Abstract
PURPOSE Although esophagectomy remains the preferred treatment for esophageal cancer, it is still associated with a number of complications, including post-operative venous thromboembolism (VTE). The aim of this study was to summarize the reported incidence of VTE after esophagectomy, its risk factors, and prevention strategies. METHODS We conducted a systematic search of the literature in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS Fourteen studies met our inclusion criteria and were selected in the present review. Overall, we identified 9768 patients who underwent esophagectomy, with a post-operative VTE rate of 4% (440 patients). The reported risk factors for VTE included advanced age, American Society of Anesthesiologists (ASA) class III or IV, a history of cardiovascular or pulmonary disease, and the implementation of preoperative chemo-radiotherapy. Postoperative acute respiratory distress syndrome was also associated with VTE. No universally applied prevention strategies for VTE after esophagectomy were identified in the literature. CONCLUSIONS Despite advances in perioperative care, VTE after esophagectomy still represents a source of morbidity for about 4% of patients. Low molecular weight heparin is suggested as the routine standard prophylactic regimen after esophageal cancer surgery.

Abstract
Peripheral artery disease (PAD) affects 3%-10% of the Western population and if remains untreated can have devastating consequences to patients and their families. This review article analyzes how healthy dietary habits can decrease PAD rates when applied in the general population. The aim is to focus on dietary, nutritional and weight management interventions in patients with established PAD. Most adults with PAD are overweight or obese, while three out of four patients are characterized by deficiencies in vitamins and minerals. Weight loss interventions when needed and specialized dietary plans should be routinely recommended in patients with PAD. Appropriate nutritional support is of paramount importance in patients with advanced stages of PAD (critical limb ischemia).

Abstract
BACKGROUND-OBJECTIVE Prior studies have suggested a higher prevalence of simple renal cysts (SRC) among patients with aortic disease, including abdominal aortic aneurysms (AAA). Thus, the aim of this study was to systematically review all currently available literature and investigate whether patients with AAA are more likely to have SRC. METHODS This study was performed according to the PRISMA guidelines. A meta-analysis was conducted with the use of random effects modeling and the I-square was used to assess heterogeneity. Odds ratios (OR) and the corresponding 95% confidence intervals (CI) were synthesized to compare the prevalence of several patients' characteristics between AAA vs. no-AAA cases. RESULTS Eleven retrospective studies, 9 comparative (AAA vs. no-AAA groups) and 3 single-arm (AAA group), were included in this meta-analysis, enrolling patients (AAA: N = 2,297 vs. no-AAA: N = 35,873) who underwent computed tomography angiography as part of screening or preoperative evaluation for reasons other than AAA. The cumulative incidence of SRC among patients with AAA and no-AAA was 55% (95% CI: 49%-61%) and 32% (95% CI: 22%-42%) respectively, with a statistically higher odds of SRC among patients with AAA (OR: 3.02; 95% CI: 2.01-4.56; P< 0.001). The difference in SRC prevalence remained statistically significant in a sensitivity analysis, after excluding the study with the largest sample size (OR: 2.71; 95% CI: 1.91-3.84; P< 0.001). CONCLUSIONS Our meta-analysis demonstrated a 3-fold increased prevalence of SRC in patients with AAA compared to no-AAA cases, indicating that the pathogenic processes underlying SRC and AAA could share a common pathophysiologic mechanism. Thus, patients with SRC could be considered at high risk for AAA formation, potentially warranting an earlier AAA screening.

Abstract
INTRODUCTION Red cell distribution (RDW) is associated with atrial fibrillation (AF) incidence. However, its relationship with precursors of AF has not been established. We aim to investigate if association exists between RDW and negative P wave amplitude in V1, a marker of left atrial abnormality. METHODS NHANES III is a complex, multistage, clustered design survey of noninstitutionalized United States population between 1988-94. A Sample of 6403 individuals was extracted after excluding missing demographic, laboratory, anthropometric and ECG data and major ECG abnormalities. Variables were selected and univariate analysis was done first with a level of significance at P<0.01 (99% confidence). All the significant variables were included in a multivariate linear regression model. RESULTS 53.58% of subjects were female. Racial distribution was caucasian 50.2%, hispanic 23.9% and african american 21.7%. Age, PR interval, heart rate, systolic blood pressure, red cell distribution width, glycated hemoglobin, serum cholesterol, serum ferritin, and body mass index showed a significant correlation with negative P wave amplitude in V1 (P<0.001). After including all these variables in a multivariate regression model, only age, body mass index, systolic blood pressure, PR interval, heart rate and red cell distribution width had a P≤0.001. CONCLUSIONS Increased RDW is independently associated with negative P wave amplitude in V1 after correcting for other cardiovascular risk factors. Further studies are required to analyze the reason for this correlation.

Abstract
Coronavirus disease 2019 (COVID-19) does not only affect the respiratory system but appears to be a systemic disease. Venous thromboembolism is a common manifestation in hospitalized patients with COVID-19 with a reported incidence that is significantly higher compared to other acute viral infections. The pathophysiology mechanisms have not been fully explored and autopsy studies might enhance our understanding on this topic. Microthrombi formation occurs mainly in the pulmonary vasculature but can also occur in other organs. The high inflammatory burden related to COVID-19 seems to be associated with the coexisting coagulopathy. Concomitant manifestations of COVID-19, such as severe pneumonia, which has similar clinical presentation with pulmonary embolism (PE), and barriers related to strict isolation protocols are the two main reasons why PE diagnosis might be more challenging in patients with COVID-19. Medical societies have published guidance reports suggesting the administration of prophylactic anticoagulant therapy in hospitalized patients with COVID-19, but several questions regarding the optimal acute and long-term treatment of these patients remain unanswered.

Abstract
Ventricular assist devices (VADs) have played an important role in altering the natural history of end-stage heart failure. Low-grade hemolysis has been traditionally described in patients with VADs, indicating effective device functionality. However, clinically significant hemolysis could be crucial in terms of prognosis, calling for prompt therapeutic actions. The absence of solid and widely approved diagnostic criteria for clinically significant hemolysis, render the utilization of hemolysis laboratory markers challenging. Hemolysis incidence varies (5%-18%) depending on definition and among different VAD generations, being slightly higher in continuous-flow devices than in pulsatile devices. Increased shear stress of red blood cells and underlying device thrombosis appear to be the main pathogenetic pathways. No certain algorithm is available for the management of hemolysis in patients with VADs, while close clinical and laboratory monitoring remains the cornerstone of management. Imaging examinations such as echocardiography ramp test or computed tomography scan could play a role in revealing the underlying cause. Treatment should be strictly personalized, including either pharmacological (antithrombotic treatment) or surgical interventions.

