- Abstract
Although rare, iatrogenic aortocoronary dissection is one of the complications most dreaded by the interventional cardiologist. If not managed promptly, it can have redoubted and serious consequences. Herein, we present the case of a 70 year-old woman who was treated by stenting of the second segment of the right coronary artery (RCA) for recurrent angina but, unfortunately, the procedure was complicated by anterograde dissection of the RCA with a simultaneous retrograde propagation to the proximal part of the ascending aorta. Successful stenting of the entry point was able to recuperate the RCA and to limit the retrograde propagation to the ascending aorta, but there was an extension of the dissection to the aortic valve leaflets resulting in a massive aortic insufficiency. Therefore, surgical aortic valve replacement with prosthetic tube graft was performed [corrected].

Circulating microRNAs (miRNA) have been identified as non-invasive biomarkers of cardiac rejection in retrospective studies but their clinical utility has not yet been evaluated in large prospective and unselected cohorts of patients. We designed a longitudinal prospective study (NCT02672683) including 11 heart transplant referral centers. Patients were included from 2016 to 2018. Either de-novo HTx recipients or patients transplanted ≥ 1 year were included at the time of an endomyocardial biopsy (EMB, protocol or for-cause). The primary endpoint was to validate the association between the peripheral expression of 3 previously identified circulating miRNA (miR-10a, miR-92a, and miR-155) with allograft rejection on concomitant EMB. Relative miRNA measurements were performed by normalizing miRNA PCR copy numbers by an endogenous control. A sensitivity analysis was performed by applying an absolute quantification method of microRNA using standard dilution curves of microRNA mimics. The association between miRNA and rejection was tested using mixed effect logistic regression. A total of 461 patients were included representing 831 EMB. Overall, 79 rejection episodes occured, including 25 ACR ≥ 2 R and/or 56 AMR ≥ pAMR 1. In a first pre-specified interim analysis based on 258 EMB from 184 patients including 49 rejection episodes (62% of overall rejections, ACR ≥ 2R = 17, pAMR1(H+) = 14, pAMR1(I+) = 9, pAMR2 = 11), no association between any of circulating miRNA and rejection was found (Figure 1-A). A sensitivity analysis performed with the absolute quantification method on 191 EMB from 134 patients including 94% of overall rejections confirmed those results (Figure 1-B). The analysis of remaining sera was stopped for futility. In this prospective multicenter study of unselected patients, the clinical utility of 3 circulating miRNA as non-invasive biomarkers of cardiac rejection was not confirmed. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Coronary chronic total occlusions (CTO) are frequent, and coronary angioplasty has been increasingly used in recent years for lesion revascularisation. However, to date, no dedicated multicentric prospective study is available in France., Aim: To describe the characteristics of CTO patients and to assess current treatment strategies in French catheterisation laboratory practice., Methods: Patients presenting with CTOs were included from 16/09/2021 to 13/12/2021 over two consecutive prospective phases. In phase I (one month), data were collected to include all patients presenting CTO at diagnostic angiography. In phase II (two months), data were collected focusing on patients who underwent CTO-PCI., Results: A total of 1303 patients (1460 CTOs) were included in 68 French centres. The mean age was 67.7±10.7 years and 84.3% of the patients were men. The prevalence of prior PCI (44.6%), and diabetes mellitus (35.6%) was high. In phase I, multivessel coronary artery disease was detected in two-thirds of cases, and most of them (88.5%) had a single CTO. The mean J-CTO score was 1.9±1.2, with a proportion of difficult and very difficult CTO (J CTO score ≥2) of 61.1%. The selected treatment was medical therapy in 57% of cases, coronary angioplasty in 30% and bypass surgery in 13%. In phase II, 528 patients were included with a mean J-CTO score of 1.8±1.2. Successful guidewire crossing through CTO lesion was obtained with an antegrade access in 89% of patients. Procedural success rate of CTO-PCI was 80%, with a rate of major in-hospital complications of 1% (death: 0.4%, MI: 0.2%, stroke: 0.2%, emergency CABG: 0.2%)., Conclusion: This prospective study provides a snapshot of CTOs prevalence and CTO treatment strategies in France in 2021., (Copyright © 2024 Elsevier Masson SAS.

- Abstract
Background: Previous studies have demonstrated the benefit of a haemodynamic-guided management strategy with the CardioMEMS™ HF System. No data from French patients have been published., Aims: To analyse the feasibility, safety and clinical benefit of the CardioMEMS™ HF System in 103 French patients included in the CardioMEMS HF System Post-Market Study (COAST)., Methods: Prospective open-label cohort of New York Heart Association class III patients with at least one heart failure hospitalization in the 12 months before enrolment, regardless of left ventricular ejection fraction. The primary safety endpoints assessed the freedom from device/system-related complications and from pressure sensor failure at 2 years after implantation. The primary efficacy endpoint was evaluated comparing the rate of heart failure hospitalization during the year before and the year after implantation., Results: At 2 years, there were no device/system-related complications or pressure sensor failures (P<0.0001). There were 179 heart failure hospitalizations in the year before implantation compared with 79 in the year after implantation (risk reduction 50.3%; rate ratio 0.50, 95% confidence interval 0.38-0.66; P<0.0001). During the 2 years of follow-up, pulmonary artery pressures were lowered significantly (mean pulmonary artery pressure -3.7±6.3mmHg; P<0.0001), with a significant improvement in functional class and quality of life., Conclusions: In the French cohort of the COAST study, we have demonstrated that the CardioMEMS™ HF System is a reliable device, with no device/system-related complications or pressure sensor failures. Patients in this open-label cohort had a significant reduction in pulmonary artery pressures, with an improvement in New York Heart Association classification and quality of life, and a 50% reduction in the heart failure hospitalization rate in the year following implantation compared with the previous year., (Copyright © 2024.

- Abstract
Background: Prediction of outcomes remains an unmet need in candidates for LVADs. The development of right-heart failure portends an excess in mortality rates, but imaging parameters of right ventricular systolic function have failed to demonstrate a prognostic role. By integrating pulmonary pressure, right ventriculoarterial coupling could fill this gap., Methods: The ASSIST-ICD registry was used to test right ventriculoarterial coupling as a surrogate parameter at implantation for the prediction of all-cause mortality., Results: The ratio of the tricuspid annular-plane systolic excursion over the estimated systolic pulmonary pressure (TAPSE/sPAP) was not associated with long-term survival in univariate analysis (P = 0.89), nor was the pulmonary artery pulsatility index (PAPi) (P = 0.13). Conversely, the ratio of the right atrial pressure over the pulmonary capillary wedge pressure (RAP/PCWP) was associated with all-cause mortality (P < 0.01). After taking tricuspid regurgitation severity, LVAD indication, LVAD model, age, blood urea nitrogen levels, and pulmonary vascular resistance into account, RAP/PCWP remained associated with survival (HR 1.35 [1.10 - 1.65]; P < 0.01)., Conclusion: Among pre-implant RVAC surrogates, only RAP/PCWP was associated with long-term all-cause mortality in LVAD recipients. This association was independent of established risk factors., (Copyright © 2024 The Author(s). Published by Elsevier Inc. All rights reserved.)

