Impact of left atrial volume, sphericity, and fibrosis on the outcome of catheter ablation for atrial fibrillation

Introduction To investigate the relation between left atrial (LA) volume, sphericity, and fibrotic content derived from contrast‐enhanced cardiac magnetic resonance imaging (CE‐CMR) and their impact on the outcome of catheter ablation for atrial fibrillation (AF). Methods and results In 83 patients...

Zusammenfassung:Introduction To investigate the relation between left atrial (LA) volume, sphericity, and fibrotic content derived from contrast‐enhanced cardiac magnetic resonance imaging (CE‐CMR) and their impact on the outcome of catheter ablation for atrial fibrillation (AF). Methods and results In 83 patients undergoing catheter ablation for AF, CE‐CMR was used to assess LA volume, sphericity, and fibrosis. There was a significant correlation between LA volume and sphericity (R  =  0.535, P
