Valve-in-valve transcatheter aortic valve implantation versus repeat surgical aortic valve replacement in patients with a failed aortic bioprosthesis
CONCLUSIONS: ViV TAVI was associated with lower in-hospital mortality but higher 30-day and 6-month all-cause readmission. However, there was no difference in risk of in-hospital stroke, post-procedure pacemaker implantation, MACE, and mortality during 30-day and 6-month readmission compared with repeat SAVR, suggesting that ViV TAVI can be performed safely in carefully selected patients.PMID:34521614 | DOI:10.4244/EIJ-D-21-00472

EP58 Procedural and functional outcomes for aspiration thrombectomy in acute ischemic stroke patients with differing clot dwell times: A subset analysis from the COMPLETE registry
ConclusionsPatients with longer clot dwell times were associated with more attempts and longer time to achieve reperfusion, more post-procedure complications, and lower likelihood of functional recovery.DisclosureOsama O.

NODDI highlights recovery mechanisms in white and gray matter in ischemic stroke following human stem cell treatment
CONCLUSIONS: NODDI compliments DTI metrics, enhances interpretation of tissue outcome in ischemic stroke following hMSC application, and may be useful in evaluating or predicting therapeutic response.PMID:34355818 | DOI:10.1002/mrm.28929

Characterizing Intraoperative Vasopressor Use in Total Knee Arthroplasty: A Retrospective Cohort Study
In conclusion, nearly 59% of patients undergoing TKA received intraoperative vasopressor support. History of stroke and older age were significantly associated with increased intraoperative vasopressor use. As the first study to examine vasopressor usage in a TKA patient population, we believe that understanding the association between patient characteristics and intraoperative vasopressor support will help orthopaedic surgeons select the appropriate surgical setting during preoperative optimization.

E-105 Analysis of clinical associations of serum SCFAs taken at the time of thrombectomy in AIS patients
ConclusionsThe evaluation of SCFAs in the serum at the time of stroke provides novel insight into the potential role of SCFAs during stroke in human patients. Age remains a significant factor to SCFA concentrations in stroke patients. The length of time following stroke also contributes to the levels of SCFAs. Previous studies have shown that increased levels of SCFAs is associated with decreased severity of stroke, however our data did not detect any such effect. This observation may be due to the acute time of the blood collection following stroke and analyzing serum instead of fecal samples. Furthermore, acquiring infor...

O-032 Treatment outcomes for ARUBA eligible brain arteriovenous malformations: a comparison of real world data from the NVQI-QOD AVM registry to the ARUBA trial
ConclusionARUBA eligible patients from the NVQI-QOD registry demonstrate a significantly lower risk of stroke or death with intervention of 8.0% (N=174) compared to the 30.7% (N=114) ARUBA trial interventional risk, and is nearly equivalent to the ARUBA trial medical management risk of 10.1% (N=109) over 33 months.Disclosures N.

P-026 Aqua embolic system: evaluating the performance of a new liquid embolic system using a swine AVM model
ConclusionsAES, which is a DMSO free, non-adhesive polysaccharides based LEM, may be used as an embolic material for the treatment of hemorrhagic stroke caused by cerebrovascular diseases, such as brain AVM.A: common carotid artery injection (AP view) shows left ascending pharyngeal artery (APA) and left rete mirabile (red arrow). B: AES is injected from the microcatheter. The AES reflux is reaching the tip of the microcatheter. C: With continuous injection of AES, the microcotheter tip is embedded ¡n the cost of AES. D. Post treatment angiogram shows complete occlusion of the left rete mirabile and APADisclosures I....

Disentangling the Psycholinguistic Loci of Anomia with Cognitive Psychometric Models
This article reviews advanced statistical techniques for measuring impairments in object naming, particularly in the context of stroke-induced aphasia. Traditional testing strategies can be challenged by the multifaceted nature of impairments that arise due to the complex relationships between localized brain damage and disruption to the cognitive processes required for successful object naming. Cognitive psychometric models can combine response-type analysis with item-response theory to yield accurate estimates of multiple abilities using data collected from a single task. The models also provide insights about how the te...
