摘      要：Objective:Overriding/straddling of an atrioventricular valve is a consequence of atrial-ventricular septal *** sought to characterize the malalignment by analogizing it to a flap-door and using structured ***:The echocardiograms and magnetic resonance images of 35 patients with overriding/straddling tricuspid or mitral valve were evaluated to assess the following modifiers;the malaligned part of the septum,the reference structure,and the mechanism,direction and severity of ***:The pathology included classic overriding tricuspid valve in 15,classic overriding mitral valve in 12,and overriding tricuspid valve with left juxtaposition of atrial appendages in *** classic overriding tricuspid valve,the ventricular septum was hinged to the anterior interventricular groove and its insertion to the posterior interventricular groove was displaced toward the right *** VSD primarily involved the inlet but also extended toward the anterior interventricular *** classic overriding mitral valve,the ventricular septum was hinged to the posterior interventricular groove and crux *** insertion to the anterior interventricular groove was displaced toward the left *** VSD primarily involved the anterior part but also extended toward the *** tricuspid valve with left juxtaposition of atrial appendages had a mild degree of malalignment with displacement/rotation of the atrioventricular *** spaced short-axis images were most helpful in characterizing the ***:Overriding/straddling atrioventricular valves can be easily understood by analogizing the atrial-ventricular septal malalignment to a flap-door and describing the pathology in a structured *** to what has previously been known,the VSD is not limited to the inlet or outlet part of the ventricular septum.
