Impact of Physical Activity in Patients With Atrial Fibrillation Undergoing Catheter Ablation: The Multicenter Randomized BE-ACTION Trial.

Background: Arrhythmia recurrence after pulmonary vein isolation (PVI) is common. We conducted a multicenter, randomized trial to determine the impact of increased physical activity on atrial fibrillation recurrence after PVI.

Methods: From 2018 to 2020, we randomly assigned 200 patients with atrial fibrillation to the ACTION or NO-ACTION group in 4 different centers in the local country of Brandenburg, Germany.

Outcome and microbiological findings of patients with cardiac implantable electronic device infection.

Introduction: Infections associated with cardiac implantable electronic devices (CIEDs) are a multifactorial disease that leads to increased morbidity and mortality.

Objective: The aim was to analyze patient-, disease- and treatment-related characteristics including microbiological and bacterial spectrum according to survival status and to identify risk factors for 1- and 3-year mortality in patients with local and systemic CIED infection.

Methods: In a retrospective cohort study, we analyzed data from patients with CIED-related local or systemic infection undergoing successful transvenous lead extraction (TLE).

Patient reported experience and adherence to remote patient management in chronic heart failure patients: a posthoc analysis of the TIM-HF2 trial.

Aims: Remote patient management (RPM) enables early detection and prevention of deterioration in heart failure (HF) patients by measuring vital parameters. The analysis objective is to assess patient reported experience with RPM, adherence to daily measurements, and outline affecting factors both.

Methods And Results: Telemedical interventional management in-HF2 was conducted in 2013-18 with 1 538 HF patients with a 12-month follow-up.

Mortality and morbidity 1 year after stopping a remote patient management intervention: extended follow-up results from the telemedical interventional management in patients with heart failure II (TIM-HF2) randomised trial.

Background: The Telemedical Interventional Management in Heart Failure II (TIM-HF2) trial showed that, compared with usual care, a structured remote patient management (RPM) intervention done over 12-months reduced the percentage of days lost due to unplanned cardiovascular hospitalisations and all-cause death. The aim of the study was to evaluate whether this clinical benefit seen for the RPM group during the initial 12 month follow-up of the TIM-HF2 trial would be sustained 1 year after stopping the RPM intervention.

Methods: TIM-HF2 was a prospective, randomised, multicentre trial done in 43 hospitals, 60 cardiology practices, and 87 general practitioners in Germany.

Heart failure patients with atrial fibrillation benefit from remote patient management: insights from the TIM-HF2 trial.

Aims: Atrial fibrillation (AF) is a frequent comorbidity in patients with heart failure (HF). HF patients with AF are characterized by high morbidity and increased risk of hospitalizations. We assessed the effects of remote patient management (RPM) in HF patients with AF compared with usual care (UC) in the TIM-HF2 trial.

Biomarker guidance allows a more personalized allocation of patients for remote patient management in heart failure: results from the TIM-HF2 trial.

Aims: The TIM-HF2 study showed less days lost due to unplanned cardiovascular hospitalization or all-cause death and improved survival in patients randomly assigned to remote patient management (RPM) instead of standard of care.

Methods And Results: This substudy explored whether the biomarkers mid-regional pro-adrenomedullin (MR-proADM) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) could be used to identify low-risk patients unlikely to benefit from RPM, thereby allowing more efficient allocation of the intervention. For 1538 patients of the trial (median age 73 years, interquartile range 64-78 years, 30% female), baseline biomarkers were used to select subpopulations recommended for RPM with various safety endpoints (100%, 98%, 95% sensitivity), and efficacy of RPM was assessed.

Laparoscopic repositioning of a dislocated pacemaker into the rectovesical pouch.

Dislocation of the epicardial pacemaker into the peritoneal cavity is an uncommon but potentially life-threatening complication. We report a case of a 74 year old with an abdominally implanted epicardial pacemaker that migrated through the peritoneum to the excavatio rectovesicalis. The laparoscopic approach was chosen because of the increased risks of perioperative morbidity and decreased survival.

Predictors of permanent pacemaker implantation after transcatheter aortic valve implantation for aortic stenosis using Medtronic new generation self-expanding CoreValve Evolut R.

Conduction disturbance requiring permanent pacemaker (PPM) implantation is a common complication after transcatheter aortic valve implantation (TAVI) using Medtronic self-expanding CoreValve, and has remained common following the introduction of the new generation CoreValve Evolut R device. The aim of this study was to identify the determinants of PPM implantation after TAVI with CoreValve Evolut R. We retrospectively examined 114 patients who underwent transfemoral TAVI using CoreValve Evolut R.

Prognosis associated with redo cardiac resynchronization therapy following complete device and lead extraction due to device-related infection.

Aims: An increase in the number of cardiac resynchronization therapy (CRT) device implantations worldwide has led to a consequent increase in the number of infections associated with the device, making extraction of the CRT device inevitable. Redo CRT implantation after treatment and recovery following device extraction is challenging. This study aimed to evaluate the success rate, complications, and long-term prognosis of redo CRT implantation, including the rates of subclavian, cava, and coronary sinus (CS) vein thrombosis as well as re-infection.

Jet energy measurement and its systematic uncertainty in proton-proton collisions at [Formula: see text] TeV with the ATLAS detector.

The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector using proton-proton collision data with a centre-of-mass energy of [Formula: see text] TeV corresponding to an integrated luminosity of [Formula: see text][Formula: see text]. Jets are reconstructed from energy deposits forming topological clusters of calorimeter cells using the anti-[Formula: see text] algorithm with distance parameters [Formula: see text] or [Formula: see text], and are calibrated using MC simulations. A residual JES correction is applied to account for differences between data and MC simulations.

A likelihood-based discriminant for the identification of quark- and gluon-initiated jets is built and validated using 4.7 fb[Formula: see text] of proton-proton collision data at [Formula: see text] [Formula: see text] collected with the ATLAS detector at the LHC. Data samples with enriched quark or gluon content are used in the construction and validation of templates of jet properties that are the input to the likelihood-based discriminant.

Measurement of the centrality and pseudorapidity dependence of the integrated elliptic flow in lead-lead collisions at [Formula: see text] TeV with the ATLAS detector.

The integrated elliptic flow of charged particles produced in Pb+Pb collisions at [Formula: see text] TeV has been measured with the ATLAS detector using data collected at the Large Hadron Collider. The anisotropy parameter, [Formula: see text], was measured in the pseudorapidity range [Formula: see text] with the event-plane method.