Abstract
Importance Echocardiographic left ventricular global longitudinal strain (GLS) detects early subclinical ventricular dysfunction and can be used in patients receiving potentially cardiotoxic chemotherapy. A meta-analysis of the prognostic value of GLS for cancer therapy-related cardiac dysfunction (CTRCD) has not been performed, to our knowledge. Objective To explore the prognostic value of GLS for the prediction of CTRCD. Data Sources Systematic search of the MEDLINE, Embase, Scopus, and the Cochrane Library databases from database inception to June 1, 2018. Study Selection Cohort studies assessing the prognostic or discriminatory performance of GLS before or during chemotherapy for subsequent CTRCD. Data Extraction and Synthesis Random-effects meta-analysis and hierarchical summary receiver operating characteristic curves (HSROCs) were used to summarize the prognostic and discriminatory performance of different GLS indices. Publication bias was assessed using the Egger test, and meta-regression was performed to assess sources of heterogeneity. Main Outcomes and Measures The primary outcome was CTRCD, defined as a clinically significant change in left ventricular ejection fraction with or without new-onset heart failure symptoms. Results Analysis included 21 studies comprising 1782 patients with cancer, including breast cancer, hematologic malignancies, or sarcomas, treated with anthracyclines with or without trastuzumab. The incidence of CTRCD ranged from 9.3% to 43.8% over a mean follow-up of 4.2 to 23.0 months (pooled incidence, 21.0%). For active treatment absolute GLS (9 studies), the high-risk cutoff values ranged from -21.0% to -13.8%, with worse GLS associated with a higher CTRCD risk (odds ratio, 12.27; 95% CI, 7.73-19.47; area under the HSROC, 0.86; 95% CI, 0.83-0.89). For relative changes vs a baseline value (9 studies), cutoff values ranged from 2.3% to 15.9%, with a greater decrease linked to a 16-fold higher risk of CTRCD (odds ratio, 15.82; 95% CI, 5.84-42.85; area under the HSROC, 0.86; 95% CI, 0.83-0.89). Both indices showed significant publication bias. Meta-regression identified differences in sample size and CTRCD definition but not GLS cutoff value as significant sources of interstudy heterogeneity. Conclusions and Relevance In this meta-analysis, measurement of GLS after initiation of potentially cardiotoxic chemotherapy with anthracyclines with or without trastuzumab had good prognostic performance for subsequent CTRCD. However, risk of bias in the original studies, publication bias, and limited data on the incremental value of GLS and its optimal cutoff values highlight the need for larger prospective multicenter studies.

Abstract
BACKGROUND & AIMS New York is the current epicenter of Coronavirus disease 2019 (COVID-19) pandemic. The underrepresented minorities, where the prevalence of obesity is higher, appear to be affected disproportionately. Our objectives were to assess the characteristics and early outcomes of patients hospitalized with COVID-19 in the Bronx and investigate whether obesity is associated with worse outcomes independently from age, gender and other comorbidities. METHODS This retrospective study included the first 200 patients admitted to a tertiary medical center with COVID-19. The electronic medical records were reviewed at least three weeks after admission. The primary endpoint was in-hospital mortality. RESULTS 200 patients were included (female sex: 102, African American: 102). The median BMI was 30 kg/m2. The median age was 64 years. Hypertension (76%), hyperlipidemia (46.2%), and diabetes (39.5%) were the three most common comorbidities. Fever (86%), cough (76.5%), and dyspnea (68%) were the three most common symptoms. 24% died during hospitalization (BMI < 25 kg/m2: 31.6%, BMI 25-34 kg/m2: 17.2%, BMI ≥ 35 kg/m2: 34.8%, p = 0.03). Increasing age (analyzed in quartiles), male sex, BMI ≥ 35 kg/m2 (reference: BMI 25-34 kg/m2), heart failure, CAD, and CKD or ESRD were found to have a significant univariate association with mortality. The multivariate analysis demonstrated that BMI ≥ 35 kg/m2 (reference: BMI 25-34 kg/m2, OR: 3.78; 95% CI: 1.45-9.83; p = 0.006), male sex (OR: 2.74; 95% CI: 1.25-5.98; p = 0.011) and increasing age (analyzed in quartiles, OR: 1.73; 95% CI: 1.13-2.63; p = 0.011) were independently associated with higher in-hospital mortality. Similarly, age, male sex, BMI ≥ 35 kg/m2 and current or prior smoking were significant predictors for increasing oxygenation requirements in the multivariate analysis, while male sex, age and BMI ≥ 35 kg/m2 were significant predictors in the multivariate analysis for the outcome of intubation. CONCLUSIONS In this cohort of hospitalized patients with COVID-19 in a minority-predominant population, severe obesity, increasing age, and male sex were independently associated with higher in-hospital mortality and in general worse in-hospital outcomes.

Abstract
BACKGROUND Coronary artery disease requiring coronary artery bypass graft (CABG) frequently coexists with critical carotid stenosis. The most optimized strategy for treating concomitant carotid and coronary artery disease remains debatable. OBJECTIVE The aim of this meta-analysis was to compare synchronous CAS and CABG versus staged CAS and CABG for patients with concomitant coronary artery disease and carotid artery stenosis in terms of peri-operative (30-day) and long-term clinical outcomes. METHODS This study was performed according to the PRISMA guidelines. Eligible studies were identified through a search of PubMed, Scopus and Cochrane database until December 2019. A meta-analysis was conducted with the use of a random effects model. The I-square statistic was used to assess heterogeneity. RESULTS Four studies comprising 357 patients were included in this meta-analysis. Patients who were treated with the synchronous approach had a statistically significant higher risk for peri-operative stoke (OR: 3.71; 95% CI: 1.00-13.69; I2 = 0%) compared tο the staged group. Peri-operative mortality (OR: 4.50; 95% CI: 0.88-23.01; I2 = 0%), myocardial infarction (MI) (OR: 1.54; 95% CI: 0.18- 13.09; I2 = 0%), postoperative bleeding (OR: 0.27;95% CI: 0.02-3.12; I2 = 0%), transient ischemic attacks (TIA) (OR: 0.60; 95% CI: 0.04- 9.20; I2 = 0.0%), acute kidney injury (AKI) (OR: 0.34; 95% CI: 0.03-4.03; I2 = 0.0%) and atrial fibrillation rates (OR:0.27; 95% CI: 0.02-3.12; I2 = 0.0%) were similar between the two groups. Synchronous CAS-CABG and staged CAS followed by CABG were associated with similar rates of late mortality (OR: 3.75; 95% CI: 0.50-27.94; I2 = 0.0%), MI (OR: 0.33; 95% CI: 0.01-12.03; I2 = 0.0%) and stroke (OR:3.58; 95% CI:0.84-15.20; I2 = 0.0%) after a mean follow-up of 47 months. CONCLUSION The simultaneous approach was associated with an increased risk of 30-day stroke compared to staged CAS and CABG. However, no statistically significant difference was found in long-term results of mortality, MI and stroke between the two approaches. Future studies are warranted to validate our results.

