Incidence and Characteristics of Left Atrial Appendage Stumps After Device-Enabled Epicardial Closure

The authors analyzed the effectiveness of left atrial appendage closure with AtriClip in 43 patients. In all patients, the absence of blood flow in the excluded appendage was confirmed. In 31 patients, no residual stump was observed. In only one patient, there was a significant (>10 mm) stump. In 11 patients, the residual stump was less than 10 mm. The authors concluded that the left atrial appendage closure with AtriClip is effective and the definition of clinical significant left atrial appendage stump should be further evaluated.
