RESUMO
Previous reports comparing transcarotid (TC) versus transfemoral (TF) approaches for patients undergoing transcatheter aortic valve replacement have had inconsistent conclusions. We compared in-hospital and 1-year clinical outcomes, changes in quality of life, and direct hospital costs for 138 TC versus 1,926 TF procedures. Propensity matching based on the Society of Thoracic Surgery Predicted Risk of Mortality was used to compare 130 patients who underwent TC with 813 patients who underwent TF. Matched TC versus TF cohorts did not differ with respect to in-hospital mortality (0.0% vs 1.4%, p = 0.380), stroke (2.3% vs 2.5%, p = 0.917), major vascular complications (0.8% vs 2.2%, p = 0.268), composite bleeding complications (4.6% vs 6.4%, p = 0.647), requirement for permanent pacemaker (14.6% vs 12.9%, p = 0.426), postoperative hospital length of stay (3.3 ± 3.4 vs 3.1 ± 3.3 days, p = 0.467), or direct hospital costs ($52,899 ± 9,560 vs $50,464 ± 10,997, p = 0.230). Similarly, at 1-year, patients who underwent TC versus patients who underwent TF did not differ with respect to all-cause mortality (7.6% vs 6.4%, p = 0.659), hospital readmission (20.0% vs 23.9%, p = 0.635), or quality of life as measured by the Kansas City Cardiomyopathy Questionnaire score (84.0 ± 17.1 vs 88.4 ± 13.9, p = 0.062). Patients who underwent TC and TF did not differ with respect to in-hospital complications, length of hospital stay, and direct hospital costs, as well as 1-year mortality, readmission, and quality of life. These data add to ongoing support for the TC approach as the optimal alternative access for patients with transcatheter aortic valve replacement deferred from a transfemoral approach.

OBJECTIVE: The goal of this study was to assess the social determinants that influence access and outcomes for pediatric neurosurgical care for patients with Chiari malformation type I (CM-I) and syringomyelia (SM). METHODS: The authors used retro- and prospective components of the Park-Reeves Syringomyelia Research Consortium database to identify pediatric patients with CM-I and SM who received surgical treatment and had at least 1 year of follow-up data. Race, ethnicity, and insurance status were used as comparators for preoperative, treatment, and postoperative characteristics and outcomes. RESULTS: A total of 637 patients met inclusion criteria, and race or ethnicity data were available for 603 (94.7%) patients. A total of 463 (76.8%) were non-Hispanic White (NHW) and 140 (23.2%) were non-White. The non-White patients were older at diagnosis (p = 0.002) and were more likely to have an individualized education plan (p < 0.01). More non-White than NHW patients presented with cerebellar and cranial nerve deficits (i.e., gait ataxia [p = 0.028], nystagmus [p = 0.002], dysconjugate gaze [p = 0.03], hearing loss [p = 0.003], gait instability [p = 0.003], tremor [p = 0.021], or dysmetria [p < 0.001]). Non-White patients had higher rates of skull malformation (p = 0.004), platybasia (p = 0.002), and basilar invagination (p = 0.036). Non-White patients were more likely to be treated at low-volume centers than at high-volume centers (38.7% vs 15.2%; p < 0.01). Non-White patients were older at the time of surgery (p = 0.001) and had longer operative times (p < 0.001), higher estimated blood loss (p < 0.001), and a longer hospital stay (p = 0.04). There were no major group differences in terms of treatments performed or complications. The majority of subjects used private insurance (440, 71.5%), whereas 175 (28.5%) were using Medicaid or self-pay. Private insurance was used in 42.2% of non-White patients compared to 79.8% of NHW patients (p < 0.01). There were no major differences in presentation, treatment, or outcome between insurance groups. In multivariate modeling, non-White patients were more likely to present at an older age after controlling for sex and insurance status (p < 0.01). Non-White and male patients had a longer duration of symptoms before reaching diagnosis (p = 0.033 and 0.004, respectively). CONCLUSIONS: Socioeconomic and demographic factors appear to influence the presentation and management of patients with CM-I and SM. Race is associated with age and timing of diagnosis as well as operating room time, estimated blood loss, and length of hospital stay. This exploration of socioeconomic and demographic barriers to care will be useful in understanding how to improve access to pediatric neurosurgical care for patients with CM-I and SM.
RESUMO
The case of a 44-year-old female with multiple embolic cerebellar infarcts associated with a "high risk" patent foramen ovale (PFO) is presented. This article reviews current management of PFO in association with cryptogenic stroke in light of the results of three recent randomized controlled trials and two meta-analyses of observational data. The article will also discuss circumstances which merit consideration for closure despite the negative trial data, and will review our management strategy for closure in this patient with a nickel allergy that precluded the use of the most commonly used PFO closure device.

OPINION STATEMENT: Ever since the observation was made linking a higher prevalence of a patent foramen ovale (PFO) in younger individuals with cryptogenic stroke (CS), there has been a vigorous debate as to the role the PFO plays and a search for the optimal management strategy to prevent recurrent CS. Data from observational studies from the past two decades have demonstrated the superiority of percutaneous device closure over medical therapy. The recent publication of three randomized controlled trials (RCTs), which failed to demonstrate the superiority of percutaneous closure has reignited the controversy as to how best treat these patients. In this article, we will review the contemporary literature from the past three years including the results from new meta-analyses of medical therapy and device closure. In addition, we will review the three published randomized control trials to date (ie, CLOSURE I, the PC trial, and RESPECT) along with a meta-analysis of their results. While on primary intention-to-treat analysis, the three RCTs failed to demonstrate a superiority of percutaneous PFO closure vs medical therapy, a closer look at the data seems to suggest a trend toward benefit. We come to the conclusion that the issue of optimal treatment of PFO in patients with CS is far from settled and is unlikely to be a "one size fits all" approach due to the heterogeneity of this condition. In our opinion, based on the entirety of available data, both observational and randomized, there is likely a role for percutaneous device closure in select patients with CS in whom a PFO is the likely cause of their first stroke and will remain a significant risk for recurrent neurologic events. The article will go on to review current indications for atrial septal defect (ASD) closure and will highlight safety, efficacy and caveats regarding this technique.
RESUMO
The authors report the case of a 70-year-old man with metastatic colon cancer and no known history of coronary disease or major risk factors who developed coronary vasospasm after the initiation of capecitabine (Xeloda). Although coronary vasospasm has been associated with another older fluoropyrimidine compound, 5-fluorouracil, this is the first reported occurrence with this relatively newer cancer drug.

Hypertrophic cardiomyopathy (HCM) is a genetically determined, primary myocardial disease associated with an increased risk for sudden cardiac death during physical exertion. In the United States, HCM is the most frequent cause of exertion-related sudden cardiac death (SCD). Current recommendations provided by the 26th Bethesda Conference entitled Recommendations for Determining Eligibility for Competition in Athletes with Cardiovascular Abnormalities restrict participation for patients with HCM to sports requiring low levels of dynamic and isometric exertion. Such recommendations are prudent given the association of the disease with disastrous cardiovascular consequences. Nevertheless, because the prognosis of HCM and its risk of sudden death is typified by great variability among patients, these recommendations may be overly restrictive for many patients with this disease, and it is possible that a subset of low-risk patients can be identified who may continue to engage in more vigorous exercise activities. This article presents our current understanding and approach to evaluating and advising athletes with HCM.
