MORPHOLOGICAL DIAGNOSIS OF ATRIOVENTRICULAR SEPTAL DEFECT: COMPARISON BETWEEN TWO DIMENSIONAL ECHOCARDIOGRAPHY, ANGIOCARDIOGRAPHY AND SURGERY

The selection and result of operative procedure for repairing atrioventricular septal defect (AVSD) are largely dependent on completeness and accuracy of preoperative morphological diagnosis. To evaluate the value of two dimensional echocardiographic (2DE) technique devised specifically for morpholagical diagnosis, the results of 2DE,angiocardiography and surgery were examined retrospectively in 87 children with AVSD.Age ranged from 3 months to 11 years old (mean 3.9 years). 46 had partial AVSD, 12 had transitional AVSD, 29 had complete AVSD (type A in 21, type B in 4, type C in 4).2DE diagnosis is concordant with surgical diagnosis in 36/37 (97%) patients with partial AVSD, in 25/31 (84%) patients with transitional or complete AVSD. Most discordant diagnosis between 2DE and surgery occurred in patients with transitional or type A AVSD.The 2DE technique for morphological diagnosis of A VSD is superior to angiocardiography.The results indicated that morphological manifestations of AVSD could be clearly demonstrated with the use of apical and subxiphoid 2D imaging planes, reliable morphological diagnosis could be obtained.
