Background: Pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (PAF) can be performed using one-shot cryoballoon ablation (cryo) or point-by-point radiofrequency ablation (RF). This study compares the changes in P-wave parameters between both ablation methods.
Methods: This single-centre retrospective study included contact force RF and second-generation cryo for PAF between 2018 and 2019.

Background: Pulmonary vein isolation (PVI) is the most promising management method for paroxysmal atrial fibrillation (PAF). The P wave in the electrocardiogram (ECG) represents atrial depolarization. This study aims to correlate P-wave parameters after PVI with outcomes.

- This study investigates the impact of two types of ablation (radiofrequency and cryoballoon) on the quality of life (QoL) in patients with paroxysmal atrial fibrillation (PAF).
- Both RF and cryo procedures showed significant improvements in QoL metrics after 12 months, with sustained benefits at 30 months, indicating both methods are effective.
- However, performing additional ablations did not result in further QoL enhancements compared to those who only underwent pulmonary vein isolation (PVI).

Background: Pulmonary vein isolation (PVI) has been established as an effective management option for symptomatic paroxysmal atrial fibrillation (PAF). We aimed to explore the role of P-wave parameters in a 12-lead electrocardiogram (ECG) in predicting the success of repeat PAF ablation.
Methods: We enrolled consecutive patients who underwent a second AF ablation procedure for PAF in a UK tertiary center after an index ablation conducted between 2018 and 2019 and a repeat ablation up to 2021.
Simulation program staff and leadership often struggle to partner with front-line healthcare workers, their managers, and health system leaders. Simulation-based learning programs are too often seen as burdensome add-ons rather than essential mechanisms supporting clinical workforce readiness. Healthcare system leaders grappling with declining morale, economic pressure, and too few qualified staff often don't see how simulation can help them, and we simulation program leaders can't seem to bridge this gap.
