Is a common left pulmonary vein associated with arrhythmogenic atrial ectopy in patients with paroxysmal atrial fibrillation?
A common left pulmonary vein is a consistent anatomical source of arrhythmogenic atrial ectopy in patients with paroxysmal atrial fibrillation, and its targeted isolation can be curative.
Schwartzman et al. (2004) conducted an observational in paroxysmal atrial fibrillation (n=100). Computed tomographic scanning and invasive electrophysiology study was evaluated on Presence of common left pulmonary vein and its association with arrhythmogenic ectopy. A common left pulmonary vein was identified in 14% of subjects with paroxysmal atrial fibrillation and served as a consistent source of arrhythmogenic atrial ectopy.
