Impact of postoperative acute kidney injury on short-term outcomes of patients with Bentall surgery for any reason
CONCLUSION: Patients undergoing Bentall surgery who postoperatively developed AKI showed significantly higher morbidity and mortality. AKI points out to be an early predictor for poor outcomes. Thus, as a consequence, patients with postoperatively developed AKI should be highly monitored for immediate intervention.PMID:35099323 | DOI:10.1177/02676591211073865

Intravenous thrombolysis for acute ischemic stroke: why not?
Purpose of review The aim of this study was to summarize available evidence regarding the safety and efficacy of intravenous thrombolysis (IVT) using recombinant tissue-plasminogen activator (rt-PA) in acute ischemic stroke (AIS) patients with specific comorbidities and potential contraindications to systemic reperfusion therapy. Recent advances in IVT implementation in wake-up stroke and in extended time window using advanced neuroimaging will also be highlighted. Recent findings Despite theoretical concerns of a higher bleeding risk with IVT, there are no data showing increased risk of symptomatic intracerebra...

Clinical results and 30-day outcomes of self-expanding transcatheter aortic valves: comparative case-matched analysis of CoreValve < sup > ® < /sup > versus ACURATE neo ™
CONCLUSION: Both self-expandable prostheses showed good postoperative hemodynamic performance with a low incidence of severe paravalvular leakage, all- cause mortality, and comparable clinical outcomes.PMID:34472999 | DOI:10.1177/02676591211042562

Cerebral Autoregulation in Subarachnoid Hemorrhage
Subarachnoid hemorrhage (SAH) is a devastating stroke subtype with a high rate of mortality and morbidity. The poor clinical outcome can be attributed to the biphasic course of the disease: even if the patient survives the initial bleeding emergency, delayed cerebral ischemia (DCI) frequently follows within 2 weeks time and levies additional serious brain injury. Current therapeutic interventions do not specifically target the microvascular dysfunction underlying the ischemic event and as a consequence, provide only modest improvement in clinical outcome. SAH perturbs an extensive number of microvascular processes, includi...

Outcome of right ventricular assist device implantation following left ventricular assist device implantation: Systematic review and meta-analysis
CONCLUSION: Implantation of a temporary RVAD is allied with a worse outcome during the primary hospitalization and at follow-up. Compared to isolated LVAD support, biventricular mechanical circulatory support leads to an elevated mortality and higher incidence of adverse events such as bleeding and stroke.PMID:34112048 | DOI:10.1177/02676591211024817

Aortic dissection diagnosed on stroke computed tomography protocol: a case report
ConclusionsWhen acute stroke is suspected due to neurological deficits, plain head CT is the first choice for imaging diagnosis. The addition of cervical CT angiography can reliably exclude stroke due to aortic dissection. CTP can identify ischemic penumbra, which cannot be diagnosed by plain head CT or diffusion-weighted magnetic resonance imaging. These combined stroke CT protocols helped us avoid missing an aortic dissection.

Cerebral blood volume Alberta Stroke Program Early Computed Tomography Score predicts intracranial hemorrhage after thrombectomy in patients with acute ischemic stroke in an extended time window.
CONCLUSION: Low CBV-ASPECTS independently predicts ICH in patients with AIS treated with thrombectomy selected by CTP in an extended time window. PMID: 33541090 [PubMed - as supplied by publisher]

Aortoesophageal fistula involving the central aortic arch salvaged with emergent percutaneous TEVAR, great vessel coverage and in vivo graft fenestration.
We describe an unusual and challenging case of TEVAR coverage of an AEF involving the central aortic arch immediately followed by in vivo endograft fenestration to regain arch vessel perfusion. In vivo fenestration, currently a procedure for emergency or investigational purposes only, was shown to be life saving in our case. The main complications associated with the procedure included stroke and infection, requiring esophagectomy and cervical diversion as well as ongoing antibiotic treatment.

Single-Stage Treatment of Extensive Aortic Pathology Using the Frozen Elephant Trunk Procedure.
CONCLUSION: The frozen elephant trunk procedure can be used for a single-stage treatment of patients with extensive aortic pathology, due to chronic degenerative aneurysms or post-dissection aneurysms involving the aortic arch and the descending aorta, with acceptable mortality and morbidity.

Atrial Fibrillation and Dementia.
Abstract Atrial fibrillation is associated with multiple adverse comorbidities, including the development of dementia in patients with and without a history of stroke. Mechanistic models have been proposed to explain the association of AF and dementia. Alterations of brain perfusion from embolic events, bleeding, and rhythm-related hypoperfusion underlie many of these models. Multiple mediators such as oxidative injury, inflammatory and autoimmune mechanisms, and genetic predisposition also interplay in the disease association. There are potential therapeutic opportunities to reduce dementia risk, including early ...

Clinical and Radiological Outcomes After Revascularization of Hemorrhagic Moyamoya Disease
Conclusion: Direct revascularization may be superior to indirect revascularization for prevention of rebleeding and poor neurological outcome in adults with hemorrhagic MMD. The risk of postoperative rebleeding was higher in those with untreated aneurysms, repetitive bleeding episodes, normal perfusion status, and indirect revascularization. The regression of original collaterals and establishment of revascularization collaterals after revascularization were more significant in hemispheres with direct revascularization than those with indirect revascularization.

Limited versus extended repair for acute type A aortic dissection: long-term outcomes of the Beijing approach beyond 10 years.
CONCLUSIONS: In this large series of ATAAD, the FET + TAR technique has achieved satisfactory early and long-term survival and freedom from reoperation up to 15 years. Marfan syndrome and malperfusion syndrome were risk factors for early and late mortality and distal reoperation. This study adds long-term evidence supporting the use of the FET + TAR technique in patients with ATAAD involving the arch and descending aorta. PMID: 32077675 [PubMed - as supplied by publisher]

Novel Embolic Protection Device: a Feasibility Study
AbstractStroke is ranked as the second leading cause of death worldwide. Ischemic stroke commonly results from emboli that originate in the heart among high-risk patients, such as those who develop atrial fibrillation. Yet, treatment is currently limited to anticoagulants, which may be associated with life-threatening bleeding. Our aim was to develop an alternative, device-based approach for continuous stroke prevention in high-risk patients. To this end, a novel endovascular tubular mesh was designed to be implanted in the aortic arch and to reroute emboli away from critical cerebral arteries. The feasibility of this appr...