Abstract
The association between active smoking and wound healing in critical limb ischemia (CLI) is unknown. Our objective was to examine in a retrospective cohort study whether active smoking is associated with higher incomplete wound healing rates in patients with CLI undergoing endovascular interventions. Smoking status was assessed at the time of the intervention, comparing active to no active smoking, and also during follow-up visits at 6 and 9 months. Cox regression analysis was conducted to compare the incomplete wound healing rates of the two groups during follow-up. A total of 264 patients (active smokers: n = 41) were included. Active smoking was associated with higher rates of incomplete wound healing in the 6-month univariate Cox regression analysis (hazard ratio (HR) for incomplete wound healing: 4.54; 95% CI: 1.41-14.28; p = 0.012). The 6-month Kaplan-Meier (KM) estimates for incomplete wound healing were 91.1% for the active smoking group versus 66% for the non-current smoking group. Active smoking was also associated with higher rates of incomplete wound healing in the 9-month univariable (HR for incomplete wound healing: 2.32; 95% CI: 1.11-4.76; p = 0.026) and multivariable analysis (HR for incomplete wound healing: 9.09; 95% CI: 1.06-100.0; p = 0.044). The 9-month KM estimates for incomplete wound healing were 75% in the active smoking group versus 54% in the non-active smoking group. In conclusion, active smoking status at the time of intervention in patients with CLI is associated with higher rates of incomplete wound healing during both 6- and 9-month follow-up.

Abstract
Purpose: To examine whether the combination of orbital atherectomy (OA) and drug-coated balloons (DCB) can lead to superior procedural and 2-year outcomes compared with DCB only in heavily calcified femoropopliteal (FP) lesions. Materials and Methods: A retrospective chart review was conducted to identify patients treated with DCB only or OA+DCB for de novo FP lesions at a single center over a 4-year period (2014–2017). In the observation period, 113 patients met the inclusion criteria: 63 treated with DCB only (mean age 69.0±8.6 years; 62 men) vs 50 treated with OA+DCB (mean age 70.3±7.1 years; 48 men). The OA+DCB group had higher calcification rates (78% with severe calcification vs 37% in the DCB only group). Propensity score matching (PSM) was used to adjust for baseline differences between the 2 groups. Cox regression analysis was used to compare the follow-up outcomes between lesions treated with OA+DCB vs DCB only. Results: No difference in procedural complications or success was found. After PSM adjustment, the OA+DCB group was associated with lower bailout stenting rates (39.4% vs 66.7% in the DCB only group; p=0.026). The 2 groups had similar long-term outcomes, although the OA+DCB arm had a trend toward reduced TLR rates that did not reach statistical significance. The Kaplan-Meier estimates for 2-year freedom from TLR were 76.1% for the OA+DCB group vs 55.5% for the DCB only group (p=0.109). Conclusion: OA+DCB is a safe and effective combination for the treatment of calcified FP lesions. The combined therapy decreased the bailout stenting rates in the adjusted analysis. Larger cohorts and randomized trials are needed to examine OA efficacy in FP lesions.

Abstract
Background and Purpose- Atrial fibrillation (AF) is the most common chronic arrhythmia. Dementia and cognitive impairment (CI) are major burdens to public health. The prevalence of all 3 entities is projected to increase due to population aging. Previous reports have linked AF with a higher risk of CI and dementia in patients without prior stroke. Stroke is known to increase the risk for dementia and CI. It is unclear if AF in patients with history of stroke can further increase the risk for dementia or CI. Our purpose was to evaluate the impact of AF on risk for dementia or CI among patients with history of stroke. Methods- Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines were followed. Pubmed, Scopus, and Cochrane central were searched. The outcomes of interest were dementia, CI, and the composite end point of dementia or CI. A random-effect model meta-analysis was performed. Meta-regression analysis was also performed. Publication bias was assessed with the Egger test and with funnel plots. Results- Fourteen studies and 14 360 patients (1363 with AF) were included in the meta-analysis. In the meta-analysis of adjusted odds ratio, AF was associated with increased risk of CI (odds ratio, 1.60 [95% CI, 1.20-2.14]), dementia (odds ratio, 3.11 [95% CI, 2.05-4.73]), and the composite end point of CI or dementia (odds ratio, 2.26 [95% CI, 1.61-3.19]). The heterogeneity for the composite end point of dementia or CI was moderate (adjusted analysis). The heterogeneity for the analysis of the end point of CI only was substantial in the unadjusted analysis and moderate in the adjusted analysis. The heterogeneity for the end point of dementia only was moderate in the unadjusted analysis and zero in the adjusted analysis. Conclusions- Our results indicate that an association between AF and CI or dementia is patients with prior strokes is possible given the persistent positive associations we noticed in the unadjusted and adjusted analyses. The heterogeneity levels limit the certainty of our findings.

Abstract
More than 200 million people worldwide have peripheral artery disease (PAD) or its most severe manifestation, critical limb ischemia (CLI). While endovascular treatment has become first line therapy in most cases, a number of challenges remain for optimal treatment of femoropopliteal (FP) or infrapopliteal (IP) disease, especially when these lesions are severely calcified, chronic total occlusions (CTOs) or in-stent restenosis (ISR). Continued evolution of technologies has significantly improved the outcomes for endovascular treatment. A number of new devices are in the pipeline right now, including new paclitaxel eluting stents and balloons, intravascular lithotripsy to treat severely calcified lesions, adventitial delivery of anti-restenotic agents to limit restenosis rates, and percutaneous femoro-popliteal bypass.

