Hybrid Convergent Procedure
A combined surgical and catheter-based approach for treating atrial fibrillation. Involves epicardial surgical ablation followed by endocardial catheter ablation.
Full Definition
The hybrid convergent procedure represents a collaborative approach between cardiac surgeons and electrophysiologists for treating persistent atrial fibrillation that combines the benefits of surgical epicardial ablation with catheter-based endocardial techniques. The procedure typically involves thoracoscopic surgical access to create epicardial ablation lesions on the posterior left atrium and pulmonary vein antrum, followed by percutaneous catheter ablation to complete lesion sets and address any remaining conduction gaps. This staged approach allows for more comprehensive substrate modification than either technique alone, particularly in patients with enlarged atria or extensive fibrotic tissue. The convergent approach aims to improve success rates while potentially reducing procedure times and complications compared to complex redo catheter ablations.
Usage
