Mean Arterial Pressure is Not Associated with Hemocompatibility-Related Outcomes in LVAD Patients
Elevated mean arterial pressure (MAP) is associated with stroke in patients with HeartMate II and Heartware HVAD left ventricular assist devices (LVADs). We assessed the relationship between mean arterial pressure (MAP) and hemocompatibility-related clinical adverse events (HRAE) in patients with LVADs.

Effects of ACE Inhibitors, Angiotensin Receptor Blockers and Angiotensin Receptor-Neprilysin Inhibitors on Survival Free from Gastrointestinal Bleeding in HeartMate 3 Patients - A Marginal Structural Modeling Analysis
The HeartMate 3 (HM3) is superior to HMII in survival free from disabling stroke and pump exchange, however, rates of GIB remain high. Prior studies show a protective effect of digoxin and ACEi/ARB on risk for GIB, whereas phosphodiesterase 5 inhibitors (PDE5i) have opposite effect in HMII using Cox Proportional Hazard (PH) models with inverse probability weighting (IPW). Compared to this approach, marginal structural modeling (MSM) accounts for time-dependent confounding thereby producing results closer to true causal effect.

Arterial Pulsatility in Patients with Continuous Flow Left Ventricular Assist Device Support: Comparing Velocity and Mean Arterial Pressure
An increasing number of end-stage heart failure patients are supported by continuous-flow Left Ventricular Assist Devices (cfLVADs) as a bridge to heart transplantation. Accurate assessment of arterial pulsatility remains a challenge because of diminished pulse pressure, which itself can be associated with adverse events such as gastrointestinal bleeding and stroke. Our study investigates the value of simultaneous arterial pressure and arterial blood velocity assessment in cfLVAD patients.

Aortic and Renal Artery Thrombosis as the First Clinical Manifestation of COVID-19 in a Heart Transplant Recipient
The relation between coronavirus 2019 disease (COVID-19) and thrombotic events is well established, and both arterial and venous thrombotic events are described. Although arterial events occur in about 3.6 to 10.5% of critically ill patients, they are usually stroke or acute myocardial infarction. Arterial thrombosis of other sites is rare.

A Comparative Analysis of Long-Term Outcomes in the MOMENTUM 3 Pivotal Trial and Continued Access Protocol Post-Approval Study Phase: A Study of over 1500 HeartMate 3 Implants
The MOMENTUM 3 pivotal trial conducted from 2014 to 2018 evaluated safety and effectiveness of the HeartMate 3 (HM3) left ventricular assist system (LVAS) compared to the HeartMate II pump. The trial demonstrated superiority of the HM3 LVAS for the primary endpoint of survival free of disabling stroke or reoperation to replace a malfunctioning pump at 2-years. HM3 LVAS superiority was due to improved hemocompatibility with near-elimination of device thrombosis, halving of stroke rates, and a decrease in gastrointestinal bleeding rates compared to the control device.

The ABC's of Stroke Prevention: Reduction in Stroke Frequency Following a Quality Improvement Intervention by the Action Learning Network
To assess the frequency of stroke among ventricular assist device patients following a quality improvement bundled intervention (the “ABCs of Stroke Prevention” [ABCs] which focused on Anticoagulation, Blood pressure, and Communication) within the Advanced Cardiac Therapies Improving Outcomes Network (ACTION). The bundle intervention comprised 3 interventions. These were: a document harmonizing how to implement and maintain b ivalirudin infusion, a blood pressure management protocol and a daily stroke prevention checklist.

Simultaneous Multi-Vascular Bed Imaging in a Patient Supported by a Continuous-Flow LVAD
Patients supported with left ventricular assist devices (LVADs) are burdened by frequent hemocompatibility-related adverse events related to patient-pump interactions. These predominantly vascular events include stroke, gastrointestinal bleeding, and pump thrombosis. Our center performs routine, invasive hemodynamic ramp speed titrations in LVAD patients to determine the optimal rotational speed after implantation. We sought to interrogate changes in vascular hemodynamics during an exercise ramp study to understand the influence of pump speed and exercise on outflow graft and cerebrovascular flow.

Stroke in pediatric ventricular assist device patients-a pedimacs registry analysis
Cerebral vascular accidents (CVA) are common complications of pediatric ventricular assist devices (VAD). We employed the Pediatric Interagency Registry for Mechanical Circulatory Support (Pedimacs) to investigate rates, risk factors, and outcomes of CVA in pediatric patients supported on VAD.

Cardiac Transplantation for Cancer Involving the Heart
Cardiac Cancer (CC) that arises from or involves the heart can present as heart failure, chest pain, stroke or another thromboembolic event. Although patients with CC have limited treatment options, in other organ cancers such as hepatocellular carcinoma, liver transplant improves 5-year overall survival in carefully selected patients1. For CC, however, the benefit of replacing the cancerous heart is uncertain because one-year survival is generally estimated around 50% after this rare operation.

Hypertension, Arterial Compliance and LVAD Pump Function
Hypertension (HTN) has been implicated as a risk factor for stroke in continuous-flow Left Ventricular Assist Device (LVAD) populations. Active treatment of HTN has been shown to decrease cerebrovascular accident rates in the recent trial. Current guidelines recommend a mean arterial pressure (MAP) of 80mmHg in LVAD patients; however, it is difficult to reliably measure Blood Pressure (BP) in this cohort. Increased BP will further affect pump output since LVAD flows are altered by both preload and afterload.

Intracorporeal VAD Outcomes in the ACTION Quality Improvement Network
The initial project of ACTION (Advanced Cardiac Therapies Improving Outcomes Network) is focused on improving stroke rates in patients implanted with a ventricular assist devices (VAD) in participating centers. The initial interventions targeted improving communication, anticoagulation, and blood pressure management. We sought to describe the characteristics and outcomes of patients implanted with intracorporeal, continuous flow VADs (cfVAD).

Pulmonary Vascular Resistances among Heart Transplant Candidates: Are We Looking to the Right Player?
Pulmonary vascular resistances (PVR) are among the key measurements derived from right heart catheterization (RHC) in the prognostic assessment of patients (pts) candidate to Heart Transplantation (HT). PVR however don't account for compliance and pulsatility of pulmonary circulation. Pulmonary arterial compliance (PAC) [stroke volume/pulmonary artery pulse pressure (SV/PAPP)], that is inversely related to PVR, and pulmonary effective arterial elastance (Ea) (sPAP/SV) incorporate compliance and pulsatility of right ventricular afterload.
