Brief Summary

Pulmonary atresia (PA)/critical stenosis (CS) with intact ventricular septum (PA/CS-IVS) is a rare congenital heart disease (CHD), that presents heterogeneously. Prognosis is conditioned by the possibility of achieving a primary repair with biventricular circulation (BV) or a one-and-a-half ventricle solution vs. a palliative approach bound to a univentricular (UV) circulation in which both survival and quality of life are significantly impaired. Predicting UV circulation prenatally is still a challenge. The aim of this study is: 1/ to evaluate the natural history of the disease and develop a prognostic model for the prediction of transplantation-free survival with a biventricular or a one-and-a-half repair at 2 years postnatal age 2/ To develop a model to predict the risk of right ventricle dependent coronary circulation 3/ To evaluate prenatal and postnatal outcomes in non-intervened fetuses with a confirmed postnatal diagnosis of PA-CS/IVS including Intrauterine death, neonatal/Infant death, number of required postnatal procedures, need for oxygen support, need for cardiac transplantation

Study Arms (2)

Retrospective cohort

Retrospective cases that meet all the inclusion criteria and none of the exclusion criteria from 2013 until 2023 will be included for model development. They should be non-intervened cases in order to assess the natural history of the disease.

Other: No intervention

Prospective cohort

Prospectively recruited cases will be included when meeting all the inclusion criteria and none of the exclusion ones. This cohort will serve as a validation cohort for the previously developed model. The nature of the study is observational. Clinicians will not be given the result of the model during the study and clinical practice will be routine.

Other: No intervention

Eligibility Criteria

Age16 Weeks - 28 Weeks
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)
Sampling MethodNon-Probability Sample
Study Population

Screening data: All pregnant women with a fetus with suspected PA-CS/IVS will be screened for eligibility. If they meet all the inclusion criteria and none of the exclusion ones, they will be offered to participate. A complete count of screened, eligible, and included participants will be detailed in the final report of the study. Eligibility: As described in the next section, cases must meet all the inclusion criteria, and none of the exclusion ones.

You may qualify if:

  • Absence of flow at the pulmonary valve (PA) or presence of thickened and domed. pulmonary valve cusps with a pinhole jet of flow.
  • Doppler evidence of ductal-dependent pulmonary circulation.
  • Intact ventricular septum.

You may not qualify if:

  • Poor imaging windows and incomplete/poor quality scan
  • Termination of pregnancy
  • Cases initially included that undergo prenatal pulmonary valvuloplasty later on in pregnancy.
  • Unconfirmed PA-CS/IVS at birth.
  • Functional PA-CS/IVS (Ebstein malformation, monochorionic twins)
  • Any associated cardiac defect except persistent left superior vena cava and aberrant right subclavian artery.
