A 44-year-old woman with a history of transient ischemic attack underwent closure of atrial septal defect with a 26 mm Amplatzer device. The device was released without residual shunt or impingement on intracardiac structures. Within seconds, the transesophageal echocardiography showed the initial dislodgement of the device from the atrial septum and its consequent slipping back into the right atrium close to the tricuspid valve. Soon after the device disappeared from the right atrium and it could be founded into the right ventricle under the tricuspid valve. The patient was transferred in the operating room for an emergency operation. The device could not be found in the right ventricle because its downstream migration. The Amplatzer septal occluder was identified by palpation into the pulmonary artery trunk: it was retrieved from the right ventricle through the pulmonary valve and the atrial septal defect was closed by running suture.

Time between TEE and surgery seems to be an important factor affecting comparison. Lesion characteristics appear to be more precise and concordant with surgical findings the shorter the time elapsed from TEE to surgery. Changes resulting from disease progression require repeat TEE evaluation prior to surgical intervention for IE-related complications. This could be useful in providing the surgeon with a more accurate definition of valvular lesions for optimal planning of intervention.
