“…Congenital APVS was first described by Chevers in 1847 . In most cases, it is associated with VSD, obstructive pulmonary valve annulus, and massive dilatation of the pulmonary arteries, a combination of lesions often called TOF with absent pulmonary valve . Although conventional grayscale echocardiography and color Doppler usually allow a conclusive diagnosis for this rare anomaly, the number, shape, and motion of the pulmonary valve might not be fully evaluated by an obstetric sonographer.…”

Previous reports have demonstrated that 3D images of fetal semilunar valves 4 and atrioventricular valves 5 could be obtained using STIC technique.…”

“…In addition, the morphologic characteristics of the pulmonary valve such as the number of leaflets and the opening shape were visualized, which is a benefit of our study. As variable degree of annular stenosis is always present in most cases with APVS, we measured the area of the valve annulus by 3D echocardiography for a further evaluation of the annular stenosis. We also measured the area of the cleft of the pulmonary valve during diastole, which was valuable for evaluating the insufficiency of the pulmonary valve.…”

Absent pulmonary valve syndrome (APVS) is a rare congenital cardiac anomaly characterized by hypoplastic or even absent pulmonary valve, to-and-fro flow across the pulmonary valve annulus, and dilatation of main pulmonary artery and branches. It is crucial to evaluate the degree of dilatation of pulmonary arteries and the presence of associated malformation and chromosomal anomalies affecting pregnancy decision. We described two- and three-dimensional (3D) echocardiographic findings of one fetus with APVS and indicated the beneficial contribution of 3D technology in understanding the anatomy.

“…It is classified on the basis of presence or absence of ventricular septal defect (VSD) and features of TOF into Fallot type and non-Fallot type of APVS. [ 5 6] The incidence of APVS is rare as it accounts for 3-6% of cases of TOF and 0.2-0.4% of live-born infants with CHD. [ 5 7 ]…”

Absent pulmonary valve syndrome (APVS) is a rare congenital cardiac malformation characterized by absent, dysplastic, or rudimentary pulmonary valve leaflets in association with other cardiac anomalies. It has an incidence of 3-6% in cases of tetralogy of Fallot (TOF) and 0.2-0.4% of live-born infants with congenital heart disease (CHD). Absent pulmonary valve leads to dilated main pulmonary artery; presenting as a pulsatile, paracardiac cystic lesion on antenatal ultrasound (USG). We report a case of this rare anomaly in association with ventricular septal defect (VSD), TOF, and left axis deviation of heart detected at 23 weeks of gestation.

“…Absent pulmonary valve syndrome (APVS) is a unique and rare cardiac defect that occurs in 1% of fetuses with congenital heart defects and 0.2% to 0.4% of live births. 1 It entails a rudimentary and dysplastic pulmonary valve with severe regurgitation, leading to a dilated main pulmonary artery. There are two phenotypes that are differentiated by the presence of a ventricular septal defect (VSD).…”
