(11) Secundum ASD is the most common type (50-70%), while primum ASD (12) is less common at 15-30% and is often associated with defect of the atrioventricular valve. (11) Sinus venosus and coronary sinus defects are rare (Figures 1 and 2).
Fetal echocardiography was performed initially at 27 weeks and 2 days gestation, showing each twin had a complete, balanced AVSD of Rastelli type A consisting of a moderate-sided inlet VSD, a small primum ASD, a probable small secundum ASD, and a single atrioventricular valve with trivial left-sided and mild central atrioventricular valve regurgitation and a small predominantly apical pericardial effusion (Figures 1 and 2(a)-2(d)).
