Abstract
Abstract
Background
The relations between voltage mapping and diagnosis or genetic background of patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) have not been investigated so far.
Objective
To investigate if diagnosis or genetic background were linked to voltage mapping in ARVC.
Method
97 patients with proved or suspected ARVC undergoing 3D endocardial mapping and genetic testing have been retrospectively included. Presence, localisation and extension of low voltage areas were correlated to ARVC diagnosis and presence of a culprit mutation.
Results
68 patients (70%) fulfilled ARVC diagnosis according to the Task Force criteria and 43 (44%) had ARVC-causal mutations. 78 (80%) presented with some bipolar or unipolar endocardial scar. 60/ 78 patients with endocardial scar (77%) fulfilled the criteria for a definitive ARVC diagnosis versus 8/19 patients without scar (42%) (p=0.003).
In the 68 patients with a definitive diagnosis of ARVC, the presence of endocardial scar was similar whether an ARVC-causal mutation was present or not (35/40 vs 25/28, p=ns). While there was slightly more infero-lateral scars in patients carrying a pathogenic genetic variant (34/40 vs 18/28, p=0.04), there was no difference for right ventricular outflow tract (24/40 vs 17/28) and apical scars (12/40 vs 11/28) or for multiple scars (26/35 vs 14/25 patients with scars). Scar extension was greater in patients with pathogenic variants (bipolar 12±10 vs 6±10%, p=0.02, and unipolar 22±13 vs 12±15%, p=0.01).
Conclusion
3D endocardial mapping could have an important role for refining ARVC diagnosis. Trends for larger and more infero-lateral scars were observed in mutated patients, without difference according to the mutated genes.

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Background
Catheter ablation is frequently needed to treat ventricular tachycardia (VT) in ARVC patients. Ablation aiming non-inducibility (NI) and late potential (LP) abolition has been shown to be effective1. Simultaneous endo-epicardial mapping demonstrate epicardial involvement in most VT2. However epicardial fat and vicinity of coronary artery may prevent effective epicardial ablation.
Aims
(a) evaluate endocardial-only ablation guided by epicardial late-potential recording (EA-ELP) to achieve LP abolition (LPA) and NI; (b) measure ablation-index(AI) values allowing epicardial LP suppression by endocardial ablation, as a surrogate for transmurality.
Methods
From 2019 to 2021 the authors (XW, EG) evaluated EA-ELP in ARVC patients patient referred for ablation. Our ablation protocol was previously described3. Endo and epicardial voltage mapping of the right ventricle (RV) were performed in sinus rhythm using 0.5-1.5 mV threshlods for endocardial scar and 0.5-1 mV for the epicardial. All LP were manually tagged. Programmed ventricular stimulation (PVS) was performed till S4 from the RV apex and other sites, all inducible tolerated VT were mapped. Endocardial ablation was performed with an irrigated tip catheter positioned in front of epi-LP recorded by a multi-electrode catheter aiming to eliminate or delay epi-LP as a surrogate for transmurality. For each lesion fulfilling the «transmurality criteria», the AI values were recorded. Remap was performed to validate LPA and NI was tested. Patient follow-up (FU) rely on telemonitoring in ICD-carriers and holter/exercise test for the others.
Results
11 patients were enrolled (9M/2F, mean age 45 years), 9 for VT recurrence (3 redo) and 2 for de novo VT. The median ICD therapy before ablation was 5/patient (mean 1.7). The clinical VT originated from the RV outflow tract (RVOT) in 5 patients, peritricuspid (PT) in 2, RV free wall (RFW) in 4. Substrate were more extended in the epicardium compared to the endocardium: epi-LP and scar surfaces were 42.5 cm2/118 cm2 versus 24.5 cm2/25.5 cm2 for the endocardium. In one patient, additional epicardial lesion was necessary to achieve LPA. The mean ablation duration was 3377 s. Remap showed LPA in all patients and PVS was negative in all (not tested in one due to hemodynamic instability). One patient presented retrosternal hematoma after ablation with spontaneous favorable outcome. Endocardial AI values allowing epi-LP abolition were 595 for the inferior wall, 625 in the RVOT, 604 for PT and 639 for RFW. During a mean FU of 12 months (median 16.5 mths), only one patient had VT recurrence.
Conclusion
Based on this case-series, EA-ELP appeared as a safe and effective method to treat VT in ARVC. EA-ELP ablation allowed VT suppression in 91 % of patients after an mean FU of 12 mths. The RV endocardial AI needed to suppress epi-LP ranged was between 595-639 and could be used as surrogate for transmurality in ARVC.

