Aims: There is a lack of data from randomized clinical trials comparing treatment outcomes between conduction system pacing (CSP) modalities and biventricular pacing (BVP) in symptomatic patients with refractory atrial fibrillation (AF) scheduled for atrioventricular node ablation (AVNA). The CONDUCT-AF investigates whether CSP is non-inferior to BVP in improving left ventricular ejection fraction (LVEF) and clinical outcomes in heart failure (HF) patients with symptomatic AF undergoing AVNA.
Methods: This study is an investigator-initiated, prospective, randomized, multicentre clinical trial conducted across 10 European centres, enrolling 82 patients with symptomatic AF, HF with reduced LVEF, and narrow QRS.

We present a case of a 71-year-old woman with symptomatic paroxysmal atrial fibrillation and atypical atrial flutter (AFL), ultimately diagnosed with a rare type 3 macro-re-entrant biatrial tachycardia (BiAT). Despite initial pulmonary vein isolation and anterior line ablation for atypical AFL, she experienced recurrent AFL requiring a complex redo ablation. Successful termination of the tachycardia was achieved by extending ablation to the septal regions of both atria.

Background: Pulsed electric field ablation (PFA) techniques for treating cardiac arrhythmias have attracted considerable interest. For example, atrial fibrillation can be effectively treated by pulmonary vein isolation using PFA. However, some arrhythmias originate deep within the myocardium, making them difficult to reach with conventional ablation methods.

Background: Cardiac amyloidosis (CA) is characterized by atrial myopathy, which predisposes patients to atrial fibrillation (AF) and other atrial arrhythmias (AA). Although catheter ablation of AA is effective in the general population, its efficacy and safety in patients with CA remain unclear.
Objective: The study aimed to evaluate outcomes in patients with CA undergoing catheter ablation for typical atrial flutter (TAFL) and left atrial (LA) arrhythmias and to assess the presence and influence of LA low-voltage areas (LVA) in the latter.
