RESUMO
BACKGROUND: Although covered stents (CS) represent a potentially life-saving intervention for coronary perforation (CAP), their application has expanded to other contexts, including coronary aneurysms (CAA). However, data regarding mid- and long-term outcomes of CS in these settings scenarios remains limited. AIMS: This meta-analysis aims to evaluate major adverse cardiac events (MACE) from discharge through long-term follow-up in patients undergoing percutaneous coronary intervention with the new generation polyurethane-covered cobalt-chromium PK Papyrus CS. METHODS: We conducted a meta-analysis of data from three observational trials that included long-term follow-up of patients who underwent PK Papyrus CS implantation: Papyrus-Spain, SOS PK Papyrus, and PAST-PERF registry. RESULTS: 332 patients underwent PK Papyrus CS implantation, 236 (71.1%) for CAP, 70 (21.1%) for CAA and 26 (7.8%) for other indications. After a mean follow-up of 16.2 months, the MACE was 14.3%, with Target Lesion Revascularization (TLR) being the most frequent (8.5%), followed by stent thrombosis (ST), 3.3% and cardiac death (CD), 2.6%. Comparing CAP and CAA subgroups, the MACE rate in CAA was significantly higher than CAP (21.4% vs 9.7%, p < 0.01), primary driven by ST (CAA: 8.6% vs CAP: 1.3%; p = 0.0015). CONCLUSIONS: The clinical outcomes following PK Papyrus CS implantation are deemed acceptable, considering the challenging scenarios and the existing alternative treatments. However, MACE rates in patients with CAA who received Papyrus PK CS were significantly higher than in those with CAP, underscoring the importance of meticulous patient selection and optimization of CS in these complex patients and coronary anatomies.
RESUMO
Catheter-induced stent dislodgement may occur when attempting to withdraw the stent into the guide-catheter particularly in cases of guiding-catheter co-axiality issues. We present the management of a catheter-induced stent dislodgement with simultaneous loss of wire position.

BACKGROUND: Cardiac magnetic resonance imaging may provide a non-invasive alternative to coronary angiography for differentiating between ischaemic and non-ischaemic cardiomyopathy in cases of unexplained reduced left ventricular ejection fraction. AIM: The CAMAREC study aims to evaluate the diagnostic accuracy of cardiac magnetic resonance imaging in predicting significant coronary artery disease in patients with reduced left ventricular ejection fraction, using coronary angiography as the gold standard for comparison. METHODS: CAMAREC is a prospective cohort study of 406 patients in 10 centres with newly diagnosed, unexplained left ventricular ejection fraction ≤ 45%. Cardiac magnetic resonance imaging and coronary angiography will be conducted within a 2-week interval, starting with cardiac magnetic resonance imaging; independent committees will review the results blindly. Primary outcome is sensitivity of detecting ischaemic scar on cardiac magnetic resonance imaging for predicting significant coronary artery disease on coronary angiography according to Felker's criteria. Secondary outcomes include specificity and positive and negative predictive values (with 95% confidence intervals) of cardiac magnetic resonance imaging for predicting significant coronary artery disease in patients with reduced left ventricular ejection fraction, kappa concordance coefficient between cardiac magnetic resonance imaging and coronary angiography for diagnosing the affected myocardial territory, and the impact of cardiac magnetic resonance imaging on revascularization decisions. Two ancillary studies will evaluate the incremental cost-effectiveness of using cardiac magnetic resonance imaging first versus coronary angiography first, and the sensitivity of pre- and postcontrast T1-mapping for predicting significant coronary artery disease in patients with reduced left ventricular ejection fraction. CONCLUSION: Our study protocol is designed to rigorously evaluate cardiac magnetic resonance imaging as a non-invasive alternative to coronary angiography in patients with unexplained reduced left ventricular ejection fraction. The results will have significant implications for patient management, and may support growing evidence for the clinical utility of cardiac magnetic resonance imaging.

