[Surgical treatment for atrial fibrillation using ablation devices and ablation of autonomic ganglion plexi].

Background: Development of ablation device for the surgical treatment for atrial fibrillation (Af) has suggested the safety and easiness of the maze procedure. However, the success rate of sinus rhythm (SR) recovery is not satisfactory. We studied the maze procedure and the results with ablation device and also with additional ganglion plexi (GP) ablation.

Indication of posterior restoration and surgical results in patients with dilated cardiomyopathy.

Objective: Nontransplant surgery for dilated cardiomyopathy (DCM) has been in the process of development. Anterior restoration for anterior akinesis has shown favourable outcome. Posterior restoration and surgical results are also discussed.
