Care for acute ischaemic stroke is one of the most rapidly evolving fields due to the robust outcomes achieved by mechanical thrombectomy. Large vessel occlusion (LVO) accounts for up to 38% of acute ischaemic stroke and comes with devastating outcomes for patients, families and society in the pre-intervention era. A paradigm shift and a breakthrough brought mechanical thrombectomy back into the spotlight for acute ischaemic stroke; this was because five randomised controlled trials from several countries concluded that mechanical thrombectomy for acute stroke offered overwhelming benefits. This review article will present a comprehensive overview of LVO management, techniques and devices used, and the future of stroke therapy. In addition, we review our institution experience of mechanical thrombectomy for posterior and distal circulation occlusion.on July 13, 2020 by guest. Protected by copyright.
A 76-year-old male patient was referred to our institution with moderate-to-severe aortic and mitral insufficiency. The patient underwent totally endoscopic robot-assisted aortic valve replacement and mitral valve repair. In this article, we present our lateral approach to the robotic double valve surgery.
Objective: Barbed nonabsorbable sutures have been widely adopted for tissue closure in noncardiac robotic surgery to improve intraoperative efficiency. Here, we examine the profile in robotic mitral valve repair (rMVR), which utilized barbed nonabsorbable sutures. To our knowledge, this is the first report to describe clinical outcomes for rMVR with barbed nonabsorbable sutures. Methods: A retrospective review identified 90 patients who underwent rMVR using barbed nonabsorbable sutures at our center between 2019 and 2021. The primary outcome measure was dehiscence, while other relevant outcomes included 30-day readmission and 30-day mortality. Results: In addition to fixation of the mitral annuloplasty band, barbed nonabsorbable sutures were employed commonly in concomitant pericardiectomy closure (100.0%, 90 of 90), atriotomy closure (100.0%, 90 of 90), and left atrial appendage closure (if eligible; 98.8%, 83 of 84). One patient who underwent mitral valve annuloplasty using only barbed nonabsorbable suture required reoperation for annuloplasty ring dehiscence. Immediate postoperative ring dehiscence was not observed in any patients after the routine reinforcement of barbed nonabsorbable sutures with everting pledgeted polyester sutures, and no additional patients required reoperation for suture-related complications. Clinical signs of dehiscence were not observed after pericardiectomy, atriotomy, or left atrial appendage closure with barbed nonabsorbable sutures. The 30-day readmission rate was 3.3% (3 of 90), and 30-day mortality was 0% (0 of 90). Conclusions: These data suggest the initial feasibility of barbed nonabsorbable sutures in robotic cardiac surgery, specifically within rMVR. Further research is necessary to explore the long-term safety and efficacy profile of such approach.
Introduction:
Inflammatory markers, such as C-reaction protein (CRP), have been shown to be highly associated with cardiovascular disease. However, it is unclear if baseline levels of cardiovascular fitness in young, healthy persons are related to inflammatory biomarkers who have not yet manifested cardiovascular disease.
Methods:
Data was compiled from the National Health and Nutrition Examination Survey (NHANES). Cardiovascular fitness level (low, moderate, high) was categorized by estimated VO2 max (with age/sex adjustment cut points). Associations with CRP-based cardiovascular risk were analyzed using ANOVA/Kruskal-Wallis and Chi-squared. Ordered logistic regression was employed to identify predictors of increasing CRP-based cardiovascular risk. To account for the complex survey design, all analyses were conducted using appropriate estimated weights following NHANES analytic guidelines.
Results:
2,201 participants from 1999-2004 from ages 12-49 completed cardiovascular fitness testing and had full laboratory analysis. A sensitivity analysis was performed grouping participants into CRP-based cardiovascular risk categories (low <1mg/L, moderate 1-3 mg/L, high >3 mg/L) based on the 2003 AHA/CDC Scientific Statement. Increase in cardiovascular fitness category was associated with decrease in CRP-based cardiovascular risk (OR 0.83, 95% CI 0.75 to 0.91, p<0.001). The relationship was strengthened (OR 0.77, 95% CI 0.68 to 0.87, p<0.001) when adjusting for age, sex, BMI, diabetes, and smoking.
Conclusions:
In a sample representative of the United States civilian non-institutionalized population, lower levels of cardiovascular fitness were associated with increased inflammatory biomarkers related to cardiovascular risk, even with adjustment for fitness-related covariates. Further studies will help us to understand the therapeutic role on VO2 max and cardiovascular fitness improvement in reducing atherosclerosis-related inflammation.
These mechanical and functional differences provide the framework through which we examine the current status and future possibilities of the abdominal and thoracic artificial organs.Expert Opinion: Transforming the artificial organs landscape in ways that expand the scope of existing device capabilities and improve the clinical utility of artificial organs will require making improvements upon existing technologies and multidisciplinary cooperation to create and discover new capacities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
