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.
