Trial summary

To investigate the long term functional capacity and quality of life of patients with a history of vascular ring whether they did or did not have corrective surgery. Patients will perform pulmonary function test, 6 minute walk test, cardiopulmonary exercise test and will fill a quality of life questionnaire. Read more about this study

About this study

To investigate the long term functional capacity and quality of life of patients with a history of vascular ring whether they did or did not have corrective surgery. Patients will perform pulmonary function test, 6 minute walk test, cardiopulmonary exercise test and will fill a quality of life questionnaire.

Read the detailed description

Vascular rings are congenital vascular anomalies of the aortic arch that compress the esophagus and the trachea. The most common vascular rings are double aortic arch and right aortic arch with left ligamentum. Pulmonary artery sling is less common. Another cause of tracheal compression occurring only in infants is the innominate artery compression syndrome. When patients are symptomatic, surgical correction should be performed.

data regarding long term functional capacity and quality of life is lacking. our aim is to investigate the long term functional capacity and quality of life of patients with history of vascular ring whether they did or did not have corrective surgery.

Methods: a prospective study evaluating functional capacity and quality of life the patients will perform pulmonary function test, 6 minute walk test, cardiopulmonary exercise test and will fill a quality of life questionnaire (sf-36).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cardiopulmonary exercise testDiagnostic test

    Also called 6 minute walk test, quality of life questionnaire (sf-36)

    CPET using a cycle ergometer (COSMED, Rome, Italy) beginning with no resistance warmup lasting 1-3 minutes followed with an incrementing resistance adapted to the patient's functional capacities according to the examiner's free judgment by successive stages

    Six minute walk test - patients will be instructed to walk as far as possible for six minutes in a 30-meter long enclosed corridor with a flat and hard surface, marked at every meter. Meters will be calculated at the end of the test.

    SF-36 is a questionnaire that contains eight domains - physical functioning (10 items); role limitations due to physical functioning (4 items); role limitations due to emotional problems (3 items); energy and vitality (4 items); mental health (5 items); social functioning (2 items); bodily pain (2 items); and general health perceptions (5 items).

    Scores are summed for each domain and were transformed into scores of between 0 (worst possible health state) to 100 (best possible health state).

What is being measured

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

  1. Exercise capacity

    Oxygen uptake evaluated by cardiopulmonary exercise testing (CPET)

    Measured: Measured continuously during 15 minutes of the exercise test (CPET)

Secondary outcomes (2)
  1. Six minute walk test

    The distance gained after six minute of habitual walking.

    Measured: Six minutes of evaluation, completed pre cardiopulmonary exercise test (CPET)

  2. Quality of life - SF-36

    The calculated result of SF-36 questionnaire

    Measured: Five minutes of evaluation, completed pre cardiopulmonary exercise test (CPET)

Questions about this trial

What is this clinical trial studying?

An observational study of Vascular Ring, run by Rambam Health Care Campus at 1 site in Israel.

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 2 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 4 Mar 2021. 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 Israel. 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?

Contact Lea Bentur, MD (+972-4-7774360, l_bentur@rambam.health.gov.il), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Exercise capacity (time frame: Measured continuously during 15 minutes of the exercise test (CPET)). 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 NCT04781738, which also lists 1 linked publication.

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 4 Mar 2021.
