Silent brain infarcts in high blood pressure patients with cardiac implantable electronic devices: unmasking silent atrial fibrillation
Background: Hypertensive patients present a higher risk for developing atrial fibrillation and its complications. Cardiac implantable electronic devices (CIEDs) have shown reliable atrial fibrillation detection as atrial high-rate episodes (AHREs). The presence of AHRE more than 5 min has been related to increased risk of stroke, but a high proportion of ischemic brain lesions (IBLs) could be subclinical and thromboembolic risk underestimated. Methods: We included hypertensive patients with CIED and we analyzed the incidence of AHRE and the presence of IBL on computed tomography (CT) scan. Results: One hundred and twenty...

The effects of vitamin K supplementation and vitamin K antagonists on progression of vascular calcification: ongoing randomized controlled trials
Conclusion Vitamin K deficiency may be a modifiable cardiovascular risk factor in the haemodialysis population. Conversely, vitamin K antagonists may aggravate VC burden in haemodialysis patients. Several ongoing trials may provide an answer to these questions in the near future.

Limb ischemia, an alarm signal to a thromboembolic cascade - renal infarction and nephrectomy followed by surgical suppression of the left atrial appendage.
We present the case of a 55-year-old male with mild hypertension and brief episodes of paroxysmal self-limiting atrial fibrillation (AF) since 2010. Despite a small cardioembolic risk score, CHA2DS2-Vasc=1 (Congestive heart failure, Hypertension, Age=75, Diabetes melitus, prior Stroke), the patient is effectively anticoagulated using acenocumarol. In December 2014, he showed signs of plantar transitory ischemia, for which he did not address the doctor. In early January 2015, he urgently presented at the hospital with left renal pain, caused by a renal infarction, diagnosed by computed tomography (CT) angiography. Left neph...

Percutaneous left atrial appendage closure followed by single antiplatelet therapy: Short- and mid-term outcomes.
CONCLUSIONS: LAAC using an ACP device followed by single antiplatelet therapy could be a reasonable alternative for stroke prevention. PMID: 28065447 [PubMed - as supplied by publisher]

Effectivity of left atrial appendage occlusion with AtriClip in 155 consecutive patients – Single center study
Conclusions Epicardial clip exclusion of the LAA appears to be a reproducible and safe surgical method with a high success rate. Our follow-up confirmed clip stability, complete occlusion of the LAA, and absence of any AF-related thromboembolic events. These results support regular usage of AtriClip during LAA closure.

Impact of intracranial artery calcification on cerebral hemodynamic changes
ConclusionHeavier IAC might cause generalized artery flow velocity changes and increased pulsatility index, which may indicate high resistance within cerebrovasculature.

Peri-Device Leak after Left Atrial Appendage Closure: Incidence, Risk Factors and Clinical Impact
ConclusionsPDL rate detected by CCTA after LAAC is high, especially in cases with low device compression ratio (<10%), but decreased over time. The incidence of MACE was quantitatively greater with PDL, but the difference was not statistically significant. Larger studies are needed to determine the clinical importance of PDL.

Leukoaraiosis is an independent predictor of intracranial hemorrhage in patients with atrial fibrillation
AbstractWe evaluated the predictive value of several clinical, radiological and laboratory parameters on the risk of predict intracranial hemorrhage (ICH) in patients with atrial fibrillation (AF). We conducted a case-control study on a consecutive hospital based series of patients with AF and ICH. A random sample of subjects with AF without ischemic or hemorrhagic stroke was selected from the same hospital in the same period to perform as the control group, with a ratio of two controls per case. All patients underwent the same evaluation protocol. Patients without neuroimaging exams were excluded. During the study period ...

Peridevice Leak After Left Atrial Appendage Closure: Incidence, Risk Factors, and Clinical Impact
ConclusionsThe PDL rate detected by CCTA after LAAC was high, especially in cases with a low device compression ratio (< 10%), but decreased over time. The incidence of MACE was quantitatively greater with PDL, but the difference was not statistically significant. Larger studies are needed to determine the clinical importance of PDL.RésuméIntroductionPeu d’études ont fait état des taux et des répercussions cliniques des fuites périprothétiques (FPP) après la fermeture de l’appendice auriculaire gauche (AAG) par voie percutanée.MéthodesNous avons inscrit de manière prospective tous les patients consécuti...

Computed Tomography Angiogram: Diagnosing Device Placement Failure
In patients with non-valvular atrial fibrillation (AF) and increased stroke risk, the left atrial appendage (LAA) is a primary source of thrombus [1]. Percutaneous left atrial appendage closure (LAAC), a minimally invasive procedure, is increasingly performed to reduce AF stroke risk [1]. For successful clinical outcomes, it is therefore imperative that the Watchman implant —one such LAA closure device—maintains long-term efficacy. The PROTECT-AF trial, for instance, reported peridevice leak in 32% of patients post-LAAC.

Basilar artery occlusion presenting as sudden bilateral deafness: a case report
ConclusionsWhen hearing loss is due to vertebrobasilar occlusive disease, the prognosis is very poor. We suggest that vertebrobasilar stroke be suspected in patients with bilateral sensorineural hearing loss who present with risk factors for stroke such as atrial fibrillation and other neurologic signs.

Intraparenchymal hemorrhage related to cerebral venous air embolism secondary to mesenteric ischemia
CONCLUSIONS: Mesenteric ischaemia can cause significant pneumatosis intestinalis, which, by a retrograde mechanism through the portal system, can cause air bubbles to reach the cerebral venous system, leading to acute stroke.PMID:33908620 | DOI:10.33588/rn.7209.2020652