Objectives: Myocardial injury assessment from delayed enhancement magnetic resonance images is routinely limited to global descriptors such as size and transmurality. Statistical tools from computational anatomy can drastically improve this characterization, and refine the assessment of therapeutic procedures aiming at infarct size reduction. Based on these techniques, we propose a new characterization of myocardial injury up to the pixel resolution. We demonstrate it on the imaging data from the Minimalist Immediate Mechanical Intervention randomized clinical trial (MIMI: NCT01360242), which aimed at comparing immediate and delayed stenting in acute ST-Elevation Myocardial Infarction (STEMI) patients. Methods: We analyzed 123 patients from the MIMI trial (62 ± 12 years, 98 male, 65 immediate 58 delayed stenting). Early and late enhancement images were transported onto a common geometry using techniques inspired by statistical atlases, allowing pixel-wise comparisons across population subgroups. A practical visualization of lesion patterns against specific clinical and therapeutic characteristics was also proposed using state-of-the-art dimensionality reduction. Results: Infarct patterns were roughly comparable between the two treatments across the whole myocardium. Subtle but significant local differences were observed for the LCX and RCA territories with higher transmurality for delayed stenting at lateral and inferior/inferoseptal locations, respectively (15% and 23% of myocardial locations with a p-value <0.05, mainly in these regions). In contrast, global measurements were comparable for all territories (no statistically significant differences for all-except-one measurements before standardization / for all after standardization), although immediate stenting resulted in more subjects without reperfusion injury. Conclusion: Our approach substantially empowers the analysis of lesion patterns with standardized comparisons up to the pixel resolution, and may reveal subtle differences not accessible with global observations. On the MIMI trial data as illustrative case, it confirmed its general conclusions regarding the lack of benefit of delayed stenting, but revealed subgroups differences thanks to the standardized and finer analysis scale.
RESUMO
BACKGROUND: European guidelines order management of patients with ST-segment elevation myocardial infarction (STEMI) less than 12 hours. They encourage healthcare networks to rapid coronary reperfusion strategy depending on the distance of the patient from the PCI center. OBJECTIVE: To determine impact of out-of-hospital presentation of patients with STEMI in remote areas within the framework of a care network, and to define the degree of compliance with local recommendations, and its prognostic impact. METHOD: Over three years (2017-2019), from the RESURCOR prospective register, 310 patients with STEMI less than 12 hours were out-of hospital managed and transferred to Metrolpole Savoie Hospital in Chambéry. Depending on the "door in to PCI center" time, patients are divided into 2 groups: "Local area" for a time ≤ 60 min and "Remote area" for a time > 60 min. RESULTS: 51 patients were in the "Local area" group and 259 patients in the "Remote area" group with an average age of 63.36 years, without significant difference between the two groups. We noted more men, smokers and a higher heart rate in the "Local area" group (p = 0.015; p = 0.005 and p = 0.035 respectively). The median "call-EMS care" delay was similar at 24 min in each group. Seventy-five patients (29%) in the "Remote area" group had fibrinolysis versus only one patient in the "Local area" group (p < 0.001). Among them, 42 patients (56%) had rescue PCI, in 40% with 90 min of fibrinolytic administration. The presence of a primary care physicians "PCP" was reported in 39 cases of the "remote area" group. PCP intervention increased the rate of bolus of fibrinolytics within 10 min from STEMI diagnosis (69.2% vs 21.8%, p < 0.001), increased the rate of bolus treatment within 10 min from STEMI diagnosis within 10 min (60% vs 16% p < 0.001) and reduced the rate of rescue PCI (44.4% vs 62.5%, p = 0.035). Total ischemia time was significantly shorter in the "Local area" group (144 min vs 175 min, p = 0.005). No significant difference concerning the in-hospital outcomes was found between 2 groups. Concerning compliance with local recommendations in the "remote area" group, among those eligible for thrombolysis, 135 patients (64,2 %) had an inappropriate primary PCI (error in estimated time from STEMI diagnosis to PCI-mediated reperfusion (< 1 h)), which was associated with a higher rate of serious arrhythmias (11.1% vs 2.7% respectively, p = 0.035). Regardless of the group, if the strategy was primary PCI 22% of patients had angiography within 60 minutes after STEMI diagnosis. CONCLUSION: In this work, the temporal distance from the PCI room does not seem to be responsible for a more pejorative in-hospital outcomes, unlike the proportion of inappropriate primary PCI which increase serious arrhythmias.

