Hybrid Procedure in Patients With Persistent Atrial Fibrillation

Overview

In this study, the investigators therefore comparatively analyzed the mid-term results (at 1 year) including electrocardiogram, 24 hour Holter monitoring, and 2 week long-term electrocardiogram of thoracoscopic ablation and RFCA performed individually or as a hybrid procedure in patients with long-lasting persistent atrial fibrillation. Antiarrhythmic medication, discontinuation of anticoagulation medication, and echocardiographic findings were also analyzed.

Atrial fibrillation is highly associated with sudden death and stroke, requiring definitive treatment. In Korea, atrial fibrillation is a common disease predicted to affect more than 5% of the population over 65 years of age and more than 10% over 80 years. Totally thoracoscopic ablation has been adopted and performed successfully on February 2012 at Samsung Medical Center for the first time in Korea. More than 120 operations have been performed up to date. In Korea, treatment for atrial fibrillation is still dependent on percutaneous RFCA, and life-long medication and anticoagulation is needed when recurrent atrial fibrillation occurs. The investigators expected thoracoscopic ablation to be an alternative to overcome this limitation. Also, thoracoscopic ablation and RFCA are recently being performed simultaneously or stage by stage as a hybrid procedure, and the results are being reported. In this study, the investigators therefore comparatively analyzed the mid-term results (at 1 year) including electrocardiogram and 24 hour Holter monitoring of thoracoscopic ablation and RFCA performed individually or as a hybrid procedure in patients with long-lasting persistent atrial fibrillation. Antiarrhythmic medication, discontinuation of anticoagulation medication, and echocardiographic findings were also analyzed.
