Effect of radiofrequency catheter ablation of persistent atrial fibrillation on the left atrial function: Assessment by 320-row multislice computed tomography

2017 HRS/EHRA/ECAS/APHRS/SOLAECE expert consensus statement on catheter and surgical ablation of atrial fibrillation

“… 1106 However, because AF eliminates essentially all contractility of the LA, there is general agreement that restoration of sinus rhythm in patients with persistent AF improves atrial function if sinus rhythm is maintained. 391 , 1107 , 1108 , 1109 …”

Restoration of Mitral Inflow Velocity Until Blanking Period Is Associated With Successful Ablation for Persistent Atrial Fibrillation

“…However, the reliability of LA contractility or compliance measures depends on the imaging tools used and the study groups involved. 5,6,9,13,14) We demonstrated that LA size is reduced following RFCA, and that LA size is associated with the success of catheter ablation. In addition to LA size reduction, the restoration of peak A wave velocity, which signals the recovery of atrial contractility, was observed without 3D echocardiography, CT, or MRI.…”

Improvement in quality of life and cardiac function after catheter ablation for asymptomatic persistent atrial fibrillation

“…The reduction in the end‐systolic volume because of LVEF improvement suggested an acute effect of SR restoration and the possibility of left ventricular reverse remodeling 28 . In addition, the decrease in LAD in TTE and the reduction in the CT LA volume after CA represent LA reverse remodeling 12 . These series of improvements in cardiac function may predict a reduction in long‐term mortality and heart failure events 29‐31 …”

“…The plasma B‐type natriuretic peptide (BNP) level, which reflects left ventricular end‐diastolic pressure and is known as a marker of heart failure, was examined 10,11 . In addition, left atrial (LA) volume was measured by contrast‐enhanced cardiac computed tomography (CT) scan as an indicator of LA remodeling 12 . Moreover, left ventricular ejection fraction (LVEF) and LA diameter (LAD), which are indicators of the left ventricular systolic and diastolic function, respectively, were measured with transthoracic echocardiography (TTE) 13 .…”
