Overview

The diagnostic hypothesis is based on the evidence that, while the functional closure of the PDA (Patent Ductus Arteriosus) occurs within a few hours after birth, anatomical closure may take several weeks. The functional closure of the PDA can be extremely sensitive to variations in blood oxygen tension and the hemodynamic instability of preterm infants. Therefore, echocardiographic evaluation and ductal diameter at a single point in time (such as during PDA echocardiography) may not correlate with transductal blood flow. Assessing the variation in the amount of pulmonary interstitial fluid using LUS (lung ultrasound score) could be an early predictive parameter for the closure or non-closure of hsPDA (hemodynamically significant PDA).

Eligibility

Inclusion Criteria:

  • Neonates under 28 days of life
  • Patients eligible for hsPDA closure treatment according to standard clinical practice

Exclusion Criteria:

  • Neonates with congenital heart diseases (except for PDA and patent foramen ovale)
  • Neonates with pneumothorax
  • Neonates with pulmonary hemorrhage

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
