Sex Disparities in Left Ventricular Assist Device Implantation: Delayed Presentation and Worse Right Heart Failure.

We explored whether women undergo continuous-flow left ventricular assist device (CF-LVAD) implantation in later stages of heart failure (HF) than men, evidenced by worse preoperative right HF (RHF). We also compared two propensity models with and without preoperative RHF to assess its effect on outcomes. INTERMACS was queried from July 2008 to December 2017. Propensity model 1 matched men and women on age ≥50 years, HF etiology, body surface area, INTERMACS class, comorbidities, device strategy, temporary mechanical circulatory support, and device type. Model 2 included these variables plus LV end-diastolic diameter, right atrial pressure/pulmonary capillary wedge pressure, pulmonary artery pulsatility index, and right ventricular ejection fraction. The primary outcome was all-cause mortality. Secondary outcomes comprise RHF, rehospitalization, renal dysfunction, stroke, and device malfunction. In model 1, characteristics were comparable between 3,195 women and 3,195 men, except women more often had preoperative RHF and postoperative right VAD support and had worse 1 year and overall survival. In model 2, after propensity matching for additional risk factors for preoperative RHF, 1,119 women and 1,119 men had comparable post-LVAD implant RVAD use and survival. These findings suggest that women present more often with biventricular failure and after implantation have higher RHF and mortality rates.

Leadless pacemaker with transcatheter aortic valve implantation: A single-center experience.

BACKGROUND: The safety and efficacy of leadless pacemakers (LP) in transcatheter aortic valve implant (TAVI) patients is not well known due to paucity of data. Herein, we compared outcomes between leadless pacemakers to traditional dual chamber pacemakers (DCP) following TAVI. METHODS: A single-center retrospective study was conducted, including a total of 27 patients with LP and 33 patients with DCP after TAVI between November 2013 and May 2021. We compared baseline demographics, pacemaker indications, complication rates, percent pacing, and ejection fractions. RESULTS: Leading indications for pacemaker implant were complete heart block (74% LP, 73% DCP) and high degree atrioventricular block (26% LP, 21% DCP). Twenty-two (82%) LP patients had devices implanted in the right ventricular septal-apex. Three (9%) DCP patients required rehospitalization for pocket related complications. Zero pacemaker-related mortality was observed in both groups. Frequency of ventricular pacing and ejection fraction was similar between LP and DCP groups. CONCLUSION: From this single-center retrospective study, LP implant was feasible following TAVI and was found to have comparable performance to DCPs. LPs may be a reasonable alternative in TAVI patients where single ventricular pacing is indicated. Larger studies are required to validate these findings.

Correlation between Echocardiographic Diastolic Parameters and Invasive Measurements of Left Ventricular Filling Pressure in Patients with Takotsubo Cardiomyopathy.

BACKGROUND: The extent of diastolic dysfunction is of clinical importance in the risk stratification and management of patients with Takotsubo cardiomyopathy (TC). Standard echocardiographic indices of diastolic dysfunction have robust predictive ability in assorted disease states, but have not been validated in TC. The aim of this study was to compare Doppler metrics of diastolic function against catheterization-measured filling pressures in TC. METHODS: Patients with TC who met inclusion and exclusion criteria were evaluated using echocardiography and catheterization performed within 24 hours. Both left ventricular (LV) end-diastolic pressure and LV pre-A diastolic pressure were obtained from catheterization tracings. The echocardiographic parameters for diastolic function were extracted using the American Society of Echocardiography recommendations and a previously validated regression equation for mean left atrial pressure (mLAP). RESULTS: A total of 51 patients with TC were included. Patients were predominantly women (72.5%), with a mean age of 58 ± 13 years and a mean ejection fraction of 24 ± 10 %. E/e' ratio (septal, average, and lateral) and calculated mLAP correlated positively with catheterization LV pre-A, with fair to moderate correlation (coefficient range, 0.38-0.44). The t-test mean difference between LV pre-A pressure and calculated mLAP was 0.77 ± 7.34 mm Hg (95% CI, ±14.68 mm Hg) suggesting inconsistent measures. mLAP also exhibited poor diagnostic ability to discriminate elevated LV pre-A diastolic pressure, with an area under the receiver operating characteristic curve of 0.69 (95% CI, 0.50-0.88). CONCLUSIONS: Commonly used echocardiographic parameters for diastolic function demonstrated less-than-optimal correlation, with poor sensitivity and specificity, compared with invasively measured LV end-diastolic pressure or LV pre-A wave diastolic pressure in patients with TC. Precise characterization of LV filling pressure in patients with TC using contemporary noninvasive echocardiographic parameters appears challenging. Invasive measurements of filling pressure should remain the gold standard for optimal risk stratification and management of patients with TC.

