Abstract

We report embolization of a bioabsorbable immediate-release patch for closure of atrial septal defect into left atrium with forward movement into and out of the mitral valve during each cardiac cycle. The dislodged device was ultimately explanted by a surgical operation and the defect was closed. We discuss causes and recommend tips to prevent such a serious potential complication. We also suggest some modifications to the device for making it more safe and effective.
