LA PULSE: Evaluating Left Atrial Function Pre- and Post-Atrial Fibrillation Ablation Using PULSEd Field Ablation.

: Atrial fibrillation (AF) is a common cardiac arrhythmia associated with left atrial dysfunction. The impact of pulmonary vein isolation (PVI) using pulsed field ablation (PFA) on left atrial function has not been previously quantified. This study aims to evaluate the effects of PVI using PFA on left atrial function in patients with AF.

Elimination of refractory ventricular tachycardia storm and fibrillation using stereotactic radiotherapy.

Ventricular tachycardia storm is a potentially lethal condition with limited treatment options. Failed ablation is associated with a fourfold mortality increase in this population. Stereotactic body radiotherapy was proposed in these cases.
