Fig. 1. ( A) Two-dimensional image of fetal echocardiography showing the 5-chamber view. A perimembranous VSD and aAo overring inter-ventricular septum was seen. (B) Two-dimensional and color doppler image of fetal echocardiography showing three vessels view. Stenotic PA was seen on normal position, but pulmonary valve and pulmonary forward blood flow from the right ventricle was not detected. (C) Two-dimensional and color doppler image of fetal echocardiography showing RV outflow view. aAo originated from both RV and LV, but the PA trunk was not detected. MAPCA originating from dAo connected PA without DA.
VSD, ventricular septum defect; aAo, ascending aorta; PA, pulmonary artery; RV, right ventricle; LV, left ventricle; MAPCA, major aortopulmonary collateral artery; DA, ductus arteriosus; dAo, descending aorta.
Fig. 2. (A) Two-dimensional image of fetal echocardiography showing three vessels, tracheal view. Coronary pulmonary artery fistula (CPAF) seems to originate from aAo and communicate with mPA. (B) Color Doppler image of fetal echocardiography showing CPAF supplied blood flow toward mPA. (C) Schema of the fetal echocardiography is shown in Figure 2A and 2B.
CPAF, coronary pulmonary artery fistula; aAo, ascending aorta; mPA, main pulmonary artery
Fig. 3. (A) Aortography shows CPAF originates from RCA and subsequently is connected to the MPA. (B) Electrocardiogram (ECG)-gated 320-row computed tomography angiography (CTA) shows the right coronary artery (RCA) and left coronary artery (LCA) originating from the normal coronary sinus. (C) ECG-gated 320-row CTAespecially shows the positional relationship of RCA and CPAF. RCA and LCA originate from the normal coronary sinus. CPAF originates from the RCA and subsequently is connected to the mPA. The central PA and two MAPCAs supply blood to the same lung field.
RCA, right coronary artery; RVB, right ventricular branch; LCA, left coronary artery; aAo, ascending aorta; dAo, descending aorta; CPAF, coronary pulmonary artery fistula; MAPCA, major aortopulmonary collateral artery; MPA, main pulmonary artery, RPA, right pulmonary artery; LPA, left pulmonary artery.
