Structural Abnormalities in Atrial Walls Are Associated With Presence and Persistency of Atrial Fibrillation But Not With Age

Objectives The purpose of this study was to assess the association between structural changes in human atria, age, and history of atrial fibrillation (AF). Background Development of fibrosis in atrial walls is associated with deterioration of atrial conduction and predisposes to AF in experiment. Hu... Full description

description: Objectives The purpose of this study was to assess the association between structural changes in human atria, age, and history of atrial fibrillation (AF). Background Development of fibrosis in atrial walls is associated with deterioration of atrial conduction and predisposes to AF in experiment. Human data, however, are scarce, and whether fibrosis is a cause or consequence of AF is not known. Methods Medical records for consecutive autopsies were checked for AF history and duration. Atrial specimens from 30 patients (ages 64 ± 12 years) were collected in 3 equal age-matched groups as patients without AF history, with paroxysmal AF, or with permanent AF. Tissue samples were obtained at the level of superior pulmonary veins, inferior pulmonary veins, center of posterior left atrial wall, terminal crest, and Bachmann's bundle. Histology sections were assessed for extent of fibrosis, fatty tissues, and inflammatory infiltration at each location. Results No correlation was observed between...
