Primary End Points
All of the surgical LAA occlusion were performed successfully. The mean LAA width was 23.3 ±3.1mm (Table 2) and the mean LAA work length was 26.0±5.4mm. The mean diameter of the seal plate of the devices was 25.1±3.3mm. All of the devices were implanted successfully. Because the procedures were combined with bilateral pulmonary veins isolation, the plugging time alone could not be calculated accurately. But it could usually be done in 10 minutes.