Abstract
Purpose: To investigate the prognostic role of contralateral carotid artery occlusion (CCO) in perioperative outcomes of patients undergoing carotid artery endarterectomy (CEA) vs carotid artery stenting (CAS). Materials and Methods: The PubMed, Scopus, and Cochrane databases were searched up to September 2018 to identify observational or randomized studies that compared outcomes of carotid revascularization in patients with vs without CCO. Forty-three studies (46 arms) comprising 96,658 patients were selected (75,857 CEA and 20,801 CAS). The CCO group included 9258 patients. Heterogeneity was assessed with the Higgins I2 test. I2>75% indicated significant heterogeneity. A random effects model was used to account for heterogeneity among studies. The results were reported as the odds ratios (ORs) with the 95% confidence intervals (CIs). Meta-regression analysis examined potential confounders. Publication bias was quantified by the Egger method. Results: Carotid revascularization in patients with CCO was associated with an increased risk of 30-day mortality (OR 1.75, 95% CI 1.38 to 2.23, p<0.001; I2=0%), stroke (OR 1.77, 95% CI 1.41 to 2.22, p<0.001; I2=46%), transient ischemic attack (TIA) (OR 2.10, 95% CI 1.34 to 3.27, p=0.001; I2=15%), and the composite endpoint of stroke/death (OR 1.78, 95% CI 1.54 to 2.05, p<0.001; I2=0%). No difference was noted in the risk of perioperative myocardial infarction (OR 0.81, 95% CI 0.50 to 1.31; p=0.388; I2=0%). Subgroup analysis demonstrated that CEA in patients with CCO was associated with an increased risk of stroke (OR 2.07, 95% CI 1.72 to 2.49, p<0.001; I2=14%), death (OR 1.80, 95% CI 1.55 to 2.10, p<0.001; I2=0%), TIA (OR 2.18, 95% CI 1.38 to 3.45, p<0.001; I2=13%), and stroke/death (OR 1.80, 95% CI 1.55 to 2.10, p<0.001; I2=0%), whereas CCO patients who were treated with CAS were at an increased risk for death (OR 1.65, 95% CI 1.07 to 2.60, p=0.023; I2=0%) but not stroke (OR 0.94, 95% CI 0.61 to 1.47; p=0.080; I2=31%) or TIA (OR 1.18, 95% CI 0.18 to 7.55; p=0.861; I2=43%). The meta-regression analysis did not find any significant association for any of the outcomes, and there was no evidence of publication bias. Conclusion: Carotid revascularization outcomes are adversely affected by the presence of CCO. Patients with CCO have a significantly higher risk of periprocedural stroke, death, and TIA. CEA in patients with CCO is associated with an increased risk of perioperative stroke, death, TIA, and death/stroke, while CAS in the presence of a CCO is associated with an increased risk of periprocedural death but not stroke or TIA.

Abstract
OBJECTIVES The aim of this systematic review was to explore the prognostic value of late gadolinium enhancement (LGE) in patients with aortic stenosis (AS). BACKGROUND Myocardial fibrosis is a common feature of many cardiac diseases. Cardiac magnetic resonance (CMR) has the ability to noninvasively detect regional fibrosis by using the LGE technique. Several studies have explored whether LGE is associated with adverse outcome in patients with AS. METHODS Electronic databases were searched to identify studies investigating the ability of LGE to predict all-cause mortality in patients with AS. A random effects model meta-analysis was conducted. Heterogeneity was assessed with the I2 statistic. RESULTS Six studies comprising 1,151 patients met our inclusion criteria. LGE was present in 49.1% of patients with AS. In the pooled analysis, LGE was found to be a strong univariate predictor of all-cause mortality (pooled unadjusted odds ratio: 2.56; 95% confidence interval: 1.83 to 3.57; I2 = 0%). Four of the included studies reported adjusted hazard ratios for mortality. LGE was independently associated with mortality, even after adjusting for baseline characteristics (pooled adjusted hazard ratio: 2.50; 95% confidence interval: 1.64 to 3.83; I2 = 0%). CONCLUSIONS Fibrosis on LGE-CMR is a powerful predictor of all-cause mortality in patients with AS and may serve as a novel marker for risk stratification. Future studies should explore whether LGE-CMR can also be used to optimize timing of AS-related interventions.

Abstract
High-intensity statins are recommended for patients with peripheral artery disease (PAD). Critical limb ischemia (CLI) is the most advanced presentation of PAD. The benefit of statins in the CLI population is unclear based on the existent studies. Our objective was to perform a systematic review and meta-analysis regarding the efficacy of statin therapy in patients with CLI. PRISMA guidelines were followed. PubMed, EMBASE, and Cochrane CENTRAL databases were reviewed up to April 30, 2019. The primary outcomes included amputation rates and all-cause mortality. Secondary outcomes included primary patency rates, amputation-free survival and major adverse cardiac or cerebrovascular events (MACCE). Risk of bias was assessed with the Robins-I tool for observational studies. A random-effects model meta-analysis was performed. Heterogeneity was assessed with I2. Funnel plots and Egger’s test were used to assess publication bias. Nineteen studies including 26,985 patients with CLI were included in this systematic review. Among patients with known data on statin status, 12,292 (49.6%) were on statins versus 12,513 (50.4%) not on statins. Patients treated with statins were 25% less likely to undergo amputation (HR 0.75; 95% CI: 0.59–0.95; I2 = 79%) and 38% less likely to have a fatal event (HR 0.62; 95% CI: 0.52–0.75; I2 = 41.2%). Statin therapy was also associated with increased overall patency rates and lower incidence of MACCE. There was substantial heterogeneity in the analysis for amputation and amputation-free survival (I2 > 70%). In conclusion, statins are associated with decreased risk for amputation, mortality, and MACCE, as well as increased overall patency rates among patients with CLI. Future studies should assess whether other lipid-lowering medications in addition to high-intensity statins can further improve outcomes among patients with CLI.

