Prolonged Circulatory Arrest is Not Associated with Stroke or Mortality after Pulmonary Thromboendarterectomy
Patients with chronic thromboembolic pulmonary hypertension (CTEPH) frequently present with extensive distal clot burden, which adds complexity to pulmonary thromboendarterectomy (PTE). Complete endarterectomy often necessitates prolonged periods of hypothermic circulatory arrest (HCA), the ramifications of which are poorly understood. Objectives were to describe the association of HCA time with post-operative neurologic complications, operative mortality and other major morbidity after PTE.

Improvement in Right Ventricular Stroke Work Index in Cardiogenic Shock Associated with Excellent Durable Left Ventricular Assist Implantation Results
Cardiogenic shock results from inadequate cardiac output to satisfy organ perfusion with potential need for pharmacologic and mechanical circulatory support for survival. Impella 5.0 insertion is used as a rescue device and bridge to durable mechanical circulatory support. We sought to evaluate changes in right ventricular parameters in patients bridged with Impella 5.0 undergoing durable left ventricular device implantation (LVAD).

Incidence, Predictors and Outcomes of Stroke Following Cardiac Transplantation
Stroke after heart transplantation (HT) is a major cause of morbidity and mortality. Less is known about the risk factors associated with stroke in the current era of increasing HT being performed in older patients and with advances in immunosuppressive (IS) therapies. We aimed to determine the incidence, predictors and outcomes of stroke after HT.

Prognostic Role of Simultaneous Assessment of Biventricular Function Using Left Ventricular Stroke Work Index and Right Ventricular Stroke Work Index
We hypothesized that simultaneous assessment of biventricular function could predict clinical outcomes.

Elevated Blood Pressure Before Left Ventricular Assist Device Support Implant is Associated with an Increased Risk of Stroke
Despite the recent advances in Left Ventricular Assist Device (LVAD) therapy, stroke remains a frequent and catastrophic complication. Hypertension (HTN) after LVAD implant has been associated with an increased risk of stroke, but the association between HTN before LVAD implant and stroke has never been studied. We hypothesized that LVAD patients with elevated blood pressure (BP) during outpatient visits before the LVAD implant may have an increased risk of stroke.

Clinical Characteristics and Outcomes of Extracorporeal Membrane Oxygenation Support in COVID-19: Retrospective Study of Single Center Experience
This study is to summarize the clinical features, and outcomes of patients with severe ARDS due to COVID-19 treated with ECMO. We analyzed the incidence of morbidity including ischemic/hemorrhagic stroke, gastrointestinal bleeding, pump malfunction, oxygenator dysfunction, infection during VV ECMO.

Risk of Stroke in Patients with Left Ventricular Assist Device Who Had Myocardial Recovery
The risk factors and incidence rates of stroke after implantation of left ventricular assist devices (LVAD) are well established. Little is known about the factors associated with stroke after LVAD explantation in patients who have had a myocardial recovery.

Bridge from Central Extracorporeal Life Support to Durable LVAD in Acute Heart Failure Elevates a Risk of Stroke Long-Term
This study aimed to review outcomes of this bridge strategy from central ECLS to durable LVAD, as compared to those of primary LVAD implantation.

HVAD Lavare Cycle Reduces Cerebrovascular Events and Improves Survival
The Lavare Cycle (LC) is a pre-programmed speed modulation algorithm in the HVAD device designed to automatically increase both ventricular and pump washing. The ReVOLVE trial suggested a reduction in adverse outcomes including stroke. We assessed the effect LC ON compared to LC OFF on HVAD implants.

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.
