Background: Recurrences of atrial fibrillation (AF) after pulmonary vein isolation (PVI) are mainly due to reconnection. However, a growing number patients have AF recurrences despite durable PVI. The optimal ablative strategy for these is unknown. We analyzed the impact current ablation strategies in large multicenter study. Methods: Patients undergoing redo and presenting PVI were included. freedom from arrhythmia vein-based, linear-based, electrogram-based, trigger-based compared....
Right phrenic nerve palsy (PNP) is a usual complication of atrial fibrillation ablation procedures, in particular with cryoballoon1. PNP specific Pulsed Field Ablation either2,3. Several cases persistent were described2,3. It should be noticed that no monitoring was performed these studies, thus incidence could have been underestimated. Moreover, nothing known about the mechanism and mode occurrence this complication. What onset pattern (sudden or progressive)? Is it dose-dependent? Can-it...
Background— Electromyography-guided phrenic nerve (PN) monitoring using a catheter positioned in hepatic vein can aid preventing palsy (PNP) during cryoballoon ablation for atrial fibrillation. We wanted to evaluate the feasibility and efficacy of PN procedures second-generation cryoballoons. Methods Results— This study included 140 patients (43 women) whom pulmonary isolation was performed cryoballoon. by pacing right at 60 per minute recording diaphragmatic compound motor action potential...
We evaluated the age-specific mortality of unselected adult outpatients infected with SARS-CoV-2 treated early in a dedicated COVID-19 day hospital and we assessed whether use hydroxychloroquine (HCQ) + azithromycin (AZ) was associated improved survival this cohort. A retrospective monocentric cohort study conducted our center from March to December 2020 adults PCR-proven infection who were as standardized protocol. The primary endpoint 6-week mortality, secondary endpoints transfer...
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 characteristics survival of transplanted ES. Methods results Patients registered HT waiting list during following days after ES eventually transplanted, from 2010 to 2021, were retrospectively included 11 French centres. The primary endpoint was in-hospital mortality....
Abstract Background and Aims Prophylactic implantable cardioverter–defibrillators (ICDs) are not recommended until left ventricular ejection fraction (LVEF) has been reassessed 40 to 90 days after an acute myocardial infarction. In the current therapeutic era, prognosis of sustained arrhythmias (VAs) occurring during this early post-infarction phase (i.e. within 3 months hospital discharge) yet specifically evaluated in post-myocardial infarction patients with impaired LVEF. Such was aim...
Abstract Introduction The ConfiDENSE™ module (Carto3 v4) allows rapid annotation of endocardial electrograms acquired by multielectrode (ME) mapping. However, its accuracy in assessing atrial voltages is unknown. Methods and results Two left voltage maps were created during continuous pacing 20 patients undergoing catheter ablation for persistent AF using a ME lasso contact force (CF) sensing catheter. automated tissue proximity indicator (TPI) filter was then applied to the map yield TPI...
Reimplantation of cardiac implantable electronic devices (CIEDs) after extraction due to device infection is a major issue in pacemaker-dependent patients. We compared in-hospital and long-term outcomes with two techniques: epicardial reimplantation (EPI) before CIED temporary pacing (TP) view delayed endocardial reimplantation. Two cohorts consecutive patients who underwent transvenous lead at our tertiary centre were included this retrospective cohort study. According successive policies,...
In a recent position paper, the European Heart Rhythm Association (EHRA) proposed an algorithm for screening and management of arrhythmias using digital devices. patients with prior stroke, systematic approach atrial fibrillation (AF) should always be implemented, preferably immediately after event. Patients increasing age specific cardiovascular or non-cardiovascular comorbidities are also deemed to at higher risk. From large nationwide database, aim was analyse AF incidence rates derived...
Background and aims Right phrenic nerve palsy is the most frequent complication of cryoballoon procedures. The SMARTFREEZE™ console (Boston Scientific, St. Paul, MN, USA) has integrated a new tool for diaphragm monitoring—the Diaphragm Movement Sensor; however, it not been evaluated in clinical practice. We aimed to assess diagnostic performance Sensor based on compound motor action potential data recorded simultaneously. Methods Thirty consecutive patients (mean age 63.2 ± 10.2 years) were...
We sought to compare outcomes and costs of a stepwise approach transvenous lead extraction (TLE) involving laser-assisted sheaths or mechanical polypropylene sheaths, with/without crossover. prospectively included patients who underwent TLE (between August 2013 December 2014) as part simple traction, snaring, sheath-assisted dissection; all these first-line polypropylene-sheath-extraction (Group A). The comparison group B) was consecutive had undergone before 2013, during which sheath the...
