Abstract:
Objective To establish the optimal section planes for observing ventricular septal defect(VSD) by real-time three dimensional echocardiography(RT-3DE).Methods In 6 pig hearts with different types of VSD, after high pressural perfusion with coupling reagent, two dimensional, dual plane and RT-3DE were performed with different section planes, estimating with half quantificational visional grade:4 marks,very clear;3 marks,clear;2 marks,not clear enough; 1 marks,not clear. Results Observation by RT-3DE, en-face view of atrial-ventricular(S2a) and en-face view of left ventricular septum(L1a) provided relatively ideal section planes in sub-arterial ventricular septal defect, S2a and en-face view of right ventricular septum(L2a) provided relatively ideal section planes in perimembranous and muscular VSD. Conclusions S2a reflects relatively ideal section plane in sub-arterial, perimembranous and muscular VSD.