In the last decade, a large number of clinical trials have been deployed using Cardiac Magnetic Resonance (CMR) to evaluate cardioprotective strategies aiming at reducing the irreversible myocardial damage at the time of reperfusion. In these studies, segmentation and quantification of myocardial infarct lesion are often performed with a commercial software or an in-house closed-source code development thus creating a barrier for reproducible research. This paper introduces CMRSegTools: an open-source application software designed for the segmentation and quantification of myocardial infarct lesion enabling full access to state-of-the-art segmentation methods and parameters, easy integration of new algorithms and standardised results sharing. This post-processing tool has been implemented as a plug-in for the OsiriX/Horos DICOM viewer leveraging its database management functionalities and user interaction features to provide a bespoke tool for the analysis of cardiac MR images on large clinical cohorts. CMRSegTools includes, among others, user-assisted segmentation of the left-ventricle, semi- and automatic lesion segmentation methods, advanced statistical analysis and visualisation based on the American Heart Association 17-segment model. New segmentation methods can be integrated into the plug-in by developing components based on image processing and visualisation libraries such as ITK and VTK in C++ programming language. CMRSegTools allows the creation of training and testing data sets (labeled features such as lesion, microvascular obstruction and remote ROI) for supervised Machine Learning methods, and enables the comparative assessment of lesion segmentation methods via a single and integrated platform. The plug-in has been successfully used by several CMR imaging studies.

OBJECTIVE: To assess the quality of life (QOL) and describe associated factors in patients with chronic heart failure (HF) living in a low-income population in West Africa. METHODS: This is was a cross-sectional study conducted from January 2017 to June 2018, in the department of cardiology of the University Teaching Hospital (CHU-Campus) in Lomé (Togo). Enrolled patients had stable chronic HF and have been hospitalized in the past 6 months; QOL was assessed using the Minnesota Living with Heart Failure questionnaire (MLHFQ). RESULTS: 171 patients were included (women = 40.9%, 33% unschooled, 75% without health insurance; 46.8% in NYHA class II). The prevalence of depression was 62%. The mean total score of MLHFQ was 37.2 ± 22.3. In univariate analysis, there was a positive correlation between the total score and the following factors: age (r= 0.33, p Ë0.0001), NYHA classes (r= 0.67, p Ë0.0001), number of rehospitalizations (r= 0.61, p Ë0.0001), number of comorbidities (r= 0.43, p Ë0.0001), and the depression score (r= 0.67, p Ë0.0001). After adjustments, positive correlation persisted with NYHA classes (p Ë0.0001), number of rehospitalizations (p= 0.02), and depression (p Ë0.0001). CONCLUSION: The QOL of HF patients was moderately impaired and was comparable to values reported among high-income populations. Factors associated with poor quality of life were advanced NYHA classes, number of rehospitalizations, and depression.

Introduction: Long-term follow-up after an acute coronary syndrome (ACS) presents a crucial challenge due to the high residual cardiovascular risk and the potential for major bleeding events. Although several treatment strategies are available, this article focuses on patients who have undergone percutaneous coronary intervention (PCI) for ACS, which is a frequent clinical situation. This position paper aims to support physicians in daily practice to improve the management of ACS patients. Material and methods: A group of recognized international and French experts in the field provides an overview of current evidence-based recommendations - supplemented by expert opinion where such evidence is lacking - and a practical guide for the management of patients with ACS after hospital discharge. Results: The International Collaborative Group underlines the need of a shared collaborative approach, and a care plan individualized to the patient's risk profile for both ischaemia and bleeding. Each follow-up appointment should be viewed as an opportunity to optimize the personalized approach, to reduce adverse clinical outcomes and improve quality of life. As risks - both ischaemic and haemorrhagic - evolve over time, the risk-benefit balance should be assessed in an ongoing dynamic process to ensure that patients are given the most suitable treatment at each time point. Conclusions: This Expert Opinion aims to help clinicians with a practical guide underlying the proven strategies and the remaining gaps of evidence to optimize the management of coronary patients.
RESUMO
AIM: To assess the effects of 1- or ≥3-month dual antiplatelet therapy (DAPT) in high bleeding risk (HBR) patients who received biodegradable-polymer sirolimus-eluting stents for complex percutaneous coronary intervention (PCI) and/or acute coronary syndrome (ACS). METHODS AND RESULTS: In the MASTER DAPT trial, 3383 patients underwent non-complex (abbreviated DAPT, n = 1707; standard DAPT, n = 1676) and 1196 complex (abbreviated DAPT, n = 588; standard DAPT, n = 608) PCI. Co-primary outcomes at 335 days were net adverse clinical events [NACE; composite of all-cause death, myocardial infarction, stroke, and bleeding academic research consortium (BARC) 3 or 5 bleeding events]; major adverse cardiac or cerebral events (MACCE; all-cause death, myocardial infarction, and stroke); and Types 2, 3, or 5 BARC bleeding. Net adverse clinical events and MACCE did not differ with abbreviated vs. standard DAPT among patients with complex [hazard ratio (HR): 1.03, 95% confidence interval (CI): 0.69-1.52, and HR: 1.24, 95% CI: 0.79-1.92, respectively] and non-complex PCI (HR: 0.90, 95% CI: 0.71-1.15, and HR: 0.91, 95% CI: 0.69-1.21; Pinteraction = 0.60 and 0.26, respectively). BARC 2, 3, or 5 was reduced with abbreviated DAPT in patients with and without complex PCI (HR: 0.64; 95% CI: 0.42-0.98, and HR: 0.70; 95% CI: 0.55-0.89; Pinteraction = 0.72). Among the 2816 patients with complex PCI and/or ACS, NACE and MACCE did not differ and BARC 2, 3, or 5 was lower with abbreviated DAPT. CONCLUSION: In HBR patients free from recurrent ischaemic events at 1 month, DAPT discontinuation was associated with similar NACE and MACCE and lower bleeding rates compared with standard DAPT, regardless of PCI or patient complexity. CLINICAL TRIAL REGISTRATION: This trial is registered with ClinicalTrials.gov, number NCT03023020, and is closed to new participants, with follow-up completed.

