Neuron-specific enolase levels immediately following cardiovascular surgery is modulated by hemolysis due to cardiopulmonary bypass, making it unsuitable as a brain damage biomarker
In conclusion, NSE level immediately after cardiac surgery with CPB is modified by hemolysis rather than brain injury, therefore it would be unreliable as a biomarker of brain disorder.

Detection of inflow obstruction in left ventricular assist devices by accelerometer: A porcine model study
Left ventricular assist devices (LVAD) provide circulatory blood pump support for severe heart failure patients. Pump inflow obstructions may lead to stroke and pump malfunction. We aimed to verify in vivo that gradual inflow obstructions, representing prepump thrombosis, are detectable by a pump-attached accelerometer, where the routine use of pump power (PLVAD) is deficient.

Elective Cardiopulmonary Bypass for Lung Transplantation: Is It Safer Than We Think
The use of cardiopulmonary bypass (CPB) during lung transplantation is controversial. CPB can offer improved visualization, better control of central vasculature, and possibly faster operations. Opponents argue the use of CPB results in higher transfusion requirements, increased rates of primary graft dysfunction (PGD), and more complications such as stroke, acute kidney injury (AKI) and renal failure requiring hemodialysis. In the fall of 2020 our program transitioned to performing all lung transplants on CPB.

Incidence and Impact of Post-Transplant Stroke on Outcomes Following Orthotopic Heart Transplantation Under the 2018 United States Heart Allocation System: A UNOS Registry Analysis
With the increased rate of temporary mechanical circulatory support utilization after the 2018 heart allocation policy change, we sought to quantitate the clinical trends and impact of post-transplant stroke (PTS) and functional independence on outcomes following orthotopic heart transplant (OHT).

Platelet Function and Sildenafil Use During Left Ventricular Assist Device Support
Clinical outcome studies have shown that sildenafil is associated with reduced mortality and thrombotic events such as ischemic stroke during contemporary left ventricular assist device (LVAD) support. Sildenafil has anti-platelet properties but its relation to platelet function during LVAD support is uncertain.

A Retrospective Study on Gender, LAA Morphology and Stroke Risk
This was a retrospective study to investigate whether gender and LAA size/morphology was a predictor of cerebral vascular events in patients undergoing cardiac surgery. We studied the LAA morphology, and measurements for women and men in an attempt to correlate the different morphologies/sizes with the patient's risk of stroke.

Impact of Perioperative Sarcopenia and Dysphagia on LVAD Related Complications
Sarcopenia, as defined by decline in muscle quantity/quality, is prevalent in heart failure and associated with high morbidity and mortality. Sarcopenic dysphagia is caused by sarcopenia in the whole body and swallowing-related muscles. We investigated the impact of perioperative sarcopenia and dysphagia on postoperative pneumonia (PNA), stroke, gastrointestinal bleeding (GIB) and 30-d readmission after LVAD.

Stroke and Survival Outcomes in Left Ventricular Device Patients
Left ventricular assist devices (LVADs) are artificial pumps used for hemodynamic support in patients with end stage heart failure. They can function effectively as a bridge to transplant as well as extend and improve the quality of life of patients. However, these patients are still at a higher risk of stroke, death, and other complications than the average population.

Hemodynamic parameters at rest predicting exercise capacity in patients supported with left ventricular assist device
AbstractLeft ventricular assist devices improve prognosis and quality of life, but exercise capacity remains limited in most patients after device implantation. Left ventricular assist device optimization through right heart catheterization reduces device-related complications. However, hemodynamic parameters associated with exercise capacity under optimized conditions. The aim of this study was to elucidate the predictors of exercise capacity from hemodynamic parameters at rest after left ventricular assist device optimization. We retrospectively reviewed 24 patients who underwent a ramp test with right heart catheterizat...

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 ...
