Open AccessThe role of the pulmonary veins on left atrial flow patterns and thrombus formation
Atrial fibrillation (AF) is the most common human arrhythmia, forming thrombi mostly in the left atrial appendage (LAA). However, the relation between LAA morphology, blood patterns and clot formation is not y...

Patient Stratification Based on Fast Simulation of Cardiac Electrophysiology on Digital Twins
After a myocardial infarction, electrophysiologists must assess the risk of the patient to develop a lethal arrhythmia. A cardiac magnetic resonance can help to evaluate the infarcted region, and provide insig...

Preventive substrate ablation in chronic post-myocardial infarction patients with high-risk scar characteristics for ventricular arrhythmias: rationale and design of PREVENT-VT study
Recent studies showed that an early strategy for ventricular tachycardia (VT) ablation resulted in reduction of VT episodes or mortality. Cardiac magnetic resonance (CMR)-derived border zone channel (BZC) mass...

Relationship between the posterior atrial wall and the esophagus: esophageal position and temperature measurement during atrial fibrillation ablation (AWESOME-AF). A randomized controlled trial
Pulmonary vein isolation (PVI) implies unavoidable ablation lesions to the left atrial posterior wall, which is closely related to the esophagus, leading to several potential complications. This study evaluate...