- Abstract
While studies have shown an association between microRNAs and cardiac rejection, the clinical relevance of a preidentified miRNA signature as a noninvasive biomarker has never been assessed in prospective multicentric unselected cohorts. To address this unmet need, we designed a prospective study (NCT02672683) including recipients from 11 centers between August 2016 to March 2018. The objective was to validate the association between 3 previously identified circulating microRNA (10a, 92a, 155) and the histopathological diagnosis of rejection. Both relative and absolute (sensitivity analysis) quantifications of microRNAs were performed. Overall, 461 patients were included (831 biopsies, 79 rejections). A per-protocol interim analysis (258 biopsies, 49 rejections) did not find any association between microRNA and rejection (microRNA 10a: odds ratio (OR) = 1.05, 95% confidence intervals (CI) = 0.87-1.27, p = 0.61; 92a: OR = 0.98, 95%CI = 0.87-1.10, p = 0.68; 155: OR = 0.91, 95%CI = 0.76-1.10, p = 0.33). These results were confirmed in the sensitivity analysis. The analysis of the remaining sera was stopped for futility. This study shows no clinical utility of circulating microRNAs 10a, 92a, and 155 monitoring in heart allograft recipients., (Copyright © 2023 International Society for the Heart and Lung Transplantation.

- Abstract
Aims: The prognostic value of 'high dose' loop diuretics in advanced heart failure outpatients is unclear. We aimed to assess the prognosis associated with loop diuretic dose in ambulatory patients awaiting heart transplantation (HT)., Methods and Results: All ambulatory patients (n = 700, median age 55 years and 70% men) registered on the French national HT waiting list between 1 January 2013 and 31 December 2019 were included. Patients were divided into 'low dose', 'intermediate dose', and 'high dose' loop diuretics corresponding to furosemide equivalent doses of ≤40, 40-250, and >250 mg, respectively. The primary outcome was a combined criterion of waitlist death and urgent HT. N-terminal pro-B-type natriuretic peptide, creatinine levels, pulmonary capillary wedge pressure, and pulmonary pressures gradually increased with higher diuretic dose. At 12 months, the risk of waitlist death/urgent HT was 7.4%, 19.2%, and 25.6% (P = 0.001) for 'low dose', 'intermediate dose', and 'high dose' patients, respectively. When adjusting for confounders, including natriuretic peptides, hepatic, and renal function, the 'high dose' group was associated with increased waitlist mortality or urgent HT [adjusted hazard ratio (HR) 2.23, 1.33 to 3.73; P = 0.002] and a six-fold higher risk of waitlist death (adjusted HR 6.18, 2.16 to 17.72; P < 0.001) when compared with the 'low dose' group. 'Intermediate doses' were not significantly associated with these two outcomes in adjusted models (P > 0.05)., Conclusions: A 'high dose' of loop diuretics is strongly associated with residual congestion and is a predictor of outcome in patients awaiting HT despite adjustment for classical cardiorenal risk factors. This routine variable may be helpful for risk stratification of pre-HT patients., (© 2023 The Authors.

- Abstract
Aims: Heart transplantation (HT) can be proposed as a therapeutic strategy for patients with severe refractory electrical storm (ES). Data in the literature are scarce and based on case reports. We aimed at determining the characteristics and survival of patients transplanted for refractory ES., Methods and Results: Patients registered on HT waiting list during the following days after ES and eventually transplanted, from 2010 to 2021, were retrospectively included in 11 French centres. The primary endpoint was in-hospital mortality. Forty-five patients were included [82% men; 55.0 (47.8-59.3) years old; 42.2% and 26.7% non-ischaemic dilated or ischaemic cardiomyopathies, respectively]. Among them, 42 (93.3%) received amiodarone, 29 received (64.4%) beta blockers, 19 (42.2%) required deep sedation, 22 had (48.9%) mechanical circulatory support, and 9 (20.0%) had radiofrequency catheter ablation. Twenty-two patients (62%) were in cardiogenic shock. Inscription on wait list and transplantation occurred 3.0 (1.0-5.0) days and 9.0 (4.0-14.0) days after ES onset, respectively. After transplantation, 20 patients (44.4%) needed immediate haemodynamic support by extracorporeal membrane oxygenation (ECMO). In-hospital mortality rate was 28.9%. Predictors of in-hospital mortality were serum creatinine/urea levels, need for immediate post-operative ECMO support, post-operative complications, and surgical re-interventions. One-year survival was 68.9%., Conclusion: Electrical storm is a rare indication of HT but may be lifesaving in those patients presenting intractable arrhythmias despite usual care. Most patients can be safely discharged from hospital, although post-operative mortality remains substantial in this context of emergency transplantation. Larger studies are warranted to precisely determine those patients at higher risk of in-hospital mortality., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

- Abstract
Aims: The value of Forrester's perfusion/congestion profiles assessed by invasive catheter evaluation in non-inotrope advanced heart failure patients listed for heart transplant (HT) is unclear. We aimed to assess the value of haemodynamic evaluation according to Forrester's profiles to predict events on the HT waitlist., Methods and Results: All non-inotrope patients (n = 837, 79% ambulatory at listing) registered on the French national HT waiting list between 1 January 2013 and 31 December 2019 with right heart catheterization (RHC) were included. The primary outcome was a combined criteria of waitlist death, delisting for aggravation, urgent HT or left ventricular assist device implantation. Secondary outcome was waitlist death. The 'warm-dry', 'cold-dry', 'warm-wet', and 'cold-wet' profiles represented 27%, 18%, 27%, and 28% of patients, respectively. At 12 months, the respective rates of primary outcome were 15%, 17%, 25%, and 29% (P = 0.008). Taking the 'warm-dry' category as reference, a significant increase in the risk of primary outcome was observed only in the 'wet' categories, irrespectively of 'warm/cold' status: hazard ratios, 1.50; 1.06-2.13; P = 0.024 in 'warm-wet' and 1.77; 1. 25-2.49; P = 0.001 in 'cold-wet'., Conclusions: Haemodynamic assessment of advanced HF patients using perfusion/congestion profiles predicts the risk of the combine endpoint of waitlist death, delisting for aggravation, urgent heart transplantation, or left ventricular assist device implantation. 'Wet' patients had the worst prognosis, independently of perfusion status, thus placing special emphasis on the cardinal prominence of persistent congestion in advanced HF., (© 2022 The Authors.

