The right anterior oblique view may be helpful by separating the ductus arteriosus from the aorta. This study was undertaken to evaluate the incidence of end-on patent ductus arteriosus and the utility of the right anterior oblique view during device closure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Aortography was performed in lateral and right anterior oblique views before, during, and after successful device deployment in 117 consecutive patients.

An end-on ductus arteriosus was present in 24 (20.5%) patients (14 type B, 10 type A). The right anterior oblique view was useful during device closure in 15 (12.8%) cases (all end-on type). Among all cases of end-on patent ductus arteriosus, it was useful in 62.5% (most type B and a few type A). In all of these, the device appeared obliquely oriented and foreshortened in the lateral view but fully profiled in the right anterior oblique view.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Recognizing an end-on patent ductus arteriosus and utilizing the right anterior oblique view simplified device closure.