Abstract
Hydrostatic pulmonary edema is a well-known complication of veinoarterial extracorporeal membrane oxygenation (VA-ECMO) caused by increased left ventricle afterload due to reverse blood flow in the aorta. Several techniques are commonly used for left ventricle venting such as intra-aortic balloon pump, Impella® (Abiomed, Danvers, MA), central surgical cannulation or Rahskind atrial septostomy. We reported two cases of hydrostatic pulmonary edema in patients under VA-ECMO for whom it was decided to perform Rashkind technique. The first is a late anterior myocardial infarction complicated with cardiac arrest and cardiogenic shock. Refractory hypoxemia due to hydrostatic pulmonary edema conducted us to perform atrial septostomy. The second case is a refractory cardiogenic shock due to left main stent thrombosis myocardial infarction. Procedural transesophageal echocardiography revealed a large left atrial thrombus extended to pulmonary veins preventing the procedure. These two cases illustrate the importance and gravity of pulmonary edema induced by VA-ECMO. The first shows that this technique is feasible, allows great left ventricle unloading and improves hypoxemia. The second underlines the interest of performing transesophageal echocardiography to look for pulmonary veins thrombosis that can take part in the elevation of hydrostatic pressure and forbid Rashkind manoeuver.

Abstract
Abstract
Background
There are only limited options for long-term cardiac monitoring devices readily available in clinical practice for outpatients. Holter monitoring devices are limited by the uncomfort of wires and patches, the small number of leads for analysis, the quality of recordings or the monitoring duration while insertable cardiac monitors are costly and exposed to potential local complication.
Purpose
To describe a single center experience with a novel wearable device for cardiac rhythm monitoring.
Methods
The Cardioskin™ system is a patch-free, wire-free, wearable device with rechargeable batteries that provides a high quality 15-lead electrocardiogram monitoring over 1 month (Figure 1). Data are sent using a mobile application downloaded in the patient smartphone to a central Corelab where they can be interpreted by an expert and/or the prescribing physician. An alarm signal is readily available within the Cardioskin™ device, to allow patients to indicate the presence of symptoms. In this single center retrospective registry, we provide a first report of the use of this novel device in real world practice, with indication and duration of cardiac monitoring left at the physicans “discretion”.
Results
From January 2019 to December 2019, the Cardioskin™ system was prescribed in 60 patients for an overall median duration of 26.5 (14–32) days. The mean age of the patients was 45±12.2 years and 24 (40%) were male. Indications for cardiac monitoring were post-Stroke, palpitation, syncope and cardiomyopathy assessment in 56%, 30%, 7% and 7% of the cases, respectively. A sustained (>30 seconds) supraventricular tachycardia was detected in 4 cases, including one case of atrial fibrillation, two case of atrial tachycardia and on case of junctional tachycardia. Unsustained ventricular tachycardia and atrial fibrillation burst were detected in another 2 cases (Figure 1). There was no reported case of skin irritation by the Cardioskin™ system or abrupt interruption of the monitoring by the patients.
Conclusion
The Cardioskin™ system is a novel, discreet and comfortable cardiac rhythm wearable long-term monitoring device which can be used in clinical practice for broad diagnostic indications.