- Abstract
Objectives: Temporary circulatory support (TCS) as a bridge-to-left ventricular assist device (BTL) in cardiogenic shock patients has been increasing, but limited data exists on this BTL strategy. We aimed at analyzing the outcome of BTL patients in a population of cardiogenic shock patients compared with those without TCS at the time of the left ventricular assist device (LVAD) surgery and identify predictors of postoperative mortality in this specific population., Design: A multicenter retrospective observational study conducted in 19 centers from 2006 to 2016., Setting: Nineteen French centers., Patients: A total of 329 cardiogenic shock patients at the time of LVAD implantation were analyzed. Patients were divided in three groups: those under TCS at the time of LVAD implantation (n = 173), those with TCS removal before LVAD surgery (n = 24), and those who did not undergo a bridging strategy (n = 152). Primary endpoint was 30-day mortality., Interventions: None., Measurements and Main Results: Among the BTL group, 68 (39.3%), 18 (10.4%), and 15 (8.7%) patients were under venoarterial extracorporeal membrane oxygenation, Impella, and IABP support alone, and 72 patients (20.6%) were under multiple TCS support. BTL patients presented similar 30 days survival compared with the TCS removal and non-BTL groups. However, BTL group had a significantly longer ICU duration stay, with two-fold duration of mechanical ventilation time, but the three groups experienced similar postoperative complications. Multivariate analysis identified three independent predictors of mortality in the BTL group: combined surgery with LVAD, body mass index (BMI), and heart failure (HF) duration. BTL strategy was not an independent predictor of mortality in cardiogenic shock patients who underwent LVAD., Conclusions: BTL strategy is not associated with a lower survival among cardiogenic shock patients with LVAD implantation. Predictors of mortality are combined surgery with LVAD, higher BMI, and HF duration., Competing Interests: Drs. Delmas and Gaudard received funding from Abiomed. Drs. Delmas and Blangy received funding from Abbott. Dr. Blangy received funding from Boston and Zoll.

- Abstract
Wait times are associated with mortality on waiting list for transcatheter aortic valve replacement (TAVR). Whether longer wait times are associated with long term mortality after successful TAVR remains unassessed. Consecutive patients successfully treated with elective TAVR in our center between January 2013 and August 2019 were included. The primary end point was one-year all-cause mortality. TAVR wait times were defined as the interval from referral date for valve replacement to the date of TAVR procedure. A total of 383 patients were included with a mean wait time of 144.2 ± 83.87 days. Death occurred in 55 patients (14.4%) at one year. Increased wait times were independently associated with a relative increase of 1-year mortality by 2% per week after referral (Adjusted Hazard Ratio 1.02 [1.002-1.04]; p = 0.02) for TAVR. Chronic kidney disease, left ventricular ejection fraction ≤ 30%, access site and STS score were other independent correlates of 1-year mortality. Our study shows that wait times are relatively long in routine practice and associated with increased 1-year mortality after successful TAVR. Such findings underscore the need of strategies to minimize delays in access to TAVR., (© 2022. The Author(s).)

- Abstract
Background: First medical contact (FMC)-to-balloon time is associated with outcome of ST-elevation myocardial infarction (STEMI). We assessed the impact on mortality and the determinants of indirect vs. direct transfer to the cardiac catheterization laboratory (CCL)., Methods: We analyzed data from 2,206 STEMI patients consecutively included in a prospective multiregional percutaneous coronary intervention (PCI) registry. The primary endpoint was 1-year mortality. The impact of indirect admission to CCL on mortality was assessed using Cox models adjusted on FMC-to-balloon time and covariables unequally distributed between groups. A multivariable logistic regression model assessed determinants of indirect transfer., Results: A total of 359 (16.3%) and 1847 (83.7%) were indirectly and directly admitted for PCI. Indirect admission was associated with higher risk features, different FMCs and suboptimal pre-PCI antithrombotic therapy.At 1-year follow-up, 51 (14.6%) and 137 (7.7%) were dead in the indirect and direct admission groups, respectively (adjusted-HR 1.73; 95% CI 1.22-2.45). The association of indirect admission with mortality was independent of pre-FMC and FMC characteristics. Older age, paramedics- and private physician-FMCs were independent determinants of indirect admission (adjusted-HRs 1.02 per year, 95% CI 1.003-1.03; 5.94, 95% CI 5.94 3.89-9.01; 3.41; 95% CI 1.86-6.2, respectively)., Conclusions: Our study showed that, indirect admission to PCI for STEMI is associated with 1-year mortality independent of FMC to balloon time and should be considered as an indicator of quality of care. Indirect admission is associated with higher-risk features and suboptimal antithrombotic therapy. Older age, paramedics-FMC and self-presentation to a private physician were independently associated with indirect admission. Our study, supports population education especially targeting elderly, more adequately dispatched FMC and improved pre-CCL management., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Beygui, Roule, Ivanes, Dechery, Bizeau, Roussel, Dequenne, Arnould, Combaret, Collet, Commeau, Cayla, Montalescot, Benamer, Motreff, Angoulvant, Marcollet, Chassaing, Blanchart, Koning and Rangé.)

- Abstract
Aims: Despite regularly updated guidelines, there is still a delay in referral of advanced heart failure patients to mechanical circulatory support and transplant centres. We aimed to analyse characteristics and outcome of non-inotrope-dependent patients implanted with a left ventricular assist device (LVAD)., Methods and Results: The ASSIST-ICD registry collected LVAD data in 19 centres in France between February 2006 and December 2016. We used data of patients in Interagency Registry for Mechanically Assisted Circulatory Support Classes 4-7. The primary endpoint was survival analysis. Predictors of mortality were searched with multivariable analyses. A total of 303 patients (mean age 61.0 ± 9.9 years, male sex 86.8%) were included in the present analysis. Ischaemic cardiomyopathy was the leading heart failure aetiology (64%), and bridge to transplantation was the main implantation strategy (56.1%). The overall likelihood of being alive while on LVAD support or having a transplant at 1, 2, 3, and 5 years was 66%, 61.7%, 58.7%, and 55.1%, respectively. Age [hazard ratio (HR) 1.03, 95% confidence interval (CI) 1.00-1.05; P = 0.02], a concomitant procedure (HR 2.32, 95% CI 1.52-3.53; P < 0.0001), and temporary mechanical right ventricular support during LVAD implantation (HR 2.94, 95% CI 1.49-5.77; P = 0.002) were the only independent variables associated with mortality. Heart failure medications before or after LVAD implantation were not associated with survival., Conclusion: Ambulatory heart failure patients displayed unsatisfactory survival rates after LVAD implantation. A better selection of patients who can benefit from LVAD may help improving outcomes., (© 2021 The Authors.

