[Late complications of percutaneous closure of atrial septal defects with the Sideris occluder].
Between June 1992 and January 1996, 27 patients aged 3.9 to 74 years with an ostium secundum (22 patients) or patent foramen ovale with right-to-left shunts (5 patients) underwent percutaneous closure of their atrial septal defects with the Sideris occluder. After a thromboembolic complication, transesophageal echocardiography was performed routinely after the procedure in 15 patients between 1 month and 2 years, and in 6 patients on the 15th day. Two patients died, on the 2nd day and 21st month, of non-related causes. After an average follow-up of 33 months, 59% of patients had complete occlusion of the atrial septal defects or only a minimal residual shunt. Displacement of the prosthesis was defects or only a minimal residual shunt. Displacement of the prosthesis was observed in 7 cases with no relationship to size: 4 parallel to the septum with reappearance or increase in shunt, 3 with tilting of the prosthesis. All of these patients had a large residual defect compared with 20% with a normally positioned prosthesis (p < 0.05). Tilting of the occluder was associated with left atrial thrombosis (present in 40% of these patients), complicated by systemic embolism in one case: there were no cases of left atrial thrombus in the 9 with complete occlusion and the 5 patients with an isolated residual defect (p < 0.05). Occlusion of atrial septal defect with the Sideris device is effective and a safe method in the majority of cases. However, a badly positioned prosthesis with a residual shunt should be extracted as seen as possible or within three weeks if displacement is observed at control echocardiography.
