Transcatheter aortic valve thrombosis: the relation between hypo-attenuated leaflet thickening, abnormal valve haemodynamics, and stroke

ConclusionOn MDCT, 12.5% of patients showed HALT or reduced leaflet motion, whereas only one of these patients had abnormal valve haemodynamics on echocardiography. Neither HALT nor increased transvalvular gradient were associated with stroke/TIA.

This review of current literature provides background to the COVID-19 pandemic, as well as an examination of potential pathophysiologic mechanisms behind development of thrombosis and ischemic stroke related to COVID-19. SARS-CoV-2 infection is well-documented to cause severe pneumonia, however, thrombosis and thrombotic complications, such as ischemic stroke, have also been documented in a variety of patient demographics. SARS-CoV-2 infection is known to cause a significant inflammatory response, as well as invasion of vascular endothelial cells, resulting in endothelial dysfunction.

We present a patient with COVID-19 pneumonia who was managed with unfractionated heparin (UFH) infusion and developed a large ischemic infarct shortly after cessation of the infusion. In retrospect, the patient's coagulation parameters were consistent with overt DIC, although some of these parameters are easily masked by the effects of UFH. These findings emphasize the importance of anticoagulation as well as its careful discontinuation, as failure to do so may result in a significant thromboembolic event.

ConclusionsThe H-REPLACE trial offers an opportunity to assess clinical outcomes of rivaroxaban versus enoxaparin during the acute phase of ACS and may provide an alternative anticoagulation strategy for ACS patients, who missed the primary reperfusion therapy window and before selective revascularization.Trial; NCT03363035.

CONCLUSION:  Our results suggested that the combination of the HDAC3 and HDAC9 genes with a history of diabetes mellitus could exacerbate the deterioration of atherosclerosis, thereby increasing the risk of IS. Further studies are warranted to explore our results in other populations. PMID: 32961570 [PubMed - as supplied by publisher]

CONCLUSIONS: Recurrent stroke and intracranial hemorrhage were determined to be more prevalent at 5 years after TIA or minor stroke in Japanese patients than in non-Japanese patients. Strategies to mitigate the long-term risks of stroke, aside from adherence to current guidelines, should take Japanese-patient-specific residual risks into account.

We present four cases of coronavirus disease 2019 ischemic strokes occurring in patients aged 37–68 yrs with varying coronavirus disease 2019 infection severities, premorbid risk factors, clinical presentations (eg, focal and nonfocal), and vascular distributions. These cases highlight the heterogeneity of coronavirus disease 2019 ischemic strokes. The duration of the coronavirus disease 2019–related prothrombotic state is unknown, and it is unclear whether patients are at risk for recurrent strokes. With more coronavirus disease 2019 patients recovering and being discharged to rehabilitation, physiatric awaren...

We report a case of ischemic stroke in the area of a DVA after minor head trauma in a patient with DVA and without a predisposition thrombosis. Patient concerns: A healthy 17-year-old male was admitted to the emergency room due to left hemiparesis, which was caused by a ball hitting the right side of his head during a soccer game. Diagnosis: Brain magnetic resonance (MR) susceptibility-weighted image showed several small veins draining to the central vein in the area from the right posterior putamen to the periventricular white matter. Interventions: We diagnosed the patient with an ischemic stroke associated with...

Stroke is one of the leading causes of morbidity and mortality worldwide, and it is increasing in prevalence. The limited therapeutic window and potential severe side effects prevent the widespread clinical application of the venous injection of thrombolytic tissue plasminogen activator and thrombectomy, which are regarded as the only approved treatments for acute ischemic stroke. Triggered by various types of mild stressors or stimuli, ischemic preconditioning (IPreC) induces adaptive endogenous tolerance to ischemia/reperfusion (I/R) injury by activating a multitude cascade of biomolecules, for example, proteins, enzymes...

Abstract Acute ischemic stroke is a neurological emergency with a high likelihood of morbidity, mortality, and long-term disability. Modern stroke care involves multidisciplinary management by neurologists, radiologists, neurosurgeons, and anesthesiologists. Current American Heart Association/American Stroke Association (AHA/ASA) guidelines recommend thrombolytic therapy with intravenous (IV) alteplase within the first 3-4.5 hours of initial stroke symptoms and endovascular mechanical thrombectomy within the first 16-24 hours depending on specific inclusion criteria. The anesthesia and critical care provider may b...
