Results of Transcatheter Closure of Complex ASD's

Abstract

Background & Aim: Transcatheter closure of atrial septum defect (ASD) is widely used to close most secondary ASD's. In our study we aimed to determine the possibility and safety of closing complex ASD's through transdermal catheter by reviewing our experience in closing this kind of lesions.

Materials and Methods: Retrospective study of cases of transcatheter ASD closure we did between 2008-2017. Complex ASD is an ASD with deficient one or more of six rims, large, multiple defects or in case of existence of aneurism. We studied the rate of success of closing, complications, with following up patients clinically and by echocardiography.  

Results: Transcatheter ASD closure was don’t to 74 patients (19 male, mean age 23 years), with 98.6% primary success. Two cases of early embolization, one case of pericardial effusion due to erosion, and one case of massive bleeding from femoral entrance point were all the complications we met during the next 48 hours after intervention. All patients were followed up for 24 months clinically and by echocardiography, with no complication or residual shunt.

Conclusion:  Complex ASD can be closed by transcatheter techniques with high rates of early and late success, and low rates of complications.