Introduction
The subcutaneous ICD prevents complications of transvenous leads. Its implantation needs a defibrillation test. Performing this test increases the time of procedures..
Purpose
The aim of our study is to describe the experience of subcutaneous ICD of Assitance Publique des Hopitaux de Paris (AP-HP).
Materials and Methods
In a retrospective cohort we included patients who were involved in subcutaneous ICD treatment at the 5 hospitals of AP-HP from December 2012 to April 2018.Analysis used the Kaplan-Meier method and the Mann-Whitney U test.
Results
162 patients were implanted. 76% of implantations were for secondary prevention before 2017, but only 49% after 2017. 126 (77%) tests were successful at first shock, 14 (8.6%) needed a second shock or more, 9 (5.5%) did not have a test. The shock impedance was significantly higher when the shock was not effective at the first test, 82 ohms CI 95% [68; 112] versus 66 ohms CI 95% [64; 70], p <0.05. 6 patients died (3.7%). Late follow up showed 23 (10%) appropriate shocks and 24 inappropriate shocks (11%) mainly due to T wave oversensing (37.5%).
Conclusions
This is the first french experience of SICD implantation. Success of defibrillation test was lower than expected.

Abstract
BACKGROUND Male hypogonadism, arising from a range of etiologies including androgen-deprivation therapies (ADTs), has been reported as a risk factor for acquired long-QT syndrome (aLQTS) and torsades de pointes (TdP). A full description of the clinical features of aLQTS associated with ADT and of underlying mechanisms is lacking. METHODS We searched the international pharmacovigilance database VigiBase for men (n=6 560 565 individual case safety reports) presenting with aLQTS, TdP, or sudden death associated with ADT. In cardiomyocytes derived from induced pluripotent stem cells from men, we studied electrophysiological effects of ADT and dihydrotestosterone. RESULTS Among subjects receiving ADT in VigiBase, we identified 184 cases of aLQTS (n=168) and/or TdP (n=68; 11% fatal), and 99 with sudden death. Of the 10 ADT drugs examined, 7 had a disproportional association (reporting odds ratio=1.4-4.7; P<0.05) with aLQTS, TdP, or sudden death. The minimum and median times to sudden death were 0.25 and 92 days, respectively. The androgen receptor antagonist enzalutamide was associated with more deaths (5430/31 896 [17%]; P<0.0001) than other ADT used for prostate cancer (4208/52 089 [8.1%]). In induced pluripotent stem cells, acute and chronic enzalutamide (25μM) significantly prolonged action potential durations (action potential duration at 90% when paced at 0.5Hz; 429.7±27.1 (control) versus 982.4±33.2 (acute, P<0.001) and 1062.3±28.9ms (chronic; P<0.001), and generated afterdepolarizations and/or triggered activity in drug-treated cells (11/20 acutely and 8/15 chronically). Enzalutamide acutely and chronically inhibited delayed rectifier potassium current, and chronically enhanced late sodium current. Dihydrotestosterone (30nM) reversed enzalutamide electrophysiological effects on induced pluripotent stem cells. CONCLUSION QT prolongation and TdP are a risk in men receiving enzalutamide and other ADTs. CLINICAL TRIAL REGISTRATION URL: https://www.clinicaltrials.gov. Unique identifier: NCT03193138.

Abstract
Abstract
Aim
Male hypogonadism, arising from various etiologies including androgen-deprivation therapies (ADT), has been reported as a risk-factor for acquired long-QT (aLQT) and Torsades de pointe (TdP). A full description of clinical features of aLQTS associated with ADT and of underlying mechanisms are lacking.
Method and results
We searched the WHO pharmacovigilance database for men (n=6,560,565) presenting with aLQT, TdP or sudden death (SD) associated with ADT. We identified 184 cases of aLQTS and/or TdP (11% fatal), and 99 with SD. Of the 10 ADT examined, 7 had a disproportional association (reporting-OR=1.4–4.7, p<0.05) with aLQT, TdP or SD. The minimum time to SD was 0.25 days. Enzalutamide (Enza, androgen antagonist) was associated with more deaths (17%, p<0.001) than other ADT used for prostate cancer (8.1%,Table). In cardiomyocytes derived from induced pluripotent stem cells (IPS-CMs) from men, we studied electrophysiological effects of enza and dihydrotestosterone (DHT). Acute and chronic enza (25μM) prolonged action potential durations (APD90-paced0.5Hz; 414±63 (control) vs. 951±67 (acute, p<0.01) and 1028±63msec (chronic, p<0.01), and generated early/delayed afterdepolarizations and/or triggered activity in drug treated cells (4/7 acute and 3/5 chronic). Enza acutely and chronically inhibited IKr, and chronically enhanced INa-L. DHT (30nM) reversed enza effects on IPS-CMs. In 7 men with aLQT and hypogonadism, ECGs showed low amplitude, bifid T-waves typical of IKr block which resolved with testosterone.

