Significant residual shunts may occur after surgical ligation of left atrial appendage and may be associated with increased cerebral and systemic embolization risk. Transcatheter left atrial appendage residual shunt occlusion procedure may be a safe and effective therapeutic alternative and the choice of the more appropriate device should be made on a case-by-case basis. The objective of this study was to report on a case of transcatheter closure of residual shunt after surgical left atrial appendage ligation with an off-label device.
