Advancements in left ventricular assist devices to prevent pump thrombosis and blood coagulopathy
J Anat. 2022 Apr 20. doi: 10.1111/joa.13675. Online ahead of print.ABSTRACTMechanical circulatory support (MCS) devices, such as left ventricular assist devices (LVADs) are very useful in improving outcomes in patients with advanced-stage heart failure. Despite recent advances in LVAD development, pump thrombosis is one of the most severe adverse events caused by LVADs. The contact of blood with artificial materials of LVAD pumps and cannulas triggers the coagulation cascade. Heat spots, for example, produced by mechanical bearings are often subjected to thrombus build-up when low-flow situations impair washout and thus th...

Assessment of Hypertension, Guideline-Directed Counseling, and Outcomes in the ACHD Population
AbstractGuidelines for the diagnosis and treatment of hypertension were published by the American Heart Association (AHA) in 2017. The prevalence of hypertension in adults with congenital heart disease (ACHD) under these guidelines has yet to be characterized. We sought to assess the prevalence, impact, and provider response to hypertension under current guidelines. Data were obtained retrospectively from records of routine clinic visits over a 10 year period. Potential hypertension-related adverse outcomes including stroke, myocardial infarction, surgical intervention for aortic aneurysm, aortic dissection, atrial fibri...

Data from New VOYAGER PAD Analyses at ACC.22 Reinforce Benefit of XARELTO ® (rivaroxaban) Plus Aspirin in Patients with Peripheral Artery Disease (PAD) and Various Co-Morbid Conditions
RARITAN, N.J., April 1, 2022 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced data from new analyses from the Phase 3 VOYAGER PAD clinical trial reinforcing the benefit of the XARELTO® (rivaroxaban) vascular dose (2.5 mg twice daily plus aspirin 100 mg once daily) in reducing severe vascular events in patients with PAD after lower-extremity revascularization (LER), a procedure that restores blood flow to the legs. Data from the two analyses demonstrate the role that the XARELTO® vascular dose plays in PAD patients with and without chronic kidney disease (CKD) and in PAD patients with and ...

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

Optimization of Left Ventricle Size After VAD Implantation Prevents Incidence of Cerebral Infarction
Stroke after ventricular assist device (VAD) implantation is a critical complication. Previous studies have noted the distance between the inflow cannula and the left ventricular (LV) septum, as well as an angulation of the inflow cannula from the apical axis, related to the incidence of stroke. In the early phase after VAD implantation, diuresis is caused by improved renal blood flow, furthermore, rapid volume reduction of LV greatly changes circulating plasma volume, resulting in increased stroke risk; however, little is known about an appropriate indicator for the prevention of this phenomenon.

Unique Findings of Myocardial Improvement with Lower Left Ventricular Assist Device Pump Speed
Currently, optimizing hemodynamics and unloading in patients with left ventricular assist device (LVAD) relies on echocardiography and right heart catherization guidance for pump speed adjustments. However, the ideal unloading strategy to maximize reverse remodelling is uncertain - whether to provide maximal pump support to unload the heart ( ‘rest’), or maximize ventricular work with partial pump support (‘work’). Using non-invasively derived PV loops, we sought to characterize the longitudinal changes in chamber contractile parameters stroke work (SW), peak systolic pressure (LVPmax) and peak LV elastance (Ees) a...

A Prospective Randomized Trial Comparing Stroke Volume Measurements by Esophageal Doppler and Pulse-Contour Analysis During a Fluid Resuscitation Protocol in Brain-Dead Organ Donors
Maximizing stroke volume (SV) is the optimal method of fluid resuscitation. Both the esophageal doppler (EDM) and pulse contour analysis (PCA) are validated methods of measuring SV in critical patients, but neither have not been well-studied in the brain-dead (BD) donor. We have previously published our fluid resuscitation protocol in BD donors demonstrating a significant reduction in time on vasopressors from 16 hours in the control group to 2.9 hours in the protocol group. We performed a prospective randomized trial comparing the effectiveness of the EDM and PCA in this fluid resuscitation protocol in BD donors.

Who is at Risk for Seizures After Heart Transplantation?
Seizures may occur following heart transplantation (HTx), especially since tacrolimus can lower a seizure threshold. HTx recipients are also at high stroke risk given many patients have existing cerebrovascular disease. The purpose of the study was to assess the prevalence and risk factors for seizures in HTx recipients at our center.

Carotid Endarterectomy Prior to Ventricular Assist Device Placement in a Patient with Cardiogenic Shock
Atherosclerotic disease in the cervical vessels may be a contraindication for implantation of left ventricular assist devices (LVADs). The occurrence of ischemic stroke represents an obstacle to rehabilitation, and its incidence seems to be higher in this population. Carotid endarterectomy (CEA) is a preferable surgical treatment in patients with high bleeding risk. This case report suggests that CEA followed by implantation of LVADs can be feasible.

Assessing Cardiac Recovery for Decommissioning of LVAD Support: Structure versus Function
Recovery of left ventricular (LV) function during LVAD support occurs in only 1-3% of patients. Assessment for recovery and LVAD removal is desirable given the risks of infection, stroke, and device malfunction. This case of a patient with an LVAD, with recovered LV systolic function but abnormal exercise hemodynamics, illustrates the potential utility of right heart catheterization studies for clinical decisions.
