Abstract

Objective Although a narrow left ventricular outflow tract (LVOT) in atrioventricular septal defect (AVSD) is related to its intrinsic morphology, the contribution from repair technique remains to be quantified. Methods 108 AVSD patients with common atrio-ventricular valve orifice were divided into 2 groups: two-patch (N=67) and modified 1-patch (N=41) repair. LVOT morphometric was analysed by quantifying the degree of disproportion between subaortic:aortic annular dimensions (disproportionate morphometrics ratio was defined as ≤ 0.9). Z-scores (median, interquartile range) were further analysed in a subset of 80 patients with immediate pre- and post-operative echocardiography. 44 subjects with VSD served as controls. Results Pre-repair, 13(12%) AVSD had disproportionate morphometrics (vs 6(14%) VSD p=0.79); but subaortic Z-score (-0.53, -1.07 - 0.06) was lower than VSD (0.07, -0.57 - 1.17; p