- Abstract
Aim: Due to improved therapy in childhood, many patients with congenital heart disease reach adulthood and are termed adults with congenital heart disease (ACHD). ACHD often develop heart failure (HF) as a consequence of initial palliative surgery or complex anatomy and subsequently require advanced HF therapy. ACHD are usually excluded from trials evaluating heart failure therapies, and in this context, more data about heart failure trajectories in ACHD are needed to guide the management of ACHD suffering from HF., Methods and Results: The pAtients pResenTing with cOngenital heaRt dIseAse Register (ARTORIA-R) will collect data from ACHD evaluated or listed for heart or heart-combined organ transplantation from 16 countries in Europe and the Asia/Pacific region. We plan retrospective collection of data from 1989-2020 and will include patients prospectively. Additional organizations and hospitals in charge of transplantation of ACHD will be asked in the future to contribute data to the register. The primary outcome is the combined endpoint of delisting due to clinical worsening or death on the waiting list. The secondary outcome is delisting due to clinical improvement while on the waiting list. All-cause mortality following transplantation will also be assessed. The data will be entered into an electronic database with access to the investigators participating in the register. All variables of the register reflect key components important for listing of the patients or assessing current HF treatment., Conclusion: The ARTORIA-R will provide robust information on current management and outcomes of adults with congenital heart disease suffering from advanced heart failure., (© 2021 The Authors.

- Abstract
Objectives: We sought to investigate the safety and potential benefit of administrating glycoprotein IIb-IIIa inhibitors (GPIs) on top of more potent P2Y12 inhibitors., Background: A number of clinical trials, performed at a time when pretreatment and potent platelet inhibition was not part of routine clinical practice, have documented clinical benefits of GPI in ST-segment elevation myocardial infarction (STEMI) patients at the cost of a higher risk of bleeding., Methods: We used the data of a prospective, ongoing registry of patients admitted for STEMI in our center. For the purpose of this study only patients presenting for primary percutaneous coronary intervention and pretreated with new P2Y12 inhibitors (prasugrel or ticagrelor) were included. We compared patients who received GPI with those who did not., Results: Eight hundred twenty-four STEMI patients were included in our registry; GPIs were used in 338 patients (41%). GPI patients presented more often with cardiogenic shock and Thrombolysis in myocardial infarction (TIMI) flow grade <3. GPI use was not associated with an increase in in-hospital or 3-month mortality. Bleeding endpoints were similar in both groups., Conclusions: Our study suggests that GPI may be used safely in combination with recent P2Y12 inhibitors in STEMI patients in association with modern primary percutaneous coronary intervention strategies (radial access and anticoagulation with enoxaparin) with similar bleeding and mortality rates at hospital discharge and 3-month follow-up., (© 2021 The Authors.

- Abstract
Background: older patients undergoing percutaneous coronary intervention (PCI) represent a growing population sharing both a high ischemic and bleeding risk. Dual antiplatelet therapy (DAPT) reduces the incidence of thrombotic events but exposes patients to an increased risk of bleeding and subsequent mortality. Its optimal duration after PCI remains unclear., Objective: to assess the impact of short-duration DAPT on both bleeding and ischemic events in the specific population of older patients undergoing PCI., Methods: we performed a meta-analysis of randomised controlled trials comparing the safety and efficacy of standard versus very short duration (≤ 3 months, followed by P2Y12 inhibitor monotherapy) DAPT after PCI with a drug-eluting stent in older patients., Results: four studies, representing 8,961 older patients, were finally included. Compared with standard duration, short-duration DAPT was associated with similar rates of major bleeding (relative risks, RR 0.70 [0.47; 1.05]) and the composite efficacy endpoint (RR 0.85 [0.63; 1.14]). There was a high level of heterogeneity between the studies (I2 = 68%) regarding major bleeding., Conclusion: our meta-analysis suggests that short DAPT may be a valid option in older patients after PCI but it also highlights the need for specific studies in such patients on optimal duration of antiplatelet therapy., (© The Author(s) 2021.

- Abstract
LVAD implantation in patients with a recently diagnosed cardiomyopathy has been poorly investigated. This work aims at describing the characteristics and outcomes of patients receiving a LVAD within 30 days following the diagnosis of cardiomyopathy. Patients from the ASSIST-ICD study was divided into recently and remotely diagnosed cardiomyopathy based on the time from initial diagnosis of cardiomyopathy to LVAD implantation using the cut point of 30 days. The primary end point of the study was all-cause mortality at 30-day and during follow-up. A total of 652 patients were included and followed during a median time of 9.1 (2.5 to 22.1) months. In this population, 117 (17.9%) had a recently diagnosed cardiomyopathy and had LVAD implantation after a median time of 15.0 (9.0 to 24.0) days following the diagnosis. This group of patients was significantly younger, with more ischemic cardiomyopathy, more sudden cardiac arrest (SCA) events at the time of the diagnosis and were more likely to receive temporary mechanical support before LVAD compared with the remotely diagnosed group. Postoperative in-hospital survival was similar in groups, but recently diagnosed patients had a better long-term survival after hospital discharge. SCA before LVAD and any cardiac surgery combined with LVAD implantation were identified as 2 independent predictors of postoperative mortality in recently diagnosed patients. In conclusion, rescue LVAD implantation for recently diagnosed severe cardiomyopathy is common in clinical practice. Such patients experience a relatively low postoperative mortality and have a better long-term survival compared with remotely diagnosed patients., (Copyright © 2021 Elsevier Inc.

