Hybrid ablation

Combination of electrophysiological examination and catheter treatment as well as surgical ablation - the principle of the "best of two worlds". The hybrid procedure is especially suitable for patients with long-standing atrial fibrillation.

Combining expertise: The best of two worlds

The minimally invasive hybrid ablation procedure combines the expertise and technologies of electrophysiology and cardiac surgery. Hybrid ablation is made of two treatment strategies: Electrophysiological examination and treatment with the catheter from the inside, and surgical ablation and left atrial appendage closure from the outside. Recent studies show that the combination of both methods significantly improves outcomes in complex, persistent atrial fibrillation cases. The procedure is offered in a single session in the hybrid operating room or in two sessions with an interval offered by two different specialists.

Electrophysiology and heart surgery  

At the Heart & Rhythm center, we do a "teamwork" between the electrophysiologist and the heart surgeon which enables this range of therapies. We recommend the combination of 3D mapping techniques (display of the ECG in three dimensions by measurements in the heart), epicardial ablation (on the heart surface) and left atrial appendage closure as the best therapy for patients with complex atrial fibrillation. Before the intervention, the therapy combination between the electrophysiologist and the cardiac surgeon is discussed in detail and implemented as a HeartTeam decision in accordance with the latest guidelines. This is unique in Switzerland. 

Target population or hybrid approach

The hybrid procedure is particularly indicated in patients with long-standing atrial fibrillation, enlarged left atria, long standing hypertension or in those who the catheter therapy was unsuccessful. Especially complex situations like atypical atrial flutter can be treated with a hybrid procedure. 

Advantages and results of hybrid treatment

Our experience shows, that one year after treatment, most patients remain in normal sinus rhythm even without medications. 

There are several ways to do a hybrid procedure. We make a so-called "staged hybrid". First, surgical ablation is performed, which consists of epicardial ablations. These ablations target the pulmonary veins, the interatrial septum and many other places where extra pulmonary triggers can be identified. But most importantly the left atrial appendage is excluded and electrically isolated. In a second procedure, catheter ablation is performed, if necessary, to close any gaps after surgery. Hybrid ablations in persistent atrial fibrillation provide a success rate of over 80% with a very significant increase in quality of life (QOL).