Abstract
PURPOSE OF THE REVIEW Peripheral artery disease (PAD) affects close to 200 million people worldwide. Claudication is the most common presenting symptom for patients with PAD. This review summarizes the current diagnostic and treatment options for patients with claudication. Comprehensive history and physical examination in order to differentiate between claudication secondary to vascular disease vs. neurogenic causes is paramount for initial diagnosis. Ankle-brachial index is the most commonly used test for screening and diagnostic purposes. Treatment consists of four different approaches, which are best utilized in combination: non-pharmacological treatment for claudication improvement, pharmacological treatment for claudication improvement, pharmacological treatment for secondary risk reduction, and interventional treatment for claudication improvement. RECENT FINDINGS Cilostazol is the only Food and Drug Administration (FDA)-approved agent for symptomatic treatment of claudication. Supervised exercise programs provide the maximum benefit for claudication improvement, but home-based exercise programs are an alternative. High-intensity statins and an antiplatelet agent should be prescribed to all patients with PAD. Angiotensin-converting-enzyme inhibitors can provide additional risk reduction, especially in patients with diabetes or hypertension. Rivaroxaban of low dosage (2.5 mg twice daily) in combination with aspirin further decreases cardiovascular risk, but this reduction comes at the cost of higher bleeding risk. Peripheral artery disease (PAD) is a form of atherosclerotic disease that affects hundreds of millions of people worldwide-one of its most common manifestations is intermittent claudication (IC), which results from insufficient blood flow to meet the metabolic demands of an affected extremity. This paper reviews the current literature regarding the workup, diagnosis, diagnostic modalities, treatment options, and management of intermittent claudication.

Abstract
Non-vitamin K oral anticoagulants (NOACs), including dabigatran, rivaroxaban, apixaban, and edoxaban, are increasingly used for thromboembolism prevention. Contrary to older anticoagulants, such as coumadin, when antidotes existed and were broadly used in cases of emergent surgery and bleeding, antidotes for NOACs have not been developed until recently. Moreover, the monitoring of NOAC's anticoagulant effect varies across different hospital settings and the absence of a single test that can accurately predict the degree of anticoagulation achieved increases the uncertainty. These uncertainties often result in management dilemmas for clinicians when patients who are on NOACs need a reversal of anticoagulation. Until recently, available antidotes for NOACs included only prothrombin complex concentrate (PCC), activated prothrombin complex concentrate (aPCC) and recombinant activated factor VII and the less optimal fresh frozen plasma (FFP). Recently though, novel antidotes for NOACs have been developed, including idarucizumab, which is a monoclonal antibody fragment that binds dabigatran, and andexanet alfa, a modified decoy form of the activated factor X (FXa) that binds FXa inhibitors and AT III. Another option, ciraparantag, which is a small molecule that binds to heparin, thrombin inhibitors and FXa inhibitors, is still in phase I development. In this review, we summarize the current evidence and present the available bypassing and novel reversal agents. Finally, we propose an algorithm for the management of patients who take NOACs and present to the emergency department with either trauma and active bleeding or need for emergent surgery.

Abstract
BACKGROUND Femoropopliteal (FP) artery in-stent restenosis (ISR) is associated with high rates of re-intervention and occlusion. The combined use of laser atherectomy (LA) with balloon angioplasty (BA) is superior to conventional balloon angioplasty (BA). Drug-coated balloons (DCBs) when combined with LA have provided additional efficacy for the treatment of FP-ISR. The aim of this study was to investigate the combination of DCB + LA with the recently approved Turbo-Power™ (Spectranetics Inc., Colorado Springs, CO, USA) LA device. METHODS This was a dual-center retrospective study enrolling 78 consecutive patients with Tosaka type II (n = 18) or III (n = 60) FP-ISR. The lesions were treated with either Turbo-Power™ LA followed by DCB (n = 27) or with other LA devices followed by plain BA (LA + BA; n = 51) from 2015 to 2017. A Cox regression analysis was performed to examine the association between the two groups in terms of target lesion revascularization (TLR) and occlusion rates over a follow up period of 12 months. Kaplan-Meier survival curves were estimated and compared with the log-rank test. RESULTS The overall procedural success was 90%. Eight periprocedural complications occurred without any difference between the two groups (Turbo-Power™ + DCB: 7.4% vs LA + BA: 11.8%, p = .7). The 12-month KM estimates for freedom from TLR were 90.9% in the Turbo-Power™ + DCB group vs 55.7% in the LA + BA group (p = .005). Among Toasaka III lesions, the 12 m-KM survival estimates for freedom from TLR were 88.9% in the Turbo-Power™ + DCB group vs 54.2% in the LA + BA group (p = .009). The 12 m-KM estimates for freedom from re-occlusion were 89.0% in the Turbo-Power™ + DCB group vs 58.9% in the LA + BA group (p = .070). CONCLUSIONS Turbo-Power™ laser atherectomy combined with DCB exerted synergistic mechanism of actions and improved 12-month TLR rates for the treatment of complex FP-ISR lesions.

Abstract
Residual aortic regurgitation (AR) is a major complication after transcatheter aortic valve implantation (TAVI). Although the echocardiographic assessment of post-TAVI AR remains challenging, cardiac magnetic resonance (CMR) allows direct quantification of AR. The aim of this study was to review the level of agreement between 2-dimensional transthoracic echocardiography (2D TTE) and CMR on grading the severity of AR after TAVI, and determine the accuracy of TTE in detecting moderate or severe AR. Electronic databases were searched in order to identify studies comparing 2D TTE to CMR for post-TAVI AR assessment. Kappa coefficient was used to determine the level of agreement between the 2 imaging modalities. CMR was used as the reference standard in order to assess the diagnostic accuracy of 2D TTE. Seven studies were included in this systematic review. Six studies reported a low correlation between 2D TTE and CMR (kappa coefficient ranging from -0.02 to 0.41), whereas one study showed good agreement with a kappa coefficient of 0.72. Given the heterogeneity in the included studies the diagnostic accuracy of TTE was evaluated by estimating the hierarchical summary receiver operator characteristic curve. The area under the curve for detection of moderate or severe AR with TTE was 0.83 (95% confidence interval 0.79 to 0.86). In conclusion, despite the reported significant disconcordance between TTE and CMR grading of AR, TTE has sufficient ability to discriminate moderate or severe AR from mild or none AR after TAVI in the clinical setting. CMR should be considered when TTE results are equivocal.