Background: In the observational SUPER-MIMI study, a minimalist immediate mechanical intervention (MIMI) technique-which involves restoring blood flow in the acute phase and postponing stenting-was shown to be safe and effective among patients with a high thrombotic burden after ST-segment elevation myocardial infarction (STEMI). We aim to assess whether a non-stenting strategy after a SUPER-MIMI strategy was safe at 4-year follow-up in patients enrolled in the SUPER-MIMI study who were not stented. Methods: This prospective cohort study assessed the long-term outcomes of a subgroup of patients included in the SUPER-MIMI study. Results: Among the 155 patients enrolled in the SUPER-MIMI study, 57 patients (36.8%) benefited from a conservative management (without stenting or balloon angioplasty) and were included in the current substudy. The mean duration of follow-up was 4.1±1.0 years. Four patients (7.0%) presented definite culprit lesion re-thrombosis, all of which occurred in the right coronary artery. The re-thrombosis rate appeared to be higher among patients with larger vessels: 2.9%, 8.3%, and 28.6% in arteries with diameters of 3-<4, 4-<5, and ≥5 mm, respectively. The overall rate of target lesion revascularization was 10.5%. There was one cardiac death and three rehospitalizations for heart failure. Overall, 82.5% of patients remained event free at a mean of 4.1±1.0 years. Conclusions: Conservative management of non-stenotic culprit lesions after a SUPER-MIMI strategy was associated with a high rate of re-thrombosis, particularly in patients with large coronary arteries.
RESUMO
BACKGROUND: Highly thrombotic coronary lesions continue to be a serious and clinically significant problem that is not effectively and completely addressed by current technology. OBJECTIVES: We aimed to investigate whether a micro-net mesh (MNM) technology covering stent could preserve the index of microcirculatory resistance (IMR) after percutaneous coronary intervention (PCI) in patients with high thrombus burden. METHODS AND RESULTS: Fifty-two patients with non-ST elevation myocardial infarction or ST Elevation Myocardial Infarction and high thrombus burden (TIMI thrombus grade ≥ 3) were randomized into two groups, PCI with a MNM covering stent (MNM group, n = 25) and PCI with any commercially available stent (DES group, n = 27). As the primary endpoint, IMR was measured immediately after PCI using a pressure-temperature sensor-tipped coronary wire. The secondary endpoint was left ventricular ejection fraction (LVEF) at 6 months of follow-up. The IMR in the MNM group was significantly lower in comparison to the DES group (33.2 [21.3, 48.9] vs. 57.2 [39.9, 98.0], p = 0.005). No significant differences were observed in baseline LVEF (54.5 ± 10.2% vs. 53.1 ± 6.87%, p = .57), while LVEF was significantly improved at follow-up in the MNM group (61.1 ± 7.1% vs. 53.9 ± 6.35%, p = .0001). CONCLUSION: MNM technology significantly improved coronary microvascular dysfunction after PCI in patient with acute coronary syndrome and appears as a useful technological option for thrombus management.

