Mind the gap: quantification of incomplete ablation patterns after pulmonary vein isolation using minimum path search

Around 33.5 million people suffer from atrial fibrillation (AF) worldwide (Chugh et  al., 2014), the most frequent class of arrhythmia. The origin of AF is the appearance of rapid abnormal electrical signals activating the atrium in a disorganized way. Most of these abnormal electrical currents originate inside the pulmonary veins (Haissaguerre et al., 1998). Pulmonary vein isola tion (PVI), which aims to electrically isolate the PVs from the main atrial body, is a common treatment, especially for patients not responding to medication.
