Atrioventricular Septal Defects -Pathologic Observations and Double Contrast Specimen Radiography-

Abstract

With five specimens of AVSD's from autopsy file of the Seoul National University Hospital, the following items were analysed; 1. external appearance of the heart, 2. atrial and ventricular aspects of the septal defects, 3. inlet septum of the left ventricle, 4. left ventricular outflow tract, 5. aortic valve, 6. atrioventricular valve annulus. After complete analysis, double contrast specimen radiography was performed. Common pathologic features of the AVSD's were globar external appearance, large septal defect at the atrioventricular junction, short posterior inlet septum or diaphragmatic wall of the left ventricle, elongation and narrowing of the left ventricular outflow tract, anterior and rightward displacement of the aortic valve and malorientation of the atrioventricular valve annulus.
