Impact of Pulsed-Field Ablation-Based Pulmonary Vein Isolation on Atrial Fibrillation Triggers Originating from the Superior Vena Cava.

Non-pulmonary vein (non-PV) atrial fibrillation (AF) triggers, including those originating from the superior vena cava (SVC), are an important source of AF initiation beyond the pulmonary veins.

Towards novel methods of dosimetry in pediatric and neonatal head computed tomography: Comparative study using two novel and cost effective fabricated in-house phantoms.

Accurate radiation dose assessment in pediatric computed tomography (CT) is essential due to children's higher radiosensitivity and anatomical differences from adults. Standard homogeneous adult phantoms often underestimate pediatric doses, especially in head imaging. This study performs a comparative dosimetry using two novel in-house developed heterogeneous head phantoms.

Right Atrial Functional Reserve is Associated With Right Ventricular Diastolic Reserve and Liver Stiffness in Repaired Tetralogy of Fallot.

The importance of right atrial (RA) functional reserve during exercise is recognized in patients with heart failure with preserved ejection fraction. This study aimed to determine RA functional reserve during exercise and to explore its associations with right ventricular (RV) functional reserve and liver stiffness in patients with repaired TOF.
