Array-based genome-wide transcriptome analysis of the left atrial appendage for the difference between SR maintenance group and AF recurrence group. Array-based genome-wide transcriptome analysis of the left atrial appendage for the difference between SR maintenance group and AF recurrence group

Atrial fibrillation (AF), which causes cardiogenic cerebral infarction, is the most common type of persistent arrhythmia, and its incidence increases with age. We performed a radial procedure using an RF ablation device to restore sinus rhythm (SR). Overall design: Microarray analysis of the difference between the SR maintenance group (n=4) and the AF recurrence group (n=3) after Maze surgery was performed using FFPE samples of left atrial appendage.
