Data are presented as mean ± standard deviation or as number (percentage) of patients. LA = left atrium. A-P = anterior-posterior. RV = right ventricle. PA = pulmonary artery PA. Qp:Qs = pulmonary ow : systemic ow.
Procedure failures and complications
Device embolization occurred in three patients (3.7%), within one week in one patient and the next day, after closure, in two patients. The rst patient had a central 11 mm defect which was closed by 10.5 mm Occlutech, Flex II device. The closure procedure went smooth. The patient presented to the emergen- cy department with chest pain one week after closure of the defect. The symptoms started on the previous day after jumping on the trampoline. Echocardiog- raphy revealed that the device embolized to the left ventricular out ow tract. In the second patient, there was central 12 mm defect with some aortic rim de - ciency (5 mm) and double septal contour. The defect was closed by 12 mm Amplatzer septal occluder. Next day, echocardiography before discharge revealed that the device embolized to the left atrium. Both patients were referred for surgical removal of the device and defect closure. In the third patient, there was an eight mm central defect and double septal contour. The de- fect was closed by 9 mm Amplatzer septal occluder. Next day, chest X-ray before discharge revealed that the device embolized to the descending aorta. It was retrieved through a percutaneous trans-arterial ap- proach and the defect closed successfully by using a bigger (12 mm) Amplatzer septal occluder.