Innovations in atrial fibrillation ablation.

BACKGROUND: Catheter-based ablation to perform pulmonary vein isolation (PVI) has established itself as a mainstay in the rhythm control strategy of atrial fibrillation. This review article aims to provide an overview of recent advances in atrial fibrillation ablation technology. METHODS: We reviewed the available literature and clinical trials of innovations in atrial fibrillation ablation technologies including ablation catheter designs, alternative energy sources, esophageal protection methods, electroanatomical mapping, and novel ablation targets. RESULTS: Innovative radiofrequency (RF) catheter designs maximize energy delivery while avoiding overheating associated with conventional catheters. Single-shot balloon catheters in the form of cryoballoons, radiofrequency, and laser balloons have proven effective at producing pulmonary vein isolation and improving procedural efficiency and reproducibility. Pulsed field ablation (PFA) is a highly anticipated novel nonthermal energy source under development, which demonstrates selective ablation of the myocardium, producing durable lesions while also minimizing collateral damage. Innovative devices for esophageal protection including esophageal deviation and cooling devices have been developed to reduce esophageal complications. Improved electroanatomical mapping systems are being developed to help identify additional non-pulmonary triggers, which may benefit from ablation, especially with persistent atrial fibrillation. Lastly, the vein of Marshall alcohol ablation has been recently studied as an adjunct therapy for improving outcomes with catheter ablation for persistent atrial fibrillation. CONCLUSIONS: Numerous advances have been made in the field of atrial fibrillation ablation in the past decade. While further long-term data is still needed for these novel technologies, they show potential to improve procedural efficacy and safety.

Antacid Therapy in Coronary Artery Disease and Heart Failure: Proton Pump Inhibitors vs. H2 Receptor Blockers.

PURPOSE: Acid suppressive therapy using histamine H2 receptor antagonists (H2RAs) and proton pump inhibitors (PPIs) can be utilized for the prevention of gastrointestinal bleeding (GIB) among patients with cardiovascular disease receiving dual antiplatelet therapy (DAPT). However, emerging data suggests underlying associations between PPI or H2RA use and cardiovascular disease incidence, progression, and mortality. This review explores the history of acid suppressive therapies and their use in cardiovascular disease patients and the growing evidence in support of H2RA use. RECENT FINDINGS: PPIs were originally championed as better than H2RAs for preventing GIB events in cardiovascular disease patients on DAPT therapy, but there is evidence to suggest that drug-drug interactions between clopidogrel and PPIs may translate to worse cardiovascular outcomes. Studies demonstrating PPI superiority in the setting of DAPT were also limited due to small sample sizes and high levels of bias. Consequently, there is renewed interest in H2RAs for patients on DAPT with some data demonstrating similar or improved clinical outcomes over PPI therapy. Additionally, studies have discovered a possible role for H2RAs in the management of heart failure (HF) incidence, symptoms, and mortality. Studies comparing H2RAs and PPIs in patients on DAPT have demonstrated mixed results for cardiovascular and GIB outcomes, with several studies being underpowered and limited by biases. Recent clinical and pre-clinical studies now support the noninferiority of H2RAs for major outcomes and even utility in HF. These findings suggest that H2RAs may warrant reconsideration as an acid suppressive therapy over PPIs for patients on DAPT or with HF.