- Abstract
Background: The evidence of a clinical benefit of P2Y12 inhibitor pre-treatment in primary percutaneous coronary intervention (PCI) and the relation between the level of platelet inhibition and myocardial reperfusion with newer potent P2Y12 inhibitors remain unclear. We aimed to assess the relationship between platelet reactivity at the time of primary PCI after pre-treatment with aspirin and ticagrelor and the post-PCI myocardial blush grade (MBG)., Methods: We prospectively included 61 patients. Platelet reaction units for ticagrelor (PRU) and aspirin reaction units (ARU) were measured using the point-of-care test VerifyNow before PCI. The high on-ticagrelor (PRU >208) and on-aspirin (ARU ⩾ 550) platelet reactivity (HPR and HaPR) were assessed. Patients were divided into two groups according to MBG 3 or <3., Results: MBG 3 was identified in 28 (46%) patients. Mean PRU was lower in such patients as compared with those with MBG <3 (155.82 ± 90.91 vs . 227.42 ± 65.18; p =0.001) while mean ARU was similar between groups. HPR and HaPR were observed in 30 (49.2%) and 11 patients (18%), respectively. HPR but not HaPR was more frequent in the group with impaired MBG (66.7 vs . 28.6%; p =0.003 and 21.2 vs. 14.3%; p =0.48 respectively)., Conclusion: Our study shows that higher PRU and the subsequent HPR at the time of primary PCI, after pretreatment with ticagrelor, are the only correlates of post PCI MBG. These findings support the earliest possible loading with ticagrelor prior to primary PCI., (© The European Society of Cardiology 2019.)

- Abstract
Background: Percutaneous coronary intervention (PCI)-related myonecrosis is frequent and can affect the long-term prognosis of patients. To our knowledge, ticagrelor has not been evaluated in elective PCI and could reduce periprocedural ischaemic complications compared with clopidogrel, the currently recommended treatment. The aim of the ALPHEUS study was to examine if ticagrelor was superior to clopidogrel in reducing periprocedural myocardial necrosis in stable coronary patients undergoing high-risk elective PCI., Methods: The ALPHEUS study, a phase 3b, randomised, open-label trial, was done at 49 hospitals in France and Czech Republic. Patients with stable coronary artery disease were eligible for the study if they had an indication for PCI and at least one high-risk characteristic. Eligible patients were randomly assigned (1:1) to either ticagrelor (180 mg loading dose, 90 mg twice daily thereafter for 30 days) or clopidogrel (300-600 mg loading dose, 75 mg daily thereafter for 30 days) by use of an interactive web response system, and stratified by centre. The primary outcome was a composite of PCI-related type 4 (a or b) myocardial infarction or major myocardial injury and the primary safety outcome was major bleeding, both of which were evaluated within 48 h of PCI (or at hospital discharge if earlier). The primary analysis was based on all events that occurred in the intention-to-treat population. The trial was registered with ClinicalTrials.gov, NCT02617290., Findings: Between Jan 9, 2017, and May 28, 2020, 1910 patients were randomly assigned at 49 sites, 956 to the ticagrelor group and 954 to the clopidogrel group. 15 patients were excluded from the ticagrelor group and 12 from the clopidogrel group. At 48 h, the primary outcome was observed in 334 (35%) of 941 patients in the ticagrelor group and 341 (36%) of 942 patients in the clopidogrel group (odds ratio [OR] 0·97, 95% CI 0·80-1·17; p=0·75). The primary safety outcome did not differ between the two groups, but minor bleeding events were more frequently observed with ticagrelor than clopidogrel at 30 days (105 [11%] of 941 patients in the ticagrelor group vs 71 [8%] of 942 patients in the clopidogrel group; OR 1·54, 95% CI 1·12-2·11; p=0·0070)., Interpretation: Ticagrelor was not superior to clopidogrel in reducing periprocedural myocardial necrosis after elective PCI and did not cause an increase in major bleeding, but did increase the rate of minor bleeding at 30 days. These results support the use of clopidogrel as the standard of care for elective PCI., Funding: ACTION Study Group and AstraZeneca., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

- Abstract
We compared residual platelet reactivity and post PCI atherothrombotic burden using OFDI in patients successfully treated by primary PCI versus pharmacoinvasive approach (PI) defined as PCI after successful pre-hospital fibrinolysis. Despite pre-hospital P2Y12-inhibitor loading dose, high rates of high on-treatment platelet reactivity were found at the time of PCI in both groups. Primary PCI patients had higher post stenting thrombus burden and lower rates of final normal myocardial blush grade compared to PI. These findings support the use of a pharmacoinvasive reperfusion strategy especially when primary PCI cannot be timely performed.

- Abstract
Background: Implantable cardioverter-defibrillator (ICD) lead dysfunction has been reported after left ventricular assist device (LVAD) implantation in limited single-center studies. We aimed at describing and characterizing the incidence of ICD lead parameters dysfunction after LVAD implantation., Methods: Among the 652 patients enrolled in the ASSIST-ICD study, only patients with an ICD prior to LVAD were included (n = 401). ICD lead parameters dysfunction following LVAD implantation is defined as follows: (a) >50% decrease in sensing threshold, (b) pacing lead impedance increase/decrease by >100Ω, and (c) >50% increase in pacing threshold., Results: One hundred twenty-two patients with an ICD prior to LVAD had available ICD interrogation reports prior and after LVAD. A total of 67 (55%) patients exhibited at least one significant lead dysfunction: 17 (15%) exhibited >50% decrease in right ventricular (RV) sensing, 51 (42%) had >100 Ω increase/decrease in RV pacing impedance, and 24 (20%) experienced >50% increase in RV pacing threshold. A total of 52 patients experienced ventricular arrhythmia during follow-up and all were successfully detected and treated by the device. All lead dysfunction could be managed conservatively., Conclusion: More than 50% of LVAD-recipients may experience >1 significant change in lead parameters but none had severe clinical consequences., (© 2020 Wiley Periodicals LLC.)

- Abstract
We aimed at characterizing the impact of low and high body mass index (BMI) on outcomes after left-ventricular assist device (LVAD) surgery and define the predictors of mortality in patients with abnormal BMI (low/high). This study was conducted in 19 centers from 2006 to 2016. Patients were divided based on their baseline BMI into 3 groups of BMI: low (BMI ≤18.5 kg/m²); normal (BMI = 18.5 to 24.99 kg/m²) and high (BMI ≥25 kg/m²) (including overweight (BMI = 25 to 29.99 kg/m²), and obesity (BMI ≥30 Kg/m²)). Among 652 patients, 29 (4.4%), 279 (42.8%) and 344 (52.8%) had a low-, normal-, and high BMI, respectively. Patients with high BMI were significantly more likely men, with more co-morbidities and more history of ventricular/supra-ventricular arrhythmias before LVAD implantation. Patients with abnormal BMI had significantly lower survival than those with normal BMI. Notably, those with low BMI experienced the worst survival whereas overweight or obese patients had similar survival. Four predictors of mortality for LVAD candidates with abnormal BMI were defined: total bilirubin ≥16 µmol/L before LVAD, hypertension, destination therapy, and cardiac surgery with LVAD. Depending on the number of predictor per patients, those with abnormal BMI may be divided in 3 groups of 1-year mortality risk, i.e., low (0 to 1 predictor: 29% and 31%), intermediate (2 to 3 predictors, 51% and 52%, respectively), and high (4 predictors: 83%). In conclusion, LVAD recipients with abnormal BMI experience lower survival, especially underweight patients. Four predictors of mortality have been identified for LVAD population with abnormal BMI, differentiating those a low-, intermediate-, and high risks of death., (Copyright © 2020 Elsevier Inc.

