“…7 Areas under the curve for atrial echo parameters are lower than were previously reported, 4 but differences in study cohorts (stable hypertensive outpatients versus hospitalized stroke patients), unblinded 4 compared with blinded assessment in our study as well as matching controls for age and sex, may explain these differences.…”

“…19, 20 In a small population study, Rodrigues et al noted an early reduction in atrial function within the first 12 h after ablation, with a subsequent improvement at 6 months. 19 The close monitoring of atrial function in the present study showed an unstable trend of atrial function during the follow-up period. It is well known that changes in LA function after RFCA depend on the balance between the beneficial effect of atrial remodeling and the harmful effect of edema and fibrosis.…”

Methods Patient EnrollmentFrom March to December 2013, all consecutive patients who underwent catheter ablation for paroxysmal or persistent AF in the electrophysiology laboratory were considered for enrollment. Only those who presented in sinus rhythm at baseline adiofrequency catheter ablation (RFCA) is an effective treatment in rhythm-control therapy for atrial fibrillation (AF), with a reduction in AF recurrence ranging from 50 to 80%. 1-3 By promoting a reduction in arrhythmic burden, RFCA improves symptoms and quality of life. 4,5Despite both structural and functional changes after RFCA having been extensively studied, the effect of AF ablation on left atrial (LA) function has not yet been sufficiently determined and remains a pivotal topic also with regard to the consequences of decision on whether to discontinue anticoagulation after successful ablation. 6 In patients with impaired LA function, the risk of thrombus formation is potentially augmented, irrespective of the classical risk factors. 7Pre-ablation LA function has been identified as an indepen- Background: Data are lacking on the effect of radiofrequency catheter ablation (RFCA) on atrial function. The aim of this study was to determine a cut-off of pre-ablation left atrial (LA) function in order to predict atrial functional recovery after RFCA. R
