Transcatheter closure of patent ductus arteriosus

Case contributed by Dr Vincent Tatco


Known case of patent ductus arteriosus (PDA) confirmed by echocardiography.

Patient Data

Age: 35
Gender: Female
Modality: X-ray

Pulmonary vascularity is increased.

Heart is enlarged with dilated left ventricle.

The aorta and main pulmonary artery segment are dilated.  Calcifications are seen at the aortopulmonary window.

Modality: DSA (angiography)

A 5Fr Judkins Right 4 (JR4) catheter was used for right heart cardiac catheterization while a 5Fr pigtail catheter was placed in the descending aorta. Descending aortogram in the lateral and RAO views were done to visualize the PDA. A duct occluder was implanted. Repeat descending aortogram after deployment showed complete occlusion of the PDA.

Modality: X-ray

The PDA closure device (duct occluder) is seen in place.


Case Discussion

This case demonstrates the classic radiographic appearance of patent ductus arteriosus (PDA) and a technique used to close the shunt with a duct occluder. The duct occluder is one of the numerous medical devices that can be seen on chest radiographs.
