We read the article ‘‘Successful percutaneous closure of a residual atrial septal defect due to device failure’’ written by S. Aguiar Rosa et al. with great interest. We congratulate the authors for nice three-dimensional echocardiographic images and successful management of the device failure. We also used the CARDIA Ultrasept ASD device in 9 patients in our center and three of them became defective after 19 to 25 months, causing significant shunts through the device frame and requiring repeat procedures. We recently reported a patient with a massive shunt due to spontaneous perforation of an Ultrasept Occluder polyvinyl alcohol (PVA) membrane. Based on our experience and the many cases reported with different versions of the Ultrasept prostheses, and considering the possibility of unnoticed and unreported failures, we would like to point out that we do not completely agree with the statement, ‘‘Although the use of this material (PVA membrane) in ASD closure devices is generally successful. . .’’, in the discussion section. The treatment options are surgical removal of the failing device and repair with a patch and covering of the damaged membrane with a second device. The authors chose the second option and occluded the defect successfully with a 20-mm Ultrasept PFO device. We would also like to mention a few issues about the ‘‘device-in-device technique’’ preferred by the authors. Nobody, either previous authors, including ourselves, or the manufacturer,

Residual shunt due to spontaneous perforation of polyvinyl alcohol membrane of ASD Occluder; what about after diagnosis?