ADT is a risk factor for aLQT and TdP. Androgens may be useful in TdP treatment of hypogonadic men.

Abstract
Sarcoidosis is a granulomatous disorder of unknown cause characterized by non-caseating granuloma in young adults. Cardiac involvement is rare and range from 2 to 75% depending on diagnostic criteria. Cardiac involvement in sarcoidosis may be asymptomatic or may manifest as rhythm/conduction troubles or congestive heart failure. The diagnosis and treatment of cardiac sarcoidosis may be challenging. However, advances have come in recent years from the use of cardiac MRI and 18FDG-TEP scanner, as well as from the stratification of the risk of ventricular tachycardia/fibrillation. Due to the rarity of the disease, there is no reliable prospective large study to guide therapeutic strategy for cardiac sarcoidosis. Corticosteroids are probably efficacious, in particular in case of atrio-ventricular block or moderate heart failure. Immunosuppressive drugs have not been largely studied but methotrexate could be helpful. In refractory forms, TNF-α antagonists have been used with success.

Abstract
New antithrombotic drugs, antithrombin or anti Xa, will probably be very useful in cardiology. Two directions are interesting: in one hand atrial fibrillation, in which the unmet need concern drugs as effective as vitamine K antagonists but easier to use. On the other hand, in acute coronary syndrome the situation is different, there are many antithrombotic drugs available but there is still a place for innovative drugs which could provide a gain in terms of efficacy, but the hemorrhagic risk must remain acceptable. In atrial fibrillation, the RELY trial, performed in 18,113 patients has demonstrated, as compared to warfarin, a non inferiority of dabigatran at the dose of 110 mg BID and a superiority of dabigatran at 150 mg BID with a reduction of 34% of the primary endpoint, i.e.stroke and systemic embolism.

Abstract
Estrogens are known to activate the phosphatidyl-inosityl 3-kinase (PI3K)/Akt pathway, which is central in the cardioprotection afforded by ischemic postconditioning. Therefore, our goal was to investigate whether a phytoestrogen, genistein, could induce a pharmacological postconditioning and to investigate potential mechanisms. We used low doses of genistein in order to avoid tyrosine kinases inhibition. Thus, pentobarbital-anesthetized rabbits underwent a coronary artery occlusion followed by 4 h of reperfusion. Prior to reperfusion, they randomly received an i.v. injection of either saline (Control), 100 or 1000 microg/kg of genistein (Geni(100) and Geni(1000), respectively), and 10 or 100 microg/kg of 17beta-estradiol (17beta(10) and 17beta(100), respectively). Infarct size (IS, % area at risk) was significantly reduced in Gen(100), Gen(1000) and 17beta(100) but not in 17beta(10) (6+/-2, 16+/-5, 12+/-3 and 29+/-7%, respectively) vs. Control (35+/-4%). A significant decrease in the percentage of TUNEL-positive nuclei within infarcted area was observed in Gen(100) and 17beta(100) vs. Controls. The estrogen receptor antagonist fulvestrant (1 mg/kg i.v.) and the PI3K inhibitor wortmaninn (0.6 mg/kg) abolished the cardioprotective effect of genistein. Western blots also demonstrated an increase in Akt posphorylation in Gen(100). In the same group, in vitro mitochondrial swelling studies demonstrated a significant inhibition of calcium-induced opening of mitochondrial transition pore vs. Controls. In conclusion, genistein exerts pharmacological postconditioning with a similar potency as 17beta-estradiol through a pathway involving activation of the estrogen receptor, of PI3K/Akt and mitochondrial preservation. Therefore, genistein should not be only considered as an inhibitor of tyrosine kinase but also as a cardioprotective estrogen.
