Article Synopsis
- This study evaluates the results of concomitant cryo-ablation for treating atrial fibrillation (AF) in patients also undergoing cardiac surgery.
- Researchers analyzed data from 103 patients after they had a hybrid treatment involving radiofrequency catheter ablation performed 105 days post-surgery.
- The findings showed that a significant number of patients had successful isolation of pulmonary veins and conduction blocks, with specific areas exhibiting more gaps, indicating varied effectiveness in the ablation technique.
Aims: Data on the hybrid atrial fibrillation (AF) treatment are lacking in patients with structural heart disease undergoing concomitant CryoMaze procedures. The aim was to assess whether the timely pre-emptive catheter ablation would achieve higher freedom from AF or atrial tachycardia (AT) and be associated with better clinical outcomes than surgical ablation alone.
Methods And Results: The trial investigated patients with non-paroxysmal AF undergoing coronary artery bypass grafting and/or valve repair/replacement with mandatory concomitant CryoMaze procedure who were randomly assigned to undergo either radiofrequency catheter ablation [Hybrid Group (HG)] or no further treatment (Surgery Group).
Article Synopsis
- * The SurHyb study is a randomized trial comparing the effectiveness of surgical CryoMaze alone versus a combined approach of CryoMaze followed by radiofrequency catheter ablation after three months in patients with persistent atrial fibrillation.
- * This study aims to provide deeper insights into which treatment option is more effective for patients undergoing surgery, potentially improving outcomes for those with atrial fibrillation during heart surgeries.
Changes in cognitive function after thoracoscopic and catheter ablation for atrial fibrillation.
Pacing Clin Electrophysiol
January 2023
Background: Comparative data regarding the effect of percutaneous and thoracoscopic ablation of atrial fibrillation (AF) on cognitive function are very limited. The aim of the study was to determine and compare the effect of both types of ablations on patient cognitive functions in the mid-term.
Methods: Patients with AF indicated for ablation procedure were included.
The Efficacy and Safety of Hybrid Ablations for Atrial Fibrillation.
JACC Clin Electrophysiol
December 2021
Objectives: This study sought to comprehensively determine the procedural safety and midterm efficacy of hybrid ablations.
Background: Hybrid ablation of atrial fibrillation (AF) (thoracoscopic ablation followed by catheter ablation) has been used for patients with nonparoxysmal AF; however, accurate data regarding efficacy and safety are still limited.
Methods: Patients with nonparoxysmal AF underwent thoracoscopic, off-pump ablation using the COBRA Fusion radiofrequency system (Estech) followed by a catheter ablation 3 months afterward.
Background: Hybrid ablation (i.e., a combination of a thoracoscopic surgical ablation followed by a catheter ablation) is a treatment option for patients with non-paroxysmal atrial fibrillation (AF).
