Ablation of Atrial Arrhythmias After the Atriopulmonary Fontan Procedure

Arrhythmias after the Fontan procedure.

OBJECTIVE To study the determinants and outcome of arrhythmias after the Fontan type operation. DESIGN Retrospective analysis of data in patients operated on between 1972 and 1986 (follow up 5-19 years (mean 12 years)). PATIENTS All 60 patients undergoing a Fontan type procedure at the National Heart Hospital, London, during the study period (mean age (SD) 12.3 (6.8) years). RESULTS Posto...

Ablation of arrhythmias in adult patients after Fontan operation.

Juxtaposition of the atrial appendages: A nidus for thrombus in atriopulmonary Fontan?

Juxtaposition of atrial appendages is a rare cardiac congenital anomaly, usually associated with other cardiac malformations. Until now, it has not been linked to any significant clinical implications. We report cardiovascular magnetic resonance (CMR) findings of two adult patients who underwent atriopulmonary Fontan operation in the setting of left juxtaposition of the atrial appendages. The p...

Left atrial strain predicts recurrence of atrial arrhythmias after catheter ablation of persistent atrial fibrillation

INTRODUCTION Success rates of catheter ablation (CA) of persistent atrial fibrillation (AF) are very variable. Identifying patients in whom sinus rhythm maintenance cannot be achieved after CA is a critical issue. METHODS 2D speckle-tracking echocardiography was performed before the first CA procedure in consecutive patients with persistent AF. Left atrial (LA) strain was correlated with recu...

Predictors of atrial rhythm after atrioventricular node ablation for the treatment of paroxysmal atrial arrhythmias.

OBJECTIVE To assess the natural history of the atrial rhythm of patients with paroxysmal atrial arrhythmias undergoing atrioventricular node ablation and permanent pacemaker implantation. DESIGN AND SETTING A retrospective cohort study of consecutive patients identified from the pacemaker database and electrophysiology records of a tertiary referral hospital. PATIENTS 62 consecutive patient...
