Clinical definition (Orphanet)

Premature closure of the arterial duct is a rare arterial duct anomaly, defined as a significant constriction or closure of the fetal arterial duct in the absence of structural heart defects with pathognomonic features of increased right ventricular afterload, tricuspid regurgitation and, consequently, right atrial dilation and right ventricular hypertrophy. The severity of symptoms is related to the degree and rate of ductal constriction and ranges from mild postnatal respiratory distress to development of ventricular failure with fetal hydrops and intrauterine death or severe cardiopulmonary compromise in the postnatal period. It may be associated with a exposure to cyclooxygenase inhibitors or corticosteroids.

Trial readiness signals

Where this condition sits on an open-data research pipeline — not how close a treatment is, and not medical advice. Empty stages often mean “not in these databases under this Mondo ID,” not “impossible.”

Biology

Genes and phenotypes

Gene–disease validity from GenCC, plus phenotypes and animal models joined from Monarch Initiative via Mondo ID — not a clinical diagnosis aid.

Do we know what causes it?

Not yet — the cause hasn't been pinned down in GenCC.

No strong gene–disease assertion joined for this Orphanet entity.

Where to find support

We do not yet link condition-specific patient organisations. These umbrella groups support undiagnosed and ultra-rare families:

India — NPRD

Last verified 2026-07-26

This ORPHAcode is not on our curated NPRD list (direct or Mondo-parent match). That does not decide clinical eligibility; families in India should ask a notified Centre of Excellence about current coverage.

Hand-curated for this project. ORPHAcode mappings are best-effort and may be incomplete or imprecise for umbrella categories. Parent (Mondo) matches mean the policy lists a broader category — confirm eligibility with a Centre of Excellence. Financial entitlements summarised from public policy statements and may change. This is not official government guidance.
