Intracardiac Echocardiography as a Guide for Transcatheter Closure of Patent Ductus Arteriosus

Figure 3

Representative case where ICE is a valuable guide for TC-PDA. Patient 23 has a large Krichenko type B PDA that was not delineated by an aortography (a) but was clearly visualized by ICE (closed circle) with a 11.1 mm PA side diameter and a 3.9 mm length (b). We chose Amplatzer septal occluder 17 mm for the closure of this PDA. During TC-PDA, ICE showed all process of procedure. We advanced a long sheath (arrowhead) through the PDA (c), opened the aortic skirt in the aorta (d), and pulled the entire system back and deployed right atrial disc (e). Finally, ICE showed small residual shunt just beside the body of device (f) and we finished the procedure successfully. Ao, aorta; ICE, intracardiac echocardiography; PA, pulmonary artery; PDA, patent ductus arteriosus; TC- PDA, transcatheter closure of patent ductus arteriosus.