Abstract
BACKGROUND Management of iliac artery occlusive disease has changed dramatically over the past few decades. Secondary to advancement in endovascular technologies and techniques, percutaneous interventions have gradually replaced open surgical approaches even for the most difficult cases. In difficult to cross chronic total occlusions (CTO) of the iliac artery, subintimal angioplasty (SIA) with or without the use of re-entry devices (RED) offers a valuable alternative to intra-luminal crossing. OBJECTIVE To systematically review the literature for studies reporting procedural or short- and long-term clinical outcomes after the use of SIA, with or without RED use for iliac CTOs. METHODS PRISMA guidelines were followed. Literature search (PubMed, Cochrane CENTRAL and EMBASE) and data extraction were performed by two independent researchers. Quantitative synthesis of the reported outcomes was applied when possible. RESULTS Thirty studies met the inclusion criteria and were selected as eligible for this systematic review, with a total of 1002 patients (61.3% males) and 1112 lesions treated with SIA. RED were used in 21.9% of the lesions. Critical limb ischemia was the indication in 51.4%. The overall procedural success rates were 85.8% for SIA and 88.5% for RED. The complication rate ranged from 0 to 10% among different series, but overall it was similar among the two groups (6.9% in the RED group and 6.7% among the SIA group). One year primary patency rates were around 60% in the RED. In the SIA only arm, there was a large heterogeneity, with patency rates ranging from 51.7% to 96.8%. CONCLUSION SIA with or without RED use is a safe and effective treatment for the treatment of iliac artery CTOs. Future studies are needed to delineate whether intraluminal crossing or SIA is more effective for endovascular treatment of iliac CTOs.

Abstract
Purpose: To examine whether an antegrade or retrograde crossing strategy for treatment of iliac artery chronic total occlusions (CTOs) is associated with differences in procedural or midterm outcomes. Materials and Methods: A dual-center retrospective cohort study was conducted in 168 patients (mean age 66.4±10.6 years; 116 men) treated for CTOs in 110 common iliac arteries (CIA), 52 external iliac arteries (EIA), and 26 combined CIA/EIAs. Logistic regression models were developed to determine the association between crossing strategy and procedural complications, 1- and 3-year target lesion revascularization (TLR), and major adverse limb events (MALE). Results are presented as the odds ratio (OR) and 95% confidence interval (CI). Results: An initial antegrade strategy was more common for EIA CTOs (p<0.005), and an initial retrograde strategy was more often used in CIA (p<0.005) and combined CIA/EIA (p<0.005) CTOs. Crossover to an alternate approach was required in 27.6% of initial antegrade attempts and 9.6% of initial retrograde attempts. EIA CTOs were the most likely lesions to be treated successfully with the initial attempt (either strategy). In all, 123 (65.4%) lesions were successfully crossed with a final retrograde approach and 65 with a final antegrade approach. Overall target lesion success was high for both groups (95.1% vs 93.2%, p=0.456). Lesions treated with a final retrograde approach were shorter (75.3±34.9 vs 87.6±31.3 mm, p=0.005) and were more likely to be treated with a reentry device (34.2% vs 9.2%, p<0.001) and with balloon-expandable stents (39.2% vs 17.7%, p=0.005). The final antegrade approach was associated with a lower risk of target lesion complications (OR 0.07, 95% CI 0.01 to 0.81, p=0.034). The two crossing approaches were associated with similar estimates of 1- and 3-year TLR and MALE. Conclusion: A final antegrade approach was associated with lower rates for complications but the 2 approaches were similar in terms of lesion success, TLR, and MALE. The EIA CTOs were more likely to be treated with an antegrade approach and more likely to be crossed successfully with the initial approach irrespective of the crossing direction.

Abstract
PURPOSE To examine the safety profile of transcervical access (TCA) in comparison with the transfemoral approach (TFA) in carotid artery stenting. MATERIALS AND METHODS A systematic review and meta-analysis was performed according to current guidelines. Eleven eligible studies including 11,592 patients (10,736 in the TFA group and 856 in the TCA group) were identified through a search of the PubMed, Scopus, and Cochrane databases up to October 2018. A random effects model meta-analysis was conducted, and the I2 statistic was used to assess heterogeneity. Publication bias was assessed using funnel plots and quantified using the Egger method. RESULTS The TFA group had a statistically significantly higher risk of periprocedural (30-day) stroke compared with the TCA group (OR 1.98, 95% CI 1.08 to 3.63, p=0.027; I2=0%). Also, patients in the TFA group had a significantly higher risk of developing new ischemic lesions (OR 2.97, 95% CI 1.48 to 5.96, p=0.002; I2=0%) on diffusion-weighted magnetic resonance imaging (DW-MRI). No differences in terms of transient ischemic attack (OR 1.50, 95% CI 0.73 to 3.10, p=0.268; I2=5.9%), myocardial infarction (OR 0.64, 95% CI 0.30 to 1.35; p=0.242; I2=0%), local hematoma (OR 0.53, 95% CI 0.12 to 2.25, p=0.389; I2=0%), or mortality (OR 1.35, 95% CI 0.62 to 2.92, p=0.449; I2=0%) were identified between the groups. CONCLUSION TCA is associated with a significantly lower risk for periprocedural stroke and DW-MRI ischemic lesions compared with TFA. Other periprocedural outcomes were similar between the groups.

Abstract
Abstract
Background
Oesophagectomy is associated with high morbidity and mortality rates. New-onset atrial fibrillation (AF) is a frequent complication following oesophagectomy. Several studies have explored whether new-onset AF is associated with adverse events after oesophagectomy.
Methods
This review was performed according to PRISMA guidelines. Eligible studies were identified through a search of PubMed, Scopus and Cochrane CENTRAL databases up to 25 November 2018. A meta-analysis was conducted with the use of random-effects modelling. The I2 statistic was used to assess for heterogeneity.
Results
In total, 53 studies including 9087 patients were eligible for analysis. The overall incidence of postoperative AF was 16·5 per cent. Coronary artery disease and hypertension were associated with AF, whereas diabetes, smoking and chronic obstructive pulmonary disease were not. Patients with AF had a significantly higher risk of overall postoperative adverse events than those without fibrillation (odds ratio (OR) 5·50, 95 per cent c.i. 3·51 to 8·30), including 30-day mortality (OR 2·49, 1·70 to 3·64), anastomotic leak (OR 2·65, 1·53 to 4·59) and pneumonia (OR 3·42, 2·39 to 4·90).
Conclusion
Postoperative AF is frequently observed in patients undergoing oesophagectomy for cancer. It is associated with an increased risk of death and postoperative complications.

Abstract
Background Oral anticoagulation therapy was the mainstay of deep vein thrombosis treatment but recently, catheter-directed thrombolysis has emerged as an alternative. Objective To compare the efficacy and safety of the two strategies. Methods Medline, Embase and Cochrane CENTRAL were reviewed. Outcomes of interest included post-thrombotic syndrome, thromboembolic events, mortality, bleeding risk and iliofemoral patency. A random effects model meta-analysis was performed. Heterogeneity was assessed with I square. Results Four randomized controlled trials (RCTs) including 1005 patients met the inclusion criteria. Catheter-directed thrombolysis was more likely to prevent overall post-thrombotic syndrome compared to anticoagulation only (OR: 0.32; 95% CI: 0.12–0.85; I2=87.2%), and to lead to iliofemoral vein patency (OR: 2.7; 95% CI: 1.08–6.75; I2=55.3%) but no difference was noted in thromboembolic events (OR = 0.5; 95% CI: 0.08–3.02, I2=55.1%), bleeding and mortality rates. Conclusions Catheter-directed thrombolysis can decrease post-thrombotic syndrome rates and improve iliofemoral vein patency compared to anticoagulation when used for the treatment of deep vein thrombosis.

