Impact of anatomical position of the inflow cannula on stroke in patients with left ventricular assist devices.
CONCLUSION: The duct-sep distance to LVDd ratio was associated with the occurrence of stroke, suggesting that inflow cannula position influences the incidence of stroke. PMID: 33472505 [PubMed - as supplied by publisher]

The Effect of Race on Stroke Incidence and Post-Stroke Mortality - The Stroke Paradox in LVAD Patients
Stroke is considered one of the major hurdles in applying Left Ventricular Assist Device (LVAD) technology to a broader population, and remains a leading cause of mortality and morbidity despite advances in both technology and management. In the general population, incidence of stroke in African Americans (AA) has been reported to be twice that of their Caucasian counterparts, and the mortality following stroke higher in AA. We sought to assess the effect of race on both rate of stroke, as well as post stroke survival in the LVAD population.

In-hospital stroke and mortality trends after left ventricular assist device implantation in the United States from 2017 to 2019
CONCLUSIONS: Our study found a significant downtrend in the in-hospital mortality rates among patients with LVAD without substantial changes in stroke rate trends over the study timeframe. As stroke rates remained steady, we hypothesize that improved management along with better control of blood pressure, could have played an important role in survival benefit over the study time frame.PMID:37387231 | DOI:10.1177/03913988231183723

Outflow cannula alignment in continuous flow left ventricular devices is associated with stroke
Int J Artif Organs. 2023 Mar 9:3913988231154284. doi: 10.1177/03913988231154284. Online ahead of print.ABSTRACTWe sought to evaluate whether differences in left ventricular assist device (LVAD) canula alignment are associated with stroke. There is a paucity of clinical data on contribution of LVAD canulae alignment to strokes. We conducted a retrospective analysis of patients who underwent LVAD implantation at Houston Methodist hospital from 2011 to 2016 and included those who had undergone cardiac computed tomography (CT) with contrast. LVAD graft alignment using X-ray, echocardiography, and cardiac CT was evaluated. The ...

Impact of mechanical circulatory support on post-transplant stroke risk
This study assesses if the type of circulatory support device affects stroke risk in this population. The study cohort of 4257 adult patients bridged with mechanical support to cardiac transplant were derived from the UNOS transplant registry data. Risk factors assessed were age, gender, ischemic time, diabetes (recipient), durable mechanical support at listing and mechanical ventilation pre-transplant. Descriptive statistics were used to describe characteristics of the study cohort. Univariate logistic regression was used to test if there is a significant association between stroke event and all the potential risk factors...
