Interest of waiting time for spontaneous early reconnection after cavotricuspid isthmus ablation: A monocentric randomized trial.

Introduction: The aim of this study was to determine the rate of recurrent atrial flutter (AFl) after isolated cavotricuspid isthmus (CTI) ablation and to evaluate the impact of a waiting period with the search for early resumption of the CTI block on the long-term outcome.

Method: Three hundred and nineteen consecutive patients referred for typical AFl ablation were randomly assigned to CTI ablation with continuous reevaluation of the CTI block during 30 minutes and early reablation if needed (waiting time [WT] + group, n  =  155) or to CTI ablation with no waiting period after proven bidirectional CTI block (WT - group, n  =  164). All patients were regularly followed-up.

Low contact force and force-time integral predict early recovery and dormant conduction revealed by adenosine after pulmonary vein isolation.

Aim: After pulmonary vein isolation (PVI), dormant conduction (DC) is present in at least one vein in a substantial number of patients. The present study seeks to determine whether there is a relationship between poor contact forces (CF) and the presence of DC after PVI.

Methods And Results: This prospective, operator-blinded, non-randomized dual-centre trial enrolled 34 consecutive patients with paroxysmal atrial fibrillation who were candidates for PVI.

Left atrial appendage occlusion and pulmonary vein isolation: interest of non-invasive imaging.

A 67-year-old woman with paroxysmal atrial fibrillation (AF), not a candidate for anticoagulant therapy, underwent a combined procedure of pulmonary vein isolation (PVI) and occlusion of the left atrial appendage (LAA) with the Amplatzer cardiac plug prosthesis (AGA Medical Corporation, Plymouth, U.S.A.
