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
Abstract
Background
In the large randomized trials evaluating patent foramen ovale (PFO) closure vs. medical treatment in secondary prevention of stroke, the incidence of atrial fibrillation has been reported more frequently with PFO closure (2.9–6.6%) than with medical treatment (0.4–1.9%). These episodes were clinically reported and may not reflect the real incidence detected by prolonged ECG recording.
Purpose
To evaluate the incidence and timing of supraventricular tachycardia (SVT) after percutaneous PFO closure.
Methods
Prolonged cardiac monitoring was proposed to patients undergoing PFO closure at the tertiary center of Pitié Salpétrière Hospital, Paris. According to the estimated risk of SVT, two different approaches were used to monitor cardiac rhythm. A 3-year permanent recording using REVEAL™ XT or LINQ was proposed to high risk patients (age >45 years, multiple CV risk factors, prior palpitations or supraventricular ectopic activity during Holter monitoring prior to the intervention). A 4-week, 15-lead ECG continuous recording using the patch-free, wire-free, wearable Cardioskin™ system was proposed to lower risk patients. Endpoints of interest were the occurrence of SVT episodes (>30 seconds) and unplanned medical consultation or hospitalization for this reason
Results
From October 2018 to January 2020, a total of 64 patients underwent prolonged ECG monitoring including 32 (50.0%) and 32 (50.0%) patients with Cardioskin™ and REVEAL™ systems, respectively. A SVT was recorded in 11 (17.4%) patients, including atrial fibrillation (AF) in 6 (9.5%) patients. The median delay of SVT occurrence was 33.0 (14.0–39) days after the procedure (Figure 1) and 18 (10.8–34.8) days for the 6 patients with AF. Unplanned hospitalization or emergency medical visit for symptomatic SVT occurred in 5 (45.5%) patients. Antiarrhythmic medication and oral anticoagulation were initiated in 10 (90.1%) and 7 (63.6%) of the 11 patients, respectively, and SVT recurrences were recorded in 5 (45.5%) patients. No stroke was reported in any of the 11 patients during follow-up. There were no significant differences with respect to baseline and procedural characteristics among patients with or without SVT during follow-up.
Conclusion
Atrial tachycardia is frequent (17.4%) after PFO closure and long-term continuous ECG recording suggests that the incidence is higher than the clinical episodes reported in the randomized trials. This arrhythmic complication of PFO closure seems limited to the first 4 months following the procedure. Larger studies need now to confirm our findings.

Abstract
Abstract
Aims
Out-of-hospital cardiac arrest (OHCA) without return of spontaneous circulation (ROSC) despite conventional resuscitation is common and has poor outcomes. Adding extracorporeal membrane oxygenation (ECMO) to cardiopulmonary resuscitation (extracorporeal-CPR) is increasingly used in an attempt to improve outcomes.
Methods and results
We analysed a prospective registry of 13 191 OHCAs in the Paris region from May 2011 to January 2018. We compared survival at hospital discharge with and without extracorporeal-CPR and identified factors associated with survival in patients given extracorporeal-CPR. Survival was 8% in 525 patients given extracorporeal-CPR and 9% in 12 666 patients given conventional-CPR (P = 0.91). By adjusted multivariate analysis, extracorporeal-CPR was not associated with hospital survival [odds ratio (OR), 1.3; 95% confidence interval (95% CI), 0.8–2.1; P = 0.24]. By conditional logistic regression with matching on a propensity score (including age, sex, occurrence at home, bystander CPR, initial rhythm, collapse-to-CPR time, duration of resuscitation, and ROSC), similar results were found (OR, 0.8; 95% CI, 0.5–1.3; P = 0.41). In the extracorporeal-CPR group, factors associated with hospital survival were initial shockable rhythm (OR, 3.9; 95% CI, 1.5–10.3; P = 0.005), transient ROSC before ECMO (OR, 2.3; 95% CI, 1.1–4.7; P = 0.03), and prehospital ECMO implantation (OR, 2.9; 95% CI, 1.5–5.9; P = 0.002).
Conclusions
In a population-based registry, 4% of OHCAs were treated with extracorporeal-CPR, which was not associated with increased hospital survival. Early ECMO implantation may improve outcomes. The initial rhythm and ROSC may help select patients for extracorporeal-CPR.
