Atrial fibrillation (AF) is the most frequent arrhythmia, and is responsible for significant morbidity and mortality. Its interventional treatment requires electrical isolation of the pulmonary veins, and usually additional ablation of specific atrial zones is performed in the setting of persistent AF. Persistent AF ablation based on...

A recent patient-tailored ablation protocol to treat atrial fibrillation consists in identifying ablation sites based on their spatiotemporal dispersion (STD). STD represents a delay of the cardiac activation observed in intracardiac electrograms (EGMs) across contiguous leads. This work aims at automatically identifying ablation sites by...

Atrial fibrillation (AF) is a sustained arrhythmia whose mechanisms are still largely unknown. A recent patient-tailored AF ablation therapy is based on the use of a multipolar mapping catheter called PentaRay. This new protocol targets areas of spatiotemporal dispersion (STD) in the atria as potentialAF drivers. However, interventional...

Atrial Fibrillation (AF) is the most widespread sustained arrhythmia in clinical practice. A recent personalized AF therapy consists in ablating areas displaying spatiotemporal dispersion (STD) electrograms (EGM) with the use of catheters. Interventional cardiologists use a multipolar mapping catheter called PentaRay to identify visually atrial...

Atrial fibrillation (AF) is a common cardiac condition that predominantly affects the elderly, posing a significant risk for stroke and raising public health concerns. Catheter ablation (CA) is the most effective long-term treatment for persistent AF. A novel CA approach based on spatio-temporal dispersion (STD) targets active zones that...

Atrial fibrillation (AF) is a common heart condition in the elderly, significantly increasing stroke risk and posing a public health concern. Among treatments, catheter ablation (CA) is the most effective long-term solution for persistent AF. A new CA technique targets spatio-temporal dispersion (STD) patterns in intracardiac electrograms...