Objectives: We aimed to assess the relationship between residual in-stent atherothrombotic burden (ATB) after primary percutaneous coronary intervention (PCI) measured by optical frequency domain imaging (OFDI) using different measurement methods and myocardial blush grade (MBG)., Background: The impact of residual ATB after primary PCI on myocardial reperfusion remains unclear., Methods: We prospectively included 60 ST-elevation myocardial infarction patients pretreated with aspirin and ticagrelor. OFDI volumetric quantification using planimetry (with intervals every frame or every millimeter) and semiquantitative score were used to determine ATB. Patients were divided into two groups according to final MBG 3 or <3., Results: The mean ATB was 10.08 ± 5.21%. ATB was lower in patients with final MBG 3 compared to those with impaired MBG, regardless of the measurement method (8.15 ± 5.58 vs. 11.77 ± 4.28%; p = .007 for quantification per frame; 7.8 ± 5.19 vs. 11.07 ± 4.07%; p = .009 for quantification per mm and 11.21 ± 11.75 vs. 22.91 ± 17.35; p = .003 for the semiquantitative thrombus score, respectively)., Conclusion: Residual post-stenting ATB remains substantial after primary PCI in STEMI patients, even when pretreated with ticagrelor and aspirin. ATB appears as a significant correlate of suboptimal myocardial reperfusion, a known surrogate of clinical outcome., (© 2019 Wiley Periodicals, Inc.)

- Abstract
Objectives: We aimed to assess the quality of optical frequency domain imaging (OFDI) of the left main (LM) arterial wall and describe and analyse potential artefacts in this setting., Background: OFDI is increasingly used to assess ambiguous lesions and optimize LM percutaneous coronary intervention. However, its ability to provide artefact-free high-quality images of coronary ostia and large segments such as the LM remains uncertain., Methods: We included 42 consecutive patients who underwent OFDI, including LM imaging. Each OFDI frame was subdivided into four quadrants and analysed. The number of quadrants with artifacts was calculated within the proximal, mid, and distal LM and the first 5 mm of the left anterior descending artery (LAD) and/or left circumflex artery (LCX)., Results: The quadrants analysis showed an overall artifact rate of 8.9%, mostly out-of-field (45.1%) or residual blood (44.7%) artefacts. Most artifacts were located in the proximal LM (18.6%) with a stepwise reduction of artifact rates towards distal segments (mid LM 5.8%; distal LM 3.6%, ostial LAD 2.6%, and ostial LCX 0%; p < 0.001). While 20 (48.8%) patients had angiographically visible plaques, OFDI showed plaques in 32 patients (76.2%; p =0.007)., Conclusion: OFDI can accurately evaluate the LM and detect and assess angiographically unvisualized atherosclerotic plaques providing accurate assessment of >90% of the quadrants of the LM and the ostia of its bifurcation branches. However, artifacts mainly located in the proximal LM and decreasing distally in a stepwise fashion should be considered in the interpretation of OFDI in this setting., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2020 Vincent Roule et al.)

- Abstract
Aims: The aim of this study is to evaluate the usefulness of a personalized discharge checklist (PCL) based on simple baseline characteristics on mortality, readmission for heart failure (HF), and quality of care in patients hospitalized for acute HF., Methods and Results: We designed an algorithm to generate PCL, based on 2016 HF European Society of Cardiology Guidelines and the screening of common comorbidities in elderly HF patients. We prospectively included 139 patients hospitalized for HF from May 2018 to October 2018. A PCL was fulfilled for each patient at admission and 24 to 48 hours before the planned discharge. A control cohort of 182 consecutive patients was retrospectively included from May 2017 to October 2017. The primary composite endpoint was mortality or readmission for HF at 6 months. The secondary endpoints were mortality, readmission for HF, and quality of care (evidence-based medications, management of HF comorbidities, and planned care plan). There was no difference among baseline characteristics between PCL and control cohorts; mean age was 78.1 ± 12.2 vs. 79.0 ± 12.5 years old (P = 0.46) and 61 patients (43.9%) vs. 63 (34.6%) had HF with left ventricular ejection fraction (LVEF) <40% (P = 0.24). During the 6 month follow-up period, 59 patients (42.4%) reached the primary endpoint in the PCL cohort vs. 92 patients (50.5%) in the control cohort [hazard ratio (HR): 0.79, 95% confidence interval (CI) (0.57-1.09), P = 0.15]. Subgroup analysis including only patients with either altered (<40%) or mid-range or preserved (≥40%) LVEF showed no significant difference among groups. There was a non-significant trend toward a reduction in HF readmission rate in the PCL group [38 patients (27.3%) vs. 64 patients (35.2%), HR: 0.73, 95%CI (0.49-1.09), P = 0.13]. There was no difference regarding survival or the use of evidence-based medications. A higher proportion of patients were screened and treated for iron and vitamin D deficiencies (53.2% vs. 35.7%, P < 0.01 and 73.4% vs. 29.7%, P < 0.01, respectively), as well as malnutrition supplemented in the PCL group. There was a higher referral to HF follow-up programme in the PCL group but not to telemedicine or cardiac rehabilitation programs., Conclusions: In this preliminary study, the use of a PCL did not improve outcomes at 6 months in patients hospitalized for acute HF. There was a non-significant trend towards a reduction in HF readmission rate in the PCL group. In addition, the management of HF comorbidities was significantly improved by PCL with a better referral to follow-up programme. A multicentre study is warranted to assess the usefulness of a simple costless personalized checklist in a large HF patients' population., (© 2020 The Authors.

- Abstract
Objectives: To compare three FFR technologies: the electric-sensor Pressurewire® (P), the optic-sensor Comet® (C) guidewire, and the optic-sensor Navvus® (N) microcatheter., Background: Different technologies are used to measure fractional flow reserve (FFR) for the functional assessment of coronary lesions with potential discrepancies., Methods: Sixty-six FFR measurements performed on 32 lesions using each technology were used for a paired comparison of FFR on simultaneous measurements and in clinically relevant conditions (guidewires alone, N on a guidewire)., Results: Simultaneous measurements of FFR were significantly (p < .0001) correlated between systems (ρ = 0.88, 0.81 and 0.86 for P and N, P and C and, C and N, respectively). The presence of the N microcatheter, led to reduced values of FFR measured by P or C guidewires (p < .0001). The concomitant presence of P and C guidewires led to significantly lower FFR values (p < .0001) measured by P but not by C. In clinically relevant conditions, values of FFR measured by the optic-sensor C guidewire and N catheter were similar and lower than those measured by the P guidewire (p < .0001). The agreement between the three technologies (FFR ≤ 0.80) was 94%., Conclusions: FFR values simultaneously measured by three different technologies, are strongly correlated, and provide strongly concordant results. However, significant differences are found between values of FFR. The presence of N, but also C lead to a decrease of FFR measured by P. In clinically relevant conditions, the two optic-sensor technologies provide similar FFR measurements, lower than those measured by the piezo-electric technology suggesting a sensor-technology-related measurement variability., Clinical Trial Registration: NCT#03052803., (© 2019 Wiley Periodicals, Inc.)