Mental Health and Access to Medical Care in Patients with Chronic Cardiovascular Conditions: An Analysis of the Behavior Risk Factor Surveillance System.

INTRODUCTION: Poor mental health is associated with worse outcomes for chronic diseases. It is unclear whether mental illness predisposes to difficulties with healthcare access. METHODS: Using a combined dataset of the 2016-2019 Behavioral Risk Factor Surveillance System, this study focused on individuals who reported a chronic cardiovascular condition. Weighted multivariable logistic regression analyses were used to explore the association between domains of mental health and measures of healthcare access including delaying medical care, more than one year since last routine checkup, lack of a primary care physician, and cost-related medication nonadherence. RESULTS: Among 1,747,397 participants, 27% had a chronic cardiovascular condition, 12% had clinical depression, and 12% had poor mental health. Those with poor mental health (OR 3.20 [3.08 - 3.33]) and clinical depression (OR 2.43 [2.35 - 2.52]) were more likely to report delays in medical care. Those with greater stress frequency (OR 8.47 [6.84 - 10.49] stressed all of the time), lower levels of emotional support received (OR 3.07 [2.21 - 4.26] rarely get needed emotional support), and greater life dissatisfaction (6.66 [4.14 - 10.70] very dissatisfied) reported greater delays in medical care. CONCLUSIONS: Individuals with poor mental health have greater difficulty accessing medical care independent of socioeconomic variables.

Left Ventricle Mass Regression After Surgical or Transcatheter Aortic Valve Replacement in Veterans.

BACKGROUND: Differences in left ventricular mass regression (LVMR) between transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) have not been studied. We present clinical and echocardiographic data from veterans who underwent TAVR and SAVR, evaluating the degree of LVMR and its association with survival. METHODS: We retrospectively reviewed TAVR (n = 194) and SAVR (n = 365) procedures performed in veterans from 2011 to 2019. After 1:1 propensity matching, we evaluated mortality and secondary outcomes. Echocardiographic data (median follow-up 957 days, interquartile range 483-1652 days) were used to evaluate LVMR, its association with survival, and predictors of LVMR. RESULTS: There was no difference between SAVR and TAVR patients in mortality (for up to 8 years), stroke at 30 days, myocardial infarction, renal failure, prolonged ventilation, reoperation, or structural valve deterioration. SAVR patients (67.3% [101 of 150]) were more likely to have LVMR than TAVR patients (55.7% [44 of 79], P = .11). The magnitude of LVMR was greater for the SAVR patients (median, -23.3%) than for the TAVR patients (median, -17.8%, P = .062). SAVR patients with LVMR had a survival advantage over SAVR patients without LVMR (P = .016). However, LVMR was not associated with greater survival in TAVR patients (P = .248). CONCLUSIONS: SAVR patients were more likely to have LVMR and had a greater magnitude of LVMR than TAVR patients. LVMR was associated with better survival in SAVR patients, but not in TAVR patients.

Cilostazol: a Review of Basic Mechanisms and Clinical Uses.

Primarily used in the treatment of intermittent claudication, cilostazol is a 2-oxyquinolone derivative that works through the inhibition of phosphodiesterase III and related increases in cyclic adenosine monophosphate (cAMP) levels. However, cilostazol has been implicated in a number of other basic pathways including the inhibition of adenosine reuptake, the inhibition of multidrug resistance protein 4, among others. It has been observed to exhibit antiplatelet, antiproliferative, vasodilatory, and ischemic-reperfusion protective properties. As such, cilostazol has been investigated for clinical use in a variety of settings including intermittent claudication, as an adjunctive for reduction of restenosis after coronary and peripheral endovascular interventions, and in the prevention of secondary stroke, although its widespread implementation for indications other than intermittent claudication has been limited by relatively modest effect sizes and lack of studies in western populations. In this review, we highlight the pleiotropic effects of cilostazol and the evidence for its clinical use.