Abstract
AIM To present the experience of the upper Gastrointestinal Unit of the Surgical Department of National and Kapodistrian University of Athens in order to inform surgeons of the exact harms and benefits associated with their decisions concerning management of antiplatelet therapy. MATERIALS AND METHODS This was a single-center study of patients who underwent surgery for esophageal cancer and had concomitant coronary artery disease from 1/1/2005 to 31/7/2017. Patients were divided into two cohorts based on when their antiplatelet therapy was stopped (<7 vs. ≥7 days). Esophageal cancer was classified as esophageal only or as Siewert type I, II, or III based on tumor location at the gastroesophageal junction. A univariate logistic regression model was developed to assess the relationship between baseline variables and myocardial infraction, mortality, bleeding and stroke after the operation. For all tests, differences with a value of p<0.05 were considered significant. RESULTS During the study period, 135 esophagectomies were performed for esophageal cancer. Almost 17% of them had concomitant coronary artery disease medically managed with antiplatelet therapy. No difference was found in terms of myocardial infarction, stroke or severe bleeding events between patients that stopped antiplatelet therapy for more or less than 7 days before esophagectomy. CONCLUSION It is a reasonable approach to discontinue antiplatelet therapy for more than 7 days before surgery, especially in such a population of patients with esophageal cancer that require complex operations with high bleeding risk.

Abstract
BACKGROUND Results from studies investigating the effect of contralateral carotid occlusion (CCO) in patients with carotid artery stenosis undergoing carotid artery endarterectomy (CEA) or carotid artery stenting (CAS) are variable in the literature. We sought to determine whether CEA or CAS is the optimal revascularization approach for patients with CCO. METHODS This meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A random effects model meta-analysis was conducted, and the I2 statistic was used to assess for heterogeneity. Subgroup and sensitivity analyses were performed as needed. RESULTS Five retrospective observational cohort studies comprising 6346 patients were included. Patients in the CEA group had a significantly lower risk of 30-day periprocedural mortality (odds ratio, 0.46; 95% confidence interval, 0.30-0.71; I2 = 0%). However, no significant differences were identified in terms of stroke, myocardial infarction (MI), and major adverse cardiovascular events (MACEs) between the 2 groups. Subgroup analyses of symptomatic and asymptomatic patients did not yield significant differences for stroke, MI, and death. CONCLUSIONS Patients with CCO can safely undergo both CAS and CEA with similar risks of stroke, MI, and MACE. However, patients treated with CEA have a lower risk of 30-day periprocedural mortality. Future studies can help further clarify the ideal approach for these patients.

Abstract
PURPOSE To determine through meta-analysis whether administration of statins before carotid artery stenting (CAS) is associated with fewer periprocedural adverse events. METHODS All randomized and observational English-language studies of periprocedural statin administration prior to CAS that reported the outcomes of interest (stroke, transient ischemic attack, myocardial infarction, and death at 30 days) were included in a random-effects meta-analysis. The I2 statistic was used to assess heterogeneity. Meta-regression analysis was performed to determine whether an association of statin treatment with risk of outcome events was influenced by other trial-level baseline characteristics of statin-treated and untreated patients. RESULTS Eleven studies comprising 4088 patients were included. Patients who received statins prior to CAS had a significantly lower risk of stroke (OR 0.39, 95% CI 0.27 to 0.58, p<0.01; I2=0%) and death (OR 0.30, 95% CI 0.10 to 0.96, p=0.042; I2=0%). Statin use was not associated with a reduced risk of transient ischemic attack or myocardial infarction. In meta-regression analysis, other trial-level baseline characteristics had no significant influence on the association of statin treatment with death or stroke. CONCLUSION Statin therapy prior to CAS is associated with decreased risk of perioperative stroke and death without any effect on the rates of transient ischemic attack or myocardial infarction.

Abstract
Purpose:To compare periprocedural complications and in-stent restenosis rates associated with open- vs closed-cell stent designs used in carotid artery stenting (CAS). Methods: A systematic search was conducted to identify all randomized and observational studies published in English up to October 31, 2017, that compared open- vs closed-cell stent designs in CAS. Identified studies were included if they reported the following outcomes: stroke, transient ischemic attack (TIA), myocardial infarction (MI), hemodynamic depression, new ischemic lesions detected on imaging, and death within 30 days, as well as the incidence of in-stent restenosis. A random-effects model meta-analysis was employed. Model results are reported as the odds ratio (OR) and 95% confidence interval (CI). The I2 statistic was used to assess heterogeneity. Results: Thirty-three studies (2 randomized trials) comprising 20, 291 patients (mean age 71.3±3.0 years; 74.6% men) were included. Patients in the open-cell stent group had a statistically significant lower risk of restenosis ⩾40% (OR 0.42, 95% CI 0.19 to 0.92; I2=0%) and ⩾70% (OR 0.23, 95% CI 0.10 to 0.52; I2=0%) at a mean follow-up of 24 months. No statistically significant differences were identified for periprocedural stroke, TIA, new ischemic lesions, MI, hemodynamic depression, or death within 30 days after CAS. Sensitivity analysis of the 2 randomized controlled trials only did not point to any significant differences either. Conclusion: Use of open-cell stent design in CAS is associated with a decreased risk for restenosis when compared to the closed-cell stent, without significant differences in periprocedural outcomes.

