuous Left Ventricular Mechanical Support: JACC Review Topic of the Week.

Left ventricular assist devices (LVADs) provide lifesaving therapy for patients with advanced heart failure. The recognition of pump thrombosis, stroke, and nonsurgical bleeding as hemocompatibility-related adverse events (HRAEs) led to pump design improvements and reduced adverse event rates. However, continuous flow can predispose patients to right-sided heart failure (RHF) and aortic insufficiency (AI), especially as patients live longer with their device.

Human-gained heart enhancers are associated with species-specific cardiac attributes.

The heart, a vital organ which is first to develop, has adapted its size, structure and function in order to accommodate the circulatory demands for a broad range of animals. Although heart development is controlled by a relatively conserved network of transcriptional/chromatin regulators, how the human heart has evolved species-specific features to maintain adequate cardiac output and function remains to be defined. Here, we show through comparative epigenomic analysis the identification of enhancers and promoters that have gained activity in humans during cardiogenesis.

Postoperative tolvaptan use in left ventricular assist device patients: The TOLVAD randomized pilot study.

Purpose: Tolvaptan, a selective vasopressin type-2 antagonist, has been shown to increase serum sodium (Na) and urine output in hyponatremic left ventricular assist device (LVAD) patients in retrospective studies. In this prospective randomized pilot study, we aimed to assess the efficacy of tolvaptan in this population.

Methods: We conducted a prospective, randomized, non-blinded pilot study of LVAD recipients with post-operative hyponatremia (Na < 135 mEq/L) (NCT05408104).
