From: Different Responses of Left Atrium and Left Atrial Appendage to Radiofrequency Catheter Ablation of Atrial Fibrillation: a Follow Up MRI study

Figure 2

The influence of RFCA on LA and LAA volume. (a) LA volume was significantly decreased after RFCA. (b,c) LAA volume and LAA to LA volume ratio were significantly increased after RFCA. (d) LA diameter measured by TTE was also significantly decreased after RFCA. LA: left atrium; LAA: left atrial appendage; RFCA: radiofrequency catheter ablation; TTE: transthoracic echocardiography.
