About this study

Official title: Outcome of Balloon Pulmonary Valvuloplasty in Patients With Congenital Pulmonary Stenosis in Terms of Reverse Right Ventricular Remodeling and Functional Exercise Capacity

A prospective of 30 patients with symptomatic severe congenital valvular pulmonary stenosis who are indicated for percutaneous balloon pulmonary valvuloplasty . the aim is to

  1. - evaluate electrical and mechanical remodeling of RV 6 months following balloon dilation
  2. - evaluate Functional capacity using 6MWT and SaO2 before and 6 months following BPV
Read the detailed description

Valvular pulmonary stenosis (PS), defined as an obstruction of blood flow at the level of the pulmonary valve, is a form of congenital heart disease, described in 0.6-0.8 out of 1000 live births.

The main physiologic effect of valvular pulmonary stenosis (PS) is an increase in Right ventricular pressure proportional to the severity of obstruction. This elevation of RV pressure is accompanied by an increase in muscle mass where hyperplasia of the muscle cells with a concomitant increase in the number of capillaries occurs. In contrast, the adult myocardium responds with hypertrophy of the existing fibers, with no change in the capillary network. Percutaneous balloon pulmonary valvuloplasty (PBPV) is the procedure of choice for uncomplicated severe or symptomatic pulmonary stenosis. the aim is to

  1. - evaluate electrical and mechanical remodeling of RV 6 months following balloon dilation
  2. - evaluate Functional capacity using 6MWT and SaO2 before and 6 months following BPV

Questions about this trial

What is this clinical trial studying?

An observational study of Congenital Heart Disease and Pulmonary Valve Stenoses, run by Assiut University at 1 site in Egypt.

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 1 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 25 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

reverse Right ventricular remodeling (time frame: one year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05828524, which also lists 5 linked publications.

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 25 Apr 2023.
