Abstract

We present a case of secondary atrial septal defect transcatheter correction attempt in a 72 years old male, complicated by the device migration. The occluder was captured, pulled down to the common femoral artery and retrieved through the arteriotomy site. Second attempt was successfully performed using combination of transesophageal echo (TEE) and sizing balloon to accurately measure the defect diameter. This case underscores the importance of TEE ultrasound, sizing balloon, and contrast fluoroscopy combination to achieve accurate device sizing. Our calculation approach significantly increased the success rate of the septal defect closure procedure and potentially reduced the risk of immediate and mid-term complications. Combination of measuring methods should be used in order to accurately assess the device diameter.
