Article Synopsis
- Acute heart failure (AHF) patients exhibit a wide range of symptoms and risks, making them a complex group to manage, with increased chances of dangerous ventricular arrhythmias (VAs) during episodes.
- New VAs during AHF correlate with higher morbidity and mortality in hospitals, but there is ongoing debate about when to perform coronary interventions or implant defibrillators.
- Different European countries have varying emergency medical capabilities for treating AHF and VAs, and while guidelines exist for chronic heart failure, less is known about arrhythmias in AHF, prompting this consensus paper to propose better ways to identify and treat these complications.
Background: Post-myocardial infarction (MI) patients with ventricular tachycardia (VT) are considered at risk for VT recurrence and sudden cardiac death (SCD). Recent guidelines indicate that in selected patients catheter ablation should be considered instead of an implantable cardioverter-defibrillator (ICD).
Objectives: This study aimed to analyze outcomes of patients referred for VT ablation according to left ventricular ejection fraction (LVEF), tolerance of VT, and acute ablation outcome.
Characterization of atrial arrhythmias following mitral valve repair: Incidence and risk factors.

Objectives: This study aims to investigate the occurrence, type and correlation of early and late atrial arrhythmias following mitral valve repair in patients with no preoperative history of atrial arrhythmias.
Methods: Patients undergoing mitral valve (MV) repair for degenerative disease were included. Early and late postoperative electrocardiograms were evaluated for the incidence and type of atrial arrhythmia (atrial fibrillation [AF] or atrial tachycardia [AT]).
Validation of a prediction model for early reconnection after cryoballoon ablation.

Background: We previously developed an early reconnection/dormant conduction (ERC) prediction model for cryoballoon ablation to avoid a 30-min waiting period with adenosine infusion. We now aimed to validate this model based on time to isolation, number of unsuccessful cryo-applications, and nadir balloon temperature.
Methods: Consecutive atrial fibrillation patients who underwent their first cryoballoon ablation in 2018-2019 at the Leiden University Medical Center were included.
Aims: Patients with ischaemic cardiomyopathy (ICM) referred for catheter ablation of ventricular tachycardia (VT) are at risk for end-stage heart failure (HF) due to adverse remodelling. Local unipolar voltages (UV) decrease with loss of viable myocardium. A UV parameter reflecting global viable myocardium may predict prognosis.