- Abstract
The impact of uncommon etiology cardiomyopathies on Left-ventricular assist device (LVAD)-recipient outcomes is not very well known. This study aimed to characterize patients with uncommon cardiomyopathy etiologies and examine the outcomes between uncommon and ischemic/idiopathic dilated cardiomyopathy. This observational study was conducted in 19 centers between 2006 and 2016. Baseline characteristics and outcomes of patients with uncommon etiology were compared to patients with idiopathic dilated/ischemic cardiomyopathies. Among 652 LVAD-recipients included, a total of 590 (90.5%) patients were classified as ischemic/idiopathic and 62 (9.5%) patients were classified in the "uncommon etiologies" group. Main uncommon etiologies were: hypertrophic (n = 12(19%)); cancer therapeutics-related cardiac dysfunction (CTRCD) (n = 12(19%)); myocarditis (n = 11(18%)); valvulopathy (n = 9(15%)) and others (n = 18(29%)). Patients with uncommon etiologies were significantly younger with more female and presented less co-morbidities. Additionally, patients with uncommon cardiomyopathies were less implanted as destination therapy compared with ischemic/idiopathic group (29% vs 38.8%). During a follow-up period of 9.1 months, both groups experienced similar survival. However, subgroup of hypertrophic/valvular cardiomyopathies and CTRCD had significantly higher mortality compared to the ischemic/idiopathic or myocarditis/others cardiomyopathies. Conversely, patients with myocarditis/others etiologies experienced a better survival. Indeed, the 12-months survival in the myocarditis/others; ischemic/idiopathic and hypertrophic/CTRCD/valvulopathy group were 77%; 65%, and 46% respectively. In conclusion, LVAD-recipients with hypertrophic cardiomyopathy, valvular heart disease and CTRCD experienced the higher mortality rate., (Copyright © 2020 Elsevier Inc. All rights reserved.)

- Abstract
Background: Patients with cancer admitted for an acute coronary syndrome (ACS) and/or percutaneous coronary intervention (PCI) represent a growing and high-risk population. The influence of co-existing cancer on mortality remains unclear in such patients. We aimed to assess the impact of cancer on early and late, all-cause and cardiac mortality in the setting of ACS and/or PCI., Methods: We performed a systematic review and meta-analysis of studies comparing outcomes of patients with and without a history of cancer admitted for ACS and/or PCI., Results: Six studies including 294,528 ACS patients and three studies including 39,973 PCI patients were selected for our meta-analysis. Patients with cancer had increased rates of in-hospital all-cause death (RR 1.74 [1.22; 2.47]), cardiac death (RR 2.44 [1.73; 3.44]) and bleeding (RR 1.64 [1.35; 1.98]) as well as one-year all-cause death (RR 2.62 [1.2; 5.73]) and cardiac death (RR 1.89 [1.25; 2.86]) in ACS studies. Rates of long term all-cause (RR 1.96 [1.52; 2.53]) but not cardiac death were higher in cancer patients admitted for PCI., Conclusion: Cancer patients represent a high-risk population both in the acute phase and at long-term after an ACS or PCI. The magnitude of the risk of mortality should however be tempered by the heterogeneity among studies. Early and long term optimal management of such patients should be promoted in clinical practice.

- Abstract
Objective: We investigated whether mental status assessed by simple bedside tests in elderly patients admitted for acute coronary syndromes (ACS) was associated with higher risk of mortality., Methods: We used the data from a prospective, open, ongoing cohort of patients≥75 years old admitted for ACS to a tertiary centre. Cognitive impairment (CogI) was defined by delirium detected by the Confusion Assessment Method or an abnormal Mini Mental State Examination score. A Cox model adjusted on predefined correlates of mortality was used to assess the relationship between CogI and 1-year mortality., Results: Six-hundred consecutive patients with mental status assessment within 48 hours after admission were included. CogI was identified in 172 (29%) patients among whom 153 (25.5%) had an abnormal Mini Mental State Evaluation and 19 (3.2%) delirium. Death occurred in 49 (28.6%) patients with and 43 (10.5%) patients without CogI at 1 year. There was a significant association between CogI and 1-year mortality (adjusted-HR 2.4, 95% CI 1.53 to 3.62), p<0.001) independent of other covariables. CogI was also independently associated with higher rates of in-hospital bleeding and mortality as well as 3-month rates of all-cause, cardiovascular-related and heart failure-related rehospitalisation., Conclusions: CogI detected by simple bedside tests in patients≥75 admitted for ACS is associated with an increased risk of 1-year mortality and 3 month rehospitalisation independent of other correlates of poor outcome., Competing Interests: Competing interests: Thelogistics and management of our cohorts are supported by grants from Biosensors, Medtronic and Boston Scientific., (© Author(s) (or their employer(s)) 2019.

- Abstract
Background: The combination of vitamin K antagonists (VKA) for atrial fibrillation (AF) and antiplatelet agents following percutaneous coronary intervention (PCI) is associated with an increased bleeding risk., Hypothesis: Direct oral anticoagulants (DOAC) are associated with a greater safety profile but the optimal antithrombotic treatment strategy, especially when considering ischemic events, is unclear., Methods: We performed a meta-analysis of randomized controlled trials comparing outcomes in AF patients following PCI and/or acute coronary syndrome (ACS) when treated with DOAC vs VKA, both in combination with one (dual) or two (triple) antiplatelet regimens. A systematic review was performed by searches of electronic databases MEDLINE (source PubMed) and the Cochrane Controlled Clinical Trials Register Database as well as Cardiology annual meetings. Three studies were finally included., Results: Compared to VKA triple therapy, the use of DOAC was associated with a decreased risk of any bleeding (relative risk [RR] 0.68 [0.62; 0.74]), major bleeding (RR 0.61 [0.51; 0.75]) and intracranial bleeding (RR 0.33 [0.17; 0.66]) and similar rates of the composite efficacy endpoint (RR 1.0 [0.87; 1.14]) and its components. Similar and consistent results were observed with both dual and triple therapy including a DOAC compared to VKA., Conclusion: Our meta-analysis supports the use of dual therapy combining a DOAC and clopidogrel as the default regimen in most AF patients after PCI and/or ACS., (© 2019 The Authors.

