Background: The epicardial connections (ECs) via intercaval fibres connecting the right-sided pulmonary veins (PVs) and right atrium (RA) can preclude isolation of the right-sided PVs. Such ECs occasionally have a unidirectional conduction property.
Case Summary: A 62-year-old man was referred to our institution for catheter ablation of paroxysmal atrial fibrillation (PAF).
High-density electroanatomic mapping of atriofascicular pathways using multipolar mapping catheters can identify oblique pathways and avoid mechanical bump termination.

Background: Atriofascicular fibers (AFFs) are rare accessory pathways that have higher rates of recurrence after ablation because of either failure to identify AFF (M) potentials or mechanical termination with contact.
Objective: We aimed to evaluate whether electroanatomic mapping (EAM) using multielectrode, high-density nonlinear catheters can reliably localize AFF potentials and determine a site for ablation without causing mechanical termination.
Methods: Seven patients underwent electrophysiology studies (EPS) and EAM using high-density, multielectrode catheters for antidromic tachycardia using AFFs.

Article Synopsis
- This study investigates how the electrophysiological properties of ventricular pre-excitation change in young athletes over time, particularly when assessing their eligibility for sports participation.
- A total of 44 pediatric patients were monitored over a minimum of two years, showing significant changes in parameters such as the accessory pathway's effective refractory period during stress tests, suggesting a need for regular follow-ups.
- The findings indicate that some patients shifted their risk profiles for cardiac issues, emphasizing the necessity of repeat electrophysiological evaluations to ensure accurate risk assessments for athletic activities.

Introduction The human lungs are located in the pleural cavity, divided by fissures into lobes, facilitating respiration movements. It acts as a barrier to prevent the spread of infection to adjacent lobes. The pulmonary hilum in each lung contains pulmonary vessels, bronchial vessels, and the bronchus.
