Echocardiographic findings before and after interventional occlusion of a persistent ductus arteriosus Botalli using the Rashkind Occluder System

AIM: The aim of this study was to investigate whether before releasing the Rashkind occluder system for occlusion of persistently patent ductus arteriosi Botalli from the delivery catheter its position can be adequately demonstrated sonographically to avoid angiography. METHOD: From March to August 1993 occlusion of a persistently patent ductus arteriosus by means of the Rashkind system was carried out in 10 patients. A standard technique using transthoracic echocardiography was used. RESULTS: Echocardiography allowed to demonstrate and locate the occluder system in all cases. CONCLUSION: Echocardiography is a reliable means for locating the Rashkind occluder system avoiding angiography.
