Fluttering of the interventricular septum. The result of truncal insufficiency.
We present a child with truncus arteriosus and truncal insufficiency who had diastolic fluttering of the anterior mitral valve leaflet and left ventricular surface of the interventricular septum on echocardiogram. Although the fluttering has been previously described in patients with aortic insufficiency, it has not been reported with truncus arteriosus.
