The use of transesophageal echocardiography monitoring of transcatheter closure of a persistent ductus arteriosus.

ABSTRACT

We performed transesophageal echocardiography (TEE) with pediatric biplane probes throughout the procedure of transcatheter closure of the ductus arteriosus in 42 out of 46 patients who were scheduled for this intervention. Patient ages ranged from 15 months to 14 years and body weight from 9-53 kg. Both Rashkind double umbrella devices and coils were used. The described approach resulted in fewer contrast injections and was helpful in monitoring the procedure and in deciding when to release the device. To the best of our knowledge this is the first report describing a large series where continuous monitoring of transcatheter ductus closure was combined with x-ray fluoroscopy and TEE.
