Median time between the first and the second PFO closure procedure was 17 months (range 12–60 months). Deployment of a second device was successful in 92% (25/27) patients. A Type I defect was closed by using a coil or Amplatzer Vascular Plugs. In two patients a surgical option was chosen as a first option. A Type II defect was closed by using a double disc device. At a median follow‐up of 36 months (range 12–60 months), two subjects showed significant residual shunting between the two disks of the device (Type I) at 12 months follow‐up and were sent to surgery.</p> </sec> <sec id="ccd25097-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Significant residual shunts can be successfully closed by using a second device. Care is required to select an optimal device depending on anatomy and original device. In some subjects, lack of endothelial covering account for the persistence of a significant residual shunting. © 2013 Wiley Periodicals, Inc.</p> </sec> </abstract>
