OBJECTIVES We report an in-depth postmortem morphologic analysis of atrial myocardium in human pulmonary veins (PVs) from patients with and without atrial fibrillation (AF). BACKGROUND Electrophysiologic studies established the critical role of PVs in the initiation of AF. To date, a paucity of data exists about PV morphology as an arrhythmogenic substrate. METHODS Longitudinal tissue-strips of PVs were excised and histologically analyzed from the distal part to just beyond the atriovenous… CONTINUE READING