Diagnosis of Occlusion Myocardial Infarction in Patients with Left Bundle Branch Block and Paced Rhythms.

PURPOSE OF REVIEW: A number of criteria have been developed to aid with the diagnosis of occlusion myocardial infarction (OMI) in patients with left bundle branch block (LBBB) and ventricular paced rhythms (VPR). The current guidelines do not provide clear preference for any specific ECG criteria in LBBB and paced rhythm patients. RECENT FINDINGS: This review delineates the difficulties of electrocardiographic diagnosis of OMI in both LBBB and VPR patients. We describe the original Sgarbossa and the newer criteria and their diagnostic performances. We highlight the expected changes of newer pacing modalities and how they may interfere with the electrocardiographic diagnosis of OMI. We recommend utilizing the Cai et al. algorithm, which combines clinical assessment with the Smith Modified Sgarbossa ECG criteria, for both LBBB and right ventricular pacing patients with suspected OMI. There is limited data concerning ECG changes of OMI in patients with the newer pacing modalities, such as biventricular, His-bundle, or left bundle branch pacing.

Gender disparities in difficulty accessing healthcare and cost-related medication non-adherence: The CDC behavioral risk factor surveillance system (BRFSS) survey.

Ensuring healthcare access is critical to maintain health and prevent illness. Studies demonstrate gender disparities in healthcare access. Less is known about how these vary with age, race/ethnicity, and atherosclerotic cardiovascular disease. We utilized cross-sectional data from 2016 to 2019 CDC Behavioral Risk Factor Surveillance System (BRFSS), a U.S. telephone-based survey of adults (≥18 years). Measures of difficulty accessing healthcare included absence of healthcare coverage, delay in healthcare access, absence of primary care physician, >1-year since last checkup, inability to see doctor due to cost, and cost-related medication non-adherence. We studied the association between gender and these variables using multivariable-adjusted logistic regression models, stratifying by age, race/ethnicity, and atherosclerotic cardiovascular disease status. Our population consisted of 1,737,397 individuals; 54% were older (≥45 years), 51% women, 63% non-Hispanic White, 12% non-Hispanic Black,17% Hispanic, 9% reported atherosclerotic cardiovascular disease. In multivariable-adjusted models, women were more likely to report delay in healthcare access: odds ratio (OR) and (95% confidence interval): 1.26 (1.11, 1.43) [p < 0.001], inability to see doctor due to cost: 1.29 (1.22, 1.36) [p < 0.001], cost-related medication non-adherence: 1.24 (1.01, 1.50) [p = 0.04]. Women were less likely to report lack of healthcare coverage: 0.71 (0.66, 0.75) [p < 0.001] and not having a primary care physician: 0.50 (0.48, 0.52) [p < 0.001]. Disparities were pronounced in younger (<45 years) and Black women. Identifying these barriers, particularly among younger women and Black women, is crucial to ensure equitable healthcare access to all individuals.

Long-Term Outcomes of Veteran Patients After Transcatheter Aortic Valve Replacement.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become a mainstay treatment for severe aortic stenosis and is increasingly used for veterans, producing excellent short-term outcomes. There is a paucity of long-term outcome data after TAVR in the veteran population. METHODS: We examined consecutive patients who underwent TAVR at a single Veterans Affairs medical center through 2019. Baseline characteristics, echocardiographic and angiographic variables, and clinical outcomes were abstracted. All-cause mortality was the primary outcome of interest. Factors associated with all-cause mortality and cardiac-specific mortality, including the presence of significant non-revascularized coronary artery disease (CAD), were assessed with multivariable regression and competing-risk analyses. RESULTS: The 189 consecutive patients enrolled (mean age, 76.6 ± 8.4 years) had a median Society of Thoracic Surgeons (STS) score of 6.0 (interquartile range [IQR], 4.0-8.5). After a maximum follow-up of 7.5 years, 71 (37.6%) deaths occurred, of which 76% had a cardiac cause. Median overall survival was 3.55 years (95% confidence interval [CI], 3.21-5.30); significant graded differences were observed across STS risk subgroups (P<.001). After multivariable adjustment, CAD was significantly associated with cardiac mortality (hazard ratio [HR], 2.6; 95% CI, 1.3-5.3) and all-cause mortality (HR, 2.2; 95% CI, 1.1-4.3). Other independent variables associated with all-cause mortality included age (P=.01), baseline creatinine (P<.01), and chronic obstructive pulmonary disease (P=.03). Baseline ejection fraction (P=.04), age (P<.01), creatinine (P=.02), and vascular disease (P=.04) were independently associated with cardiac-specific mortality. CONCLUSION: Long-term survival of veterans after TAVR is comparable to that of their non-veteran counterparts. Significant CAD, along with age and select comorbidities, was associated with poorer survival.

