Figures:
Figure 1 : Apical 4-chamber view at 24 weeks of pregnancy
showing the accessory chamber (AC) and the main chamber (MC) of the left
ventricle separated by abnormal muscle bundle. LA: left atria, RA: right
atria; RV: right ventricle.
Figure 2: Apical view showing that the main chamber (MC) of the
left ventricle was in connection with mitral and aortic valves. AC:
Accessory chamber; Ao: ascending aorta; LA: left atria; RV: right
ventricle.
Figure 3: M-mode echocardiogram demonstrating that the
accessory chamber (AC) of the left ventricle contracted synchronously
with the main chamber (MC) and the right ventricle (RV).
Figure 4: M-mode color doppler showing bidirectional flow
across the communication between accessory chamber (AC) and main chamber
(MC) of the left ventricle. During diastole (D) red color indicates
filling of the AC. During systole (S), blue color indicates draining of
the AC towards the MC.
Figure 5: Postnatal subcostal view at 4 days of life confirming
prenatal finding. AC: accessory chamber, LA: left atria; MC: main
chamber; RA: right atria.
Figure 6 : Postnatal long axis parasternal view (A) at 4 days of
life and (B) at 8 weeks. At 8 weeks, the left ventricle (LV) is dilated
with interventricular septum bowing to the right. Ao: ascending aorta;
LA: left atria.