BACKGROUND: The optimal management of patients with ST-segment elevation myocardial infarction (STEMI) presenting late->12 hours following symptom onset-is still under debate. OBJECTIVES: The purpose of this study was to describe characteristics, temporal trends, and impact of revascularization in a large population of latecomer STEMI patients. METHODS: The authors analyzed the data of 3 nationwide observational studies from the FAST-MI (French Registry of Acute ST-elevation and non-ST-elevation Myocardial Infarction) program, conducted over a 1-month period in 2005, 2010, and 2015. Patients presenting between 12 and 48 hours after symptom onset were classified as latecomers. RESULTS: A total of 6,273 STEMI patients were included in the 3 cohorts, 1,169 (18.6%) of whom were latecomers. After exclusion of patients treated with fibrinolysis and patients deceased within 2 days after admission, 1,077 patients were analyzed, of whom 729 (67.7%) were revascularized within 48 hours after hospital admission. At 30-day follow-up, all-cause death rate was significantly lower among revascularized latecomers (2.1% vs 7.2%; P < 0.001). After a median follow-up of 58 months, the rate of all-cause death was 30.4 (95% CI: 25.7-35.9) per 1,000 patient-years in the revascularized latecomers group vs 78.7 (95% CI: 67.2-92.3) per 1,000 patient-years in the nonrevascularized latecomers group (P < 0.001). In multivariate analysis, revascularization of latecomer STEMI patients was independently associated with a significant reduction of mortality occurrence during follow-up (HR: 0.65 [95% CI: 0.50-0.84]; P = 0.001). CONCLUSIONS: Coronary revascularization of latecomer STEMI patients is associated with better short and long-term clinical outcomes.

AIMS: Periprocedural myocardial infarctions have been reported in the setting of planned percutaneous coronary intervention (PCI). We assessed the prevalence of nonculprit artery acute myocardial infarction (NCAMI) and its relationship with coronary artery characteristics, final infarct size, and 1-year adverse clinical outcomes in a population of anterior ST-elevated myocardial infarction (STEMI) patients. METHODS AND RESULTS: Late gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) studies were performed within 7 days of admission in 129 anterior STEMI patients from the CIRCUS trial treated by primary PCI. Infarct in the noninfarct artery territory (circumflex, right coronary) was assessed on LGE-CMR and T2-weighted images. Eleven (8.5%) patients exhibited NCAMI. The only independent characteristic significantly associated with NCAMI was the presence of multiple complex coronary lesions (odds ratio = 12.9, 95% confidence interval [3.1-53.4]; p < 0.001). There was a significantly increased infarct size in NCAMI patients compared to patients without NCAMI (45.8 ± 20.4% of the left ventricle [LV] vs. 31.0 ± 15.1% of LV, respectively; p = 0.02), with lower LV ejection fraction (46 ± 10% vs. 34 ± 8%, respectively; p < 0.001). CONCLUSION: NCAMIs are present in 8.5% of anterior STEMI patients and are significantly associated with multiple complex coronary lesions without significant relationship to any revascularization procedural technique. NCAMI was associated with a greater infarct size and reduced LVEF but not worse clinical outcomes at 1 year.

BACKGROUND: As any traumatic event, avalanches could trigger psychological disorders on survivors. Our objectives were to determine the prevalence of post-traumatic stress disorder among avalanche survivors and to evaluate post-traumatic stress disorder risks factors as well as the impact on quality of life. METHODS: A multicentre study was conducted in victims included in the North Alpine Avalanche Registry from 2014 to 2018. Data were collected through a standard questionnaire during semi-directed phone interviews. The primary outcome was the total score on the Impact of Event Scale Revised. Secondary outcomes were the Mental Component Scale and the Physical Component Scale scores of the Short Form 12 questionnaire. RESULTS: During the study period, 132 of 211 victims survived. Among the 107 victims included, 55 (51.4%) phone interviews were obtained. Six patients (10.9, 95% CI 1.76-20.05) had an Impact of Event Scale Revised score ≥ 33 indicating a strong probability for post-traumatic stress disorder. Median Mental Component Scale score was 39.0 (IQR 30.5-46.3) for post-traumatic stress disorder patients and 40.1 (IQR 36.5-43.4) for non post-traumatic stress disorder (p = 0.76). Median Physical Component Scale score was 39.4 (37.2-44.3) for post-traumatic stress disorder patients and 44.2 (39.1-46.8) for non post-traumatic stress disorder (p = 0.39). No significant difference in the quality of life in both populations was observed, and no independent risk factors of post-traumatic stress disorder was identified. CONCLUSION: Avalanche accidents may induce post-traumatic stress disorders among survivors in a comparable prevalence to the most traumatic event already studied. Early recognition and preventive measures should be set up in order to reduce the psychological burden in these victims. TRIAL REGISTRATION: NCT03936738 .