Prevalence and predictors of cost-related medication nonadherence in individuals with cardiovascular disease: Results from the Behavioral Risk Factor Surveillance System (BRFSS) survey.

Medication nonadherence is highly prevalent among patients with chronic cardiovascular disease. Poor adherence has been associated with increased morbidity and mortality. Medication cost is a major driver for medication nonadherence. Utilizing data from the 2016 to 2018 Behavioral Risk Factor Surveillance System (BRFSS) survey, we estimated the prevalence of cost-related medication nonadherence (CRMNA) among the overall population and among individuals who reported a history of diabetes, atherosclerotic cardiovascular disease (ASCVD), or hypertension. We then performed multivariable logistic regression to analyze sociodemographic factors associated with CRMNA. Our study population consisted of 142,577 individuals of whom 24% were older than 65 years, 47% were men, 66% were White, 17% Black, 35% had hypertension, 13% had diabetes mellitus, and 10% had ASCVD. CRMNA was reported in 10% of the overall population, 12% among those with hypertension, 17% among those with diabetes, and 17% among those with ASCVD. Age below 65 years, female gender, unemployment, lower income, lower educational attainment, having at least 1 comorbidity, and living in a state that did not expand Medicaid were independently associated with CRMNA. The prevalence of CRMNA increased with greater number of these high-risk sociodemographic factors. We conclude that the prevalence of CRMNA is 10% among U.S. adults overall and is higher among those with common chronic diseases. Risk factors associated with CRMNA should be addressed in order to improve adherence rates and health outcomes among high-risk individuals.

Prevalence and Determinants of Difficulty in Accessing Medical Care in U.S. Adults.

INTRODUCTION: Ensuring adequate access to health care is essential for timely delivery of preventive services. It is important to evaluate the prevalence and determinants of difficulty in accessing medical care in the overall U.S. population and among those with high-risk chronic conditions. METHODS: The study utilized cross-sectional data from the 2016-2019 Behavioral Risk Factor Surveillance System, a nationally representative telephone-based survey of adults aged ≥18 years. The prevalence and sociodemographic characteristics associated with difficulty in receiving medical care were assessed, including regional variations across U.S. states. RESULTS: The prevalence of difficulty in accessing medical care was 14% overall, 15% among those with hypertension, 15% among those with diabetes mellitus, and 17% among those with atherosclerotic cardiovascular disease. Age 18-34 years, having less than high school education, having annual household income <$75,000, unemployment, and living in a state without Medicaid expansion were all associated with a higher risk of not accessing medical care. The prevalence of difficulty in accessing medical care was 27% among individuals with ≥3 of these sociodemographic characteristics. There was regional variation across the U.S. states in the distribution of difficulty in accessing medical care with a median of 13.6% (IQR=11.3%-15.9%) for the overall population: 16.3% (IQR=14.1%-19.0%) among those living in states without Medicaid expansion versus 12.7% (IQR=10.9%-15.6%) among those living in states with Medicaid expansion (p=0.01). CONCLUSIONS: In total, 1 in 7 adults report difficulty in accessing medical care. This prevalence is nearly 1 in 4 adults with ≥3 sociodemographic characteristics related to difficulty in accessing medical care. There are regional variations in the distribution of the difficulty in accessing medical care, especially among individuals living in states that have not undergone Medicaid expansion.

