About this study

Official title: Pharmacological Test of Pulmonary Endothelium-dependent Vascular Reactivity to Acetylcholine in Pulmonary Arterial Hypertension With Congenital Cardiac Shunt Child and Adult

The purpose of this study is to assess the predictive performance of the pulmonary vascular reactivity to acetylcholine, in the presence pulmonary arterial hypertension (estimated 1 year after the closure of the shunt).

Read the detailed description

Pulmonary arterial hypertension (PAH) is an important cause of mortality and morbidity in patients with congenital heart disease with a shunt.

These congenital cardiac shunts are responsible for PAH, which evolves towards higher pulmonary vascular resistance if they are not closed early.

Patients with significant pulmonary flow and low pulmonary vascular resistance fully benefit from surgical shunt closure with complete disappearance of pulmonary hypertension after closure. In contrast, patients with low pulmonary flow and high pulmonary vascular resistance will have no benefit because they keep a deleterious pulmonary hypertension after closure of the shunt.

In certain situations, especially late discovery of heart disease, the issue of operability of these patients is crucial because closing the shunt inappropriately worsens the spontaneous prognosis. Currently, in case of doubt on the operability, there are several clinical and hemodynamic criteria used empirically, but their predictive value is uncertain.

It is therefore necessary to stratify patients into operable and inoperable groups to improve their overall outcome after surgery.

In this research project we propose to assess the predictive performance of the pulmonary vascular reactivity to acetylcholine test on the presence of elevated PAH 1 year after the closure of the shunt. This reactivity test will be evaluated on a population of patients for whom the decision of the surgical closure of the shunt has been adjudicated on the basis of explorations and usual tests (and therefore blind to the knowledge of the result of the reactivity test). The test in this study is designed with repeated injections and increasing doses with a continuous flow of acetylcholine in the left lower lobe of the pulmonary artery. The last injection consisted with adenosine with inhaled O2/NO (potentiating effect) for maximum vasodilatation. The parameter of interest is the Doppler flow velocity in the pulmonary artery endothelium-dependent vasodilation by acetylcholine relative to the speed at maximum vasodilatation (adenosine + in nitric oxide (NO) inhalation)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Predictive performance of the reactivity test to the occurence of pulmonary arterial hypertension one year after the closure of the shunt.

    Evaluated in patient with "shunt closed" by :

    • the area under the ROC curve.
    • the parameter of interest is the Doppler flow velocity in m / s in endothelium-dependent vasodilation by acetylcholine relative to the speed in m / s at maximum vasodilatation (adenosine + in nitric oxide (NO) inhalation)
    • presence or absence of PAH one year after closure of the shunt will be evaluated by a conventional cardiac catheterization

    Measured: 1 year +/- 2 months

Secondary outcomes (3)
  1. occurrence of pulmonary hypertension.

    Measured: 1 year +/- 2 months

  2. Nature and frequency of adverse events

    Measured: 1 year +/- 2 months

  3. Characteristic of the distribution of test of reactivity in the population "shunt unclosed"

    Measured: 1 year +/- 2 months

Questions about this trial

What is this clinical trial studying?

A study testing Pharmacological test of pulmonary endothelial in people with Pulmonary Arterial Hypertension With Congenital Cardiac Shunt, run by Assistance Publique - Hôpitaux de Paris.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 8 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Predictive performance of the reactivity test to the occurence of pulmonary arterial hypertension one year after the closure of the shunt. (time frame: 1 year +/- 2 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2026.