Background: The use of a discharge checklist may decrease heart failure readmission rate., Aims: We aimed to evaluate the usefulness of a checklist in patients hospitalized for heart failure, in terms of mortality, cardiovascular mortality and readmission rates, and quality of care, including therapeutic optimization and careplan planning., Methods: We prospectively used a discharge checklist in 103 patients hospitalized for heart failure between July 2015 and January 2016. Quality of care and outcomes were compared with a retrospective cohort of 137 patients with same inclusion criteria, hospitalized between June 2014 and December 2014. The primary endpoints were total and cardiovascular mortality and readmissions for heart failure at 6months. The secondary endpoint was quality of care rendered, measured by evidence-based medications, appropriate medication uptitration and planned discharge care., Results: At 6months, there were no differences between the checklist and control cohorts in the rates of all-cause mortality (10.7% vs. 13.1%; P=0.57), cardiovascular mortality (8.7% vs. 10.9%; P=0.58) and readmission (29.1% vs. 32.1%; P=0.62). Follow-up after discharge was better planned in the checklist group. The use of the checklist yielded therapeutic optimization with a higher dose of beta-blockers and renin-angiotensin-aldosterone system blockers, especially in patients with a reduced left ventricular ejection fraction (<50%) (P=0.03 and P=0.02, respectively)., Conclusions: The use of a simple discharge checklist in patients with acute heart failure showed no benefit in terms of readmission and mortality rates; however, it yielded better quality of care, including therapeutic optimization and careplan planning., (Copyright © 2019 Elsevier Masson SAS.

- Abstract
Heart failure (HF) is an increasing pandemic affecting more than 26 million people worldwide. Despite growing therapeutic options, the outlook of patients with HF remains particularly poor with high mortality and rehospitalization rates. When HF remains uncontrolled despite optimal medical therapy, mechanical circulatory devices or heart transplantation must be considered. Unfortunately, these therapeutic options are limited. This case explains how consecutive minimally invasive treatment allowed stabilization of end-stage HF thereby avoiding heart transplantation or mechanical assist devices.

- Abstract
Intracoronary thrombus burden affects the quality of myocardial reperfusion in the setting of ST-elevation myocardial infarction (STEMI). We aimed to study the characteristics of the plaque and thrombus assessed by intracoronary optical frequency domain imaging (OFDI) according to the presence of plaque rupture or erosion in STEMI patients treated with successful fibrinolysis. Pre-stenting thrombus and post-stenting atherothrombotic burden were compared between plaque rupture and erosion. Twenty-seven consecutive patients were included: 17 (63%) had OFDI-plaque rupture and 10 (37%) had OFDI-erosion. Thrombus volume and burden were significantly higher in case of rupture compared to erosion at baseline (13.4 ± 18.4 vs 2.8 ± 2.3 mm
3 ; p = 0.03 and 33.8 ± 17.5 vs 17.5 ± 9.9%; p = 0.007, respectively). In the rupture group, the core of the thrombus consisted dominantly of red thrombus evenly distributed along the entire culprit plaque. In the erosion group, it consisted dominantly of white thrombus with a focal distribution near the minimal lumen area zone. After stenting, the atherothrombotic volume, burden and its distribution, as well as angiographic estimators of myocardial reperfusion were similar between groups. Our study showed that pre-PCI thrombus amount, typesetting and distribution are mainly linked to the underlying mechanism of STEMI. After stenting, the atherothrombotic burden and its distribution were similar between the groups.- Published

- Abstract
Detection of high on-treatment platelet reactivity (HPR) by point-of-care tests has not been validated after successful fibrinolysis for ST-elevation myocardial infarction. We assessed the validity of the point-of-care VerifyNow P2Y12 (VN) and INNOVANCE PFA P2Y (PFA) tests on HPR compared to light transmittance aggregometry (LTA) in these patients. The HPR was identified in 10 (34.5%) patients, 15 (51.7%) patients, and 14 (50%) patients using LTA, VN, and PFA, respectively. Discrepancies were observed between the tests despite significant correlations between platelet reactivity measures by LTA and VN ( r = 0.74; P < .0001) and LTA and PFA ( r = .75; P < .0001). Compared to LTA, VN and PFA were associated with a 92% and 53% and 92% and 64% positive predictive value (PPV) and negative predictive value (NPV), respectively, in detecting HPR. When combined, VN and PFA results yielded 90% and 100% PPV and NPV values if discrepancies between the 2 tests were considered as non-HPR. The VN or PFA identify patients without HPR correctly but overestimate the proportion of HPR patients. The association of the 2 tests, in case of HPR, improves the accuracy of the detection of HPR.

- Abstract
A 45-year-old female was admitted for a transient anterior ST-segment elevation myocardial infarction (STEMI). Coronary angiogram showed a diffuse severe stenosis of the distal left anterior descending (LAD) coronary artery, which was managed medically. Three years later, a recurrent transient anterior STEMI led to a second coronary angiography showing a tubular stenosis of the mid-LAD with normal distal coronary bed. An optical coherence tomography (OCT) revealed a spontaneous coronary artery dissection (SCAD) with an extensive compressive mural hematoma without any intimal tear. Conservative treatment was continued. A repeat systematic angiogram 3months later suggested spontaneous healing but the OCT revealed several focal residual hematomas. This case illustrates the different possible angiographic appearances of SCAD and the contribution of the OCT in doubtful situations., (Copyright © 2017 Elsevier Inc. All rights reserved.)

- Abstract
Background: Patients over 75 account for more than one third of those presenting with myocardial infarction and more than 50% of intrahospital mortality. There are no specific guidelines for the management of acute coronary syndromes (ACS) in the elderly., Setting: Although antithrombotic therapy seems to be effective and safe in such patients, it requires specific precautions and treatment adjustments because of the higher bleeding risk due to comorbidities such as renal function impairment and malnutrition., Results: Scientific evidence concerning elderly patients is scarce as they are either excluded or underrepresented in most randomized trials. Overall, the antithrombotic therapy needs to be adapted to avoid complications, mainly bleeding complications, without compromising the effectiveness of the treatment in this high-risk population., Conclusion: In the present paper, we review the current treatment strategies in ACS while focusing on data concerning the elderly, according to available data in pivotal trials and in both AHA/ACC and ESC guidelines.