Transcatheter aortic valve replacement after chest radiation: A propensity-matched analysis.

BACKGROUND: Chest radiation therapy (CRT) for malignant thoracic neoplasms is associated with development of valvular heart disease years later. As previous radiation exposure can complicate surgical treatment, transcatheter aortic valve replacement (TAVR) has emerged as an alternative. However, outcomes data are lacking for TAVR patients with a history of CRT. METHODS: We conducted a retrospective study of all patients who underwent a TAVR procedure at a single institution between September 2012 and November 2018. Among 1341 total patients, 50 had previous CRT. These were propensity-matched in a 1:2 ratio to 100 patients without history of CRT. Thirty-day adverse events were analyzed with generalized estimating equation models. Overall mortality was analyzed with stratified Cox regression modelling. RESULTS: Median clinical follow-up was 24 months (interquartile range [IQR], 12-44 months). There was no difference between CRT and non-CRT patients in overall mortality (hazard ratio [HR] 0.84 [0.37-1.90], P = 0.67), 30-day mortality (HR 3.1 [0.49-20.03], P = 0.23), or 30-day readmission rate (HR 1.0 [0.43-2.31], P = 1). There were no differences in the rates of most adverse events, but patients with CRT history had higher rates of postprocedural respiratory failure (HR 3.63 [1.32-10.02], P = 0.01) and permanent pacemaker implantation (HR 2.84 [1.15-7.01], P = 0.02). CONCLUSIONS: For patients with aortic valve stenosis and previous CRT, TAVR is safe and effective, with outcomes similar to those in the general aortic stenosis population. Patients with history of CRT are more likely to have postprocedural respiratory failure and to require permanent pacemaker implantation.

Complete percutaneous apical access and closure: Short and intermediate term outcomes.

OBJECTIVES: To examine the safety of utilizing transapical access during structural interventions. BACKGROUND: Complex interventions of the mitral or aortic region sometimes require coaxial forces to orient and deliver devices. Apical access can provide coaxial countertraction for either transseptal or retrograde aortic access. This manuscript describes the single center experience of small bore transapical access. METHODS: Retrospective review of cases from 2013 to 2018 at Henry Ford Hospital was performed. Patient demographics and procedure characteristics were abstracted to describe the safety of transapical access using small bore sheaths. RESULTS: A total 21 cases were performed at Henry Ford, most of them for transcatheter mitral valve replacement (81%). The mean sheath size used was 4.7 ± 0.9 Fr and protamine was used at the end of 57% of cases. All patients received nitinol-based plugs, 80.1% were from the Amplatz Duct Occluder II type. Four major complications related apical puncture occurred, two pericardial effusions, two hemothorax. Over a median follow time of 430 days (IQR 50-652) a total of five deaths occurred, two related to the procedure and three late deaths with a median time of 362 days (range 205-628 days). No deaths were associated with transapical access. Echocardiographic follow up did not detect any late structural complications from occluder devices. CONCLUSIONS: Transapical access and closure with nitinol-based devices is feasible and facilitates complex interventions where coaxial forces are need for device delivery and alignment. The most common complication is bleeding and this should be kept in perspective when treating high-risk patients.

Resolution of Hypoxia and Ascites With Percutaneous Intervention of Mustard Baffle Obstruction and Leak.

A 45-year-old man with history of Mustard repair for transposition of the great arteries, cirrhosis, and chronic hypoxemic respiratory failure presented for subacute worsening of his chronic symptoms, which were found to be secondary to a previously unrecognized baffle stenosis and leak. Percutaneous intervention resolved his ascites and hypoxia. (Level of Difficulty: Intermediate.).