Abstract
BACKGROUND Long-term childhood cancer survivors (CCS) are at increased risk of adverse cardiovascular events; however, there is a paucity of risk-stratification tools to identify those at higher-than-normal risk. SUBJECTS, MATERIALS, AND METHODS This was a population-based study using data from the Surveillance, Epidemiology, and End Results Program (1973-2013). Long-term CCS (age at diagnosis ≤19 years, survival ≥5 years) were followed up over a median time period of 12.3 (5-40.9) years. Independent predictors of cardiovascular mortality (CVM) were combined into a risk score, which was developed in a derivation set (n = 22,374), and validated in separate patient registries (n = 6,437). RESULTS In the derivation registries, older age at diagnosis (≥10 years vs. reference group of 1-5 years), male sex, non-white race, a history of lymphoma, and a history of radiation were independently associated with an increased risk of CVM among long-term CCS (p < .05). A risk score derived from this model (Childhood and Adolescence Cancer Survivor CardioVascular score [CHACS-CV], range: 0-8) showed good discrimination for CVM (Harrell's C-index [95% confidence interval (CI)]: 0.73 [0.68-0.78], p < .001) and identified a high-risk group (CHACS-CV ≥6), with cumulative CVM incidence over 30 years of 6.0% (95% CI: 4.3%-8.1%) versus 2.6% (95% CI: 1.8%-3.7%), and 0.7% (95% CI: 0.5%-1.0%) in the mid- (CHACS-CV = 4-5) and low-risk groups (CHACS-CV ≤3), respectively (plog-rank < .001). In the validation set, the respective cumulative incidence rates were 4.7%, 3.1%, and 0.8% (plog-rank < .001). CONCLUSION We propose a simple risk score that can be applied in everyday clinical practice to identify long-term CCS at increased cardiovascular risk, who may benefit from early cardiovascular screening, and risk-reduction strategies. IMPLICATIONS FOR PRACTICE Childhood cancer survivors (CCS) are known to be at increased cardiovascular risk. Currently available prognostic tools focus on treatment-related adverse events and late development of congestive heart failure, but there is no prognostic model to date to estimate the risk of cardiovascular mortality among long-term CCS. A simple clinical tool is proposed for cardiovascular risk stratification of long-term CCS based on easily obtainable information from their medical history. This scoring system may be used as a first-line screening tool to assist health care providers in identifying those who may benefit from closer follow-up and enable timely deployment of preventive strategies.

Abstract
With growing use of drug-coated balloons (DCB) for femoropopliteal (FP) artery interventions, there is limited information on rates of real-world adjunctive stent use and its association with short and long-term outcomes. We report on 225 DCB treated FP lesions in 224 patients from the Excellence in Peripheral Artery Disease (XLPAD) registry (NCT01904851) between 2014 and 2016. Cochran–Mantel–Haenszel and Wilcoxon rank sum statistics were used to compare stented (planned or ‘bail-out’) versus non-stented DCB treated lesions. Stents were implanted in 31% of FP DCB interventions. Among the 70 stents implanted, 46% were for ‘bail-out’ indications and 54% were planned. Lesions treated with stents were longer (mean 150 mm vs 100 mm; p < 0.001) and less likely to be in-stent restenosis lesions (10% vs 28%; p=0.003). Stenting was significantly more frequent in complex FP lesions, including chronic total occlusions (66% vs 34%; p < 0.001). For bail-out stenting, interwoven nitinol stents were the most common type (50%) followed by drug-eluting stents (34%) and bare-metal stents (22%). There were no differences in peri-procedural complication rates or 12-month target limb revascularization rates (18.6% vs 11.6%; p=0.162) or 12-month amputation rates (11.4% vs 11%; p=0.92) between lesions where adjunctive stenting was used versus lesions without adjunctive stenting, respectively. In conclusion, in a contemporary ‘real-world’ adjudicated multicenter US registry, adjunctive stenting was necessary in nearly a third of the lesions, primarily for the treatment of more complex FP lesions, with similar short and intermediate-term clinical outcomes compared with non-stented lesions.

Abstract
OBJECTIVE To examine the impact of re-entry device (RED) use on 1- and 5-year outcomes after endovascular treatment of common iliac artery (CIA) chronic total Occlusions (CTOs). BACKGROUND There are not enough data regarding the long-term safety and efficacy of RED. METHODS We performed a two-center retrospective study of 115 patients (140 lesions) undergoing CIA CTO endovascular intervention between 2006 and 2016. Baseline characteristics and long-term outcomes were described. A Cox proportional hazard model was developed to determine if REDs were associated with target lesion revascularization (TLR) or major adverse limb events (MALE) after 1 and 5 years. RESULTS Among 140 lesions, 43 (31%) required use of a RED. The mean age was 63.9 years and the majority (n = 80) of patients were male. An antegrade crossing approach and treatment of restenotic lesions were less common in the RED group (10% vs. 29%, P < .05 and 0% vs. 21%, P < .05, respectively). There were no significant differences in Rutherford class, pre-procedure ABI, or patient presentation. The procedural complication rates were similar between the two groups. The 1- and 5-year TLR rates for lesions treated with re-entry device vs. standard approaches were 11% vs. 9%; P = 0.8 and 29% vs. 29%; P = 0.9 respectively. The 1 and 5-year MALE rates for lesions treated with re-entry device were 5% vs. 6%; P = 0.8 and 11% vs. 11%; P = 0.9 respectively. CONCLUSIONS This retrospective analysis found that recanalization of CIA occlusions using a RED is safe and is associated with long-term clinical outcomes similar to that of standard crossing techniques.

Abstract
BACKGROUND Patients with history of cryptogenic stroke are more likely to have a patent foramen ovale (PFO) and should be managed with antithrombotic agents, while the alternative option is percutaneous closure of PFOs. Our aim was to perform a meta-analysis of randomized controlled trials (RCTs) comparing percutaneous closure vs. medical treatment for patients with PFO and prior cryptogenic stroke. METHODS Medline, Scopus and Cochrane databases were reviewed. A random-effect model meta-analysis was used and I-square was utilized to assess the heterogeneity. New ischemic stroke was defined as the primary endpoint. A sensitivity analysis was performed for Amplatzer device. Subgroup analyses were performed for different patient and PFO characteristics for the composite endpoints as defined by the included RCTs. RESULTS In total of 3440 patients were included in this meta-analysis. Closure devices were superior to medical therapy for prevention of recurrent ischemic strokes (HR = 0.29; CI: 0.02-0.56), but were associated with increased risk of new onset of atrial fibrillation (AF) and atrial flutter (RR = 4.67; CI: 2.22-9.81). However, in the sensitivity analysis for Amplatzer device, there was no difference between the two groups in new onset of atrial arrhythmias. Closure devices were superior across all different subgroups when compared to medical treatment with the exception of patients with a small shunt. CONCLUSION This meta-analysis shows that closure devices for patients with PFO and history of cryptogenic stroke can significantly decrease the risk of a new ischemic stroke. The use of Amplatzer device was not associated with increased risk of newly diagnosed atrial arrhythmias.