BACKGROUND: Systems of care have been challenged to control progression of the COVID-19 pandemic. Whether this has been associated with delayed reperfusion and worse outcomes in French patients with ST-segment elevation myocardial infarction (STEMI) is unknown. AIM: To compare the rate of STEMI admissions, treatment delays, and outcomes between the first peak of the COVID-19 pandemic in France and the equivalent period in 2019. METHODS: In this nationwide French survey, data from consecutive STEMI patients from 65 centres referred for urgent revascularization between 1 March and 31 May 2020, and between 1 March and 31 May 2019, were analysed. The primary outcome was a composite of in-hospital death or non-fatal mechanical complications of acute myocardial infarction. RESULTS: A total of 6306 patients were included. During the pandemic peak, a 13.9±6.6% (P=0.003) decrease in STEMI admissions per week was observed. Delays between symptom onset and percutaneous coronary intervention were longer in 2020 versus 2019 (270 [interquartile range 150-705] vs 245 [140-646]min; P=0.013), driven by the increase in time from symptom onset to first medical contact (121 [60-360] vs 150 [62-420]min; P=0.002). During 2020, a greater number of mechanical complications was observed (0.9% vs 1.7%; P=0.029) leading to a significant difference in the primary outcome (112 patients [5.6%] in 2019 vs 129 [7.6%] in 2020; P=0.018). No significant difference was observed in rates of orotracheal intubation, in-hospital cardiac arrest, ventricular arrhythmias and cardiogenic shock. CONCLUSIONS: During the first peak of the COVID-19 pandemic in France, there was a decrease in STEMI admissions, associated with longer ischaemic time, exclusively driven by an increase in patient-related delays and an increase in mechanical complications. These findings suggest the need to encourage the population to seek medical help in case of symptoms.

High-sensitivity troponin has become an essential emergency biomarker for diagnosing or ruling out an ACS. The establishment of a point of care biology related to the reorganization and fusion of laboratories raise a question about transferability of results between techniques. In this study, we propose to compare the bioclinical performances of high-sensitivity troponin measured by two different techniques on laboratory immunoanalyzer (Siemens Advia Centaur XPT) and on point of care device (Mitsubishi Pathfast). The assay of high-sensitivity troponin (n = 90 patients), according to our study, show consistent clinical results with both method.

BACKGROUND AND AIMS: Complex aortic atheroma (CAA) is a common cause of acute brain ischemia (BI), including ischemic stroke (IS) and transient ischemic attack (TIA), and is associated with recurrence. The CHA2DS2-VASc score is a useful tool for predicting stroke in patients with atrial fibrillation (AF), and can also predict cardiovascular events in other populations, including non-AF populations. The ADAM-C score is a new risk score for predicting the diagnostic yield of transesophageal echocardiography (TEE) after BI. We aimed to evaluate the ability of CHA2DS2-VASc and ADAM-C scores to predict CAA after BI. METHODS: This prospective, multicenter, observational study included 1479 patients aged over 18 years who were hospitalized for BI. CAA was defined as the presence of one or more of the following criteria: thrombus, ulcerated plaque, or plaque thickening ≥ 4 mm. RESULTS: CAA was diagnosed in 216 patients (14.6%). CHA2DS2-VASc and ADAM-C scores were significantly higher in the CAA group versus the non-CAA group (P < .0001 for both). The CHA2DS2-VASc and ADAM-C scores appear to be good predictors of CAA (AUC 0.699 [0.635, 0.761] and 0.759 [0.702, 0.814], respectively). The sensitivity, specificity, predictive positive value (PPV), and negative predictive value (NPV) of the scores for detecting CAA were 94%, 22%, 17%, and 96%, respectively, for a CHA2DS2-VASc score < 2, and 90%, 46%, 22%, and 96%, respectively, for an ADAM-C score < 3 CONCLUSIONS: CHA2DS2-VASc and ADAM-C scores are able to predict CAA after BI. CHA2DS2-VASc < 2 and ADAM-C < 3 both have an interesting NPV of 96%.