Antiplatelet therapy and the risk of ischemic and hemorrhagic complications associated with Pipeline embolization of cerebral aneurysms: a systematic review and pooled analysis.

BACKGROUND: Pipeline embolization devices (PEDs) are increasingly used in the treatment of cerebral aneurysms. Yet, major ischemic or hemorrhagic complications after PED treatment associated with antiplatelet regimens are not well-established. OBJECTIVE: To investigate the risk of ischemic and hemorrhagic complications associated with common antiplatelet regimens following PED treatment, and to examine whether platelet function testing (PFT) is associated with a lower risk of these complications. METHODS: We searched Medline, Embase, and Cochrane from 2009 to 2017. Twenty-nine studies were included that had reported a uniform antiplatelet regimen protocol and had provided data on major ischemic and hemorrhagic complications following PED treatment. Random-effect meta-analysis was used to pool overall ischemic and hemorrhagic event rates across studies. The rate of these complications with respect to the antithrombotic regimen and PFT was assessed by χ2 proportional tests. RESULTS: Overall, 2002 patients (age 55.9 years, 76% female) were included. A low-dose acetylsalicylic acid (ASA) regimen before and after PED treatment was associated with a higher rate of late ischemic complications than with high-dose ASA therapy (2.62 (95% CI 1.46 to 4.69) and 2.56 (1.41 to 4.64), respectively). Duration of post-procedure clopidogrel therapy <6 months was associated with greater rates of ischemic complications (1.56, 95% CI 1.11 to 2.20) than a clopidogrel regimen of ≥6 months. Performing PFT before PED treatment was not associated with the risk of ischemic complications (1.27, 95% CI 0.77 to 2.10). CONCLUSION: High-dose ASA therapy and clopidogrel treatment for at least 6 months were associated with a reduced incidence of ischemic events, without affecting the risk of hemorrhagic events.

Comparison of the efficacy and safety of thrombectomy devices in acute stroke : a network meta-analysis of randomized trials.

INTRODUCTION: Mechanical thrombectomy (MT) is increasingly used for large-vessel occlusions (LVO), but randomized clinical trial (RCT) level data with regard to differences in clinical outcomes of MT devices are limited. We conducted a network meta-analysis (NMA) that enables comparison of modern MT devices (Trevo, Solitaire, Aspiration) and strategies (stent retriever vs aspiration) across trials. METHODS: Relevant RCTs were identified by a systematic review. The efficacy outcome was 90-day functional independence (modified Rankin Scale (mRS) score 0-2). Safety outcomes were 90-day catastrophic outcome (mRS 5-6) and symptomatic intracranial hemorrhage (sICH). Fixed-effect Bayesian NMA was performed to calculate risk estimates and the rank probabilities. RESULTS: In a NMA of six relevant RCTs (SWIFT, TREVO2, EXTEND-IA, SWIFT-PRIME, REVASCAT, THERAPY; total of 871 patients, 472 Solitaire vs medical-only, 108 Aspiration vs medical-only, 178 Trevo vs Merci, and 113 Solitaire vs Merci) with medical-only arm as the reference, Trevo had the greatest functional independence (OR 4.14, 95% credible interval (CrI) 1.41-11.80; top rank probability 92%) followed by Solitaire (OR 2.55, 95% CrI 1.75-3.74; top rank probability 72%). Solitaire and Aspiration devices had the greatest top rank probability with respect to low sICH and catastrophic outcomes (76% and 91%, respectively), but without significant differences between each other. In a separate network of seven RCTs (MR-CLEAN, ESCAPE, EXTEND-IA, SWIFT-PRIME, REVASCAT, THERAPY, ASTER; 1737 patients), first-line stent retriever was associated with a higher top rank probability of functional independence than aspiration (95% vs 54%), with comparable safety outcomes. CONCLUSIONS: These findings suggest that Trevo and Solitaire devices are associated with a greater likelihood of functional independence whereas Solitaire and Aspiration devices appear to be safer.
