AF is the most common sustained cardiac arrhythmia seen in clinical practice and is associated with significant morbidity and mortality. Other atrial arrhythmias originating from the PVs include premature atrial contractions and ectopic atrial tachycardia. Because it is established that the PVs play a crucial role in the genesis and maintenance of AF, the electrical isolation of PVs has become the cornerstone for the treatment of this arrhythmia.
