Incessant atrial flutter after device closure of atrial septal defect: successful radio frequency ablation.
A four-month-old baby presented with failure to thrive and congestive cardiac failure precipitated by a lower respiratory tract infection. He was found to have a large ostium secundum atrial septal defect measuring 18 mm. This was successfully closed percutaneously by a device (Blockaid). A month after the device deployment the child developed typical atrial flutter. Despite rate control drugs the ventricular rate remained 140/min over the next several months. In view of the incessant atrial flutter with fast ventricular response, the child underwent radiofrequency ablation at the age of 2 years. An isthmus block was created which successfully terminated the tachycardia.
