First baby born after uterus transplant from deceased donor
The first baby gestated in a uterus transplanted from a cadaver has been born in Brazil, according to a case reported in the medical journal The Lancet. The 32-year-old mother, who was born without a uterus, underwent a 10-hour transplant surgery in 2016 then underwent fertility treatment, the BBC reported. The donor was a woman in her 40s who died from a stroke. The mother’s eggs were removed from her ovaries, fertilized with the father’s sperm, then implanted in the donor urerus after the…
ConclusionCardiac resynchronization therapy seems to be less efficient in LMNA patients compared to usual implanted patients with other type of advanced cardiomyopathy. An impaired right ventricular stroke function seems to be the only predictive factor leading to poor response to CRT.
Sickle cell disease (SCD) is one of the most common hereditary hemoglobinopathies worldwide, affecting almost 400,000 newborns globally each year. It is characterized by chronic hemolytic anemia and endothelial dysfunction, resulting in a constant state of disruption of the vascular system and leading to recurrent episodes of ischemia-reperfusion injury (I/RI) to multiple organ systems. I/RI is a fundamental vascular pathobiological paradigm and contributes to morbidity and mortality in a wide range of conditions, including myocardial infarction, stroke, acute kidney injury, and transplantation.
Abbott (NYSE:ABT) yesterday presented data from a new trial of its HeartMate 3 left ventricular assist device, touting a reduced rate of strokes, pump-related blood clots and bleeding episodes at two years as compared with the previous generation HeartMate II. Data in the trial was presented at the American College of Cardiology’s 68th Annual Scientific Session 2019 in New Orleans and published simultaneously in the New England Journal of Medicine, the Chicago-area medical device company said. Abbott touted its HeartMate 3 as the first implantable mechanical pump using fully magnetic levitation technology, makin...

AlexanderAbstractIschemia-reperfusion injury (I/RI), produced by an initial interruption of organ blood flow and its subsequent restoration, contributes significantly to the pathophysiologies of stroke, myocardial infarction, renal I/RI, intestinal I/RI and liver I/RI, which are major causes of disability (including transplant failure) and even mortality. While the restoration of blood flow is required to restore oxygen and nutrient requirements, reperfusion often triggers local ...
Although regions of stasis such as the left atrial appendage (LAA) may be potential sites of thrombus formation during atrial fibrillation (AF), its thrombotic contribution during high flow mechanical unloading is unknown. Moreover, registry studies only show a mixed association of AF and stroke during continuous flow left ventricular assist device (CF LVAD) support. Since a lower peak Left Atrial Appendage Emptying Velocity (LAAEV) of less than 40 cm/s during AF, mechanistically contributes to thrombosis and stroke in non-CF LVAD populations, we sought to evaluate the LAAEV in CF LVAD patients with and without AF.
This report describes baseline AC data from ACTION centers, including agents used and aggregate levels of performance, to inform development of specific interventions.
Ventricular assist device (VAD) patients experience infections, which increase the risk of stroke and mortality. We aimed to characterize key differences in clinical outcomes for VAD patients based on the ISHLT categorization of infections: VAD-specific (e.g. pump component related), VAD-related (e.g. bloodstream infection, BSI) and non-VAD infections (e.g. pneumonia).
In the normal, pulsatile circulation, the hemodynamic pattern of the middle cerebral artery (MCA) differs from the central retinal artery (CRA). Whether continuous flow from a left ventricular assist device (LVAD) alters this relationship is not known. Since serious adverse events in different end-organs, such as stroke and GI bleeding, are frequent in LVAD patients, comparing hemodynamics in different arterial beds may enhance our understanding of the specific pathophysiology of these complications.
Stroke is a major complication with potentially devastating consequences for patients receiving veno-arterial extracorporeal membrane oxygenation (VA-ECMO). Arterial cannulation sites for VA-ECMO include ascending aorta, axillary artery, and femoral artery. However, rates of stroke according to cannulation site are currently unknown. The purpose of this study was to investigate the association between occurrence and patterns of stroke with ECMO arterial cannulation sites.
Patients with advanced HF are at increased risk for intra-cardiac thrombus formation. The impact of pre-existing left atrial (LA) or left ventricular (LV) thrombi on post-operative outcomes in LVAD patients is unknown.
