Trial summary

The investigators aim to correlate noninvasive pulmonary artery systolic pressure (PASP) measurements obtained with and without echocardiographic contrast (Optison) during transthoracic echocardiography (TTE) with those obtained invasively and simultaneously during right heart catheterization, as the gold standard.

About this study

Official title: The Role of Echocardiographic Contrast (Optison) in Enhancing Tricuspid Regurgitation Spectral Doppler Signals to Assess Pulmonary Artery Systolic Pressures. Correlation With Invasive Measurements Obtained by Right Heart Catheterization

The investigators aim to correlate noninvasive pulmonary artery systolic pressure (PASP) measurements obtained with and without echocardiographic contrast (Optison) during transthoracic echocardiography (TTE) with those obtained invasively and simultaneously during right heart catheterization, as the gold standard.

Read the detailed description

In the United States, pulmonary hypertension (PHT) is an increasingly recognized cause of morbidity and mortality.

Echocardiography, due to its widespread use, versatility, portability, noninvasive nature, and safety, is routinely used as the primary method for diagnosis and evaluation of these patients. However, in this very cohort, its accuracy is frequently compromised by poor acoustic windows. The use of echocardiographic contrast (EC) in such patients may increase diagnostic accuracy, eliminate the need for performing more invasive, time-consuming, and expensive tests, and eliminate potential diagnostic and management errors.

Pulmonary Artery Systolic Pressure (PASP) is routinely measured noninvasively with transthoracic echocardiography (TTE) by obtaining the tricuspid regurgitant velocity (TRV) with continuous wave spectral Doppler and applying the modified Bernoulli equation.

The investigators aim to use the FDA approved perflutren-based EC agent Optison to augment inadequate TR CW spectral Doppler envelopes and determine if the TRV and PASP measurements obtained with the use of Optison correlate better with the invasive measurements obtained simultaneously during right heart catheterization as opposed to those measurements obtained without the use of EC.

What is being measured

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

  1. Noninvasively derived PASP values in patients with versus without Optison enhanced TR continuous wave (CW) spectral Doppler envelopes in patients with technically inadequate studies to PASP measurements obtained invasively and simultaneously

    Measured: up to 6 months

Secondary outcomes (3)
  1. Continuous wave PASP Doppler Envelope measurements in patients receiving Optison versus conventional non-perflutren based agents (10% air-90% saline mixture).

    Compare the diagnostic role of Optison versus conventional non-perflutren based agents (10% air-90% saline mixture) in enhancing inadequate TR continuous wave spectral Doppler envelopes. This will be done by measuring the values obtained from echocardiographic and invasive hemodynamics with respect to PASP.

    Measured: up to 6 months

  2. Invasive hemodynamic values in patients who undergo perflutren based EC (Optison) administration on PASP values in patients with normal or elevated PASP.

    Measured: up to 6 months

  3. Number of patients with adverse events as a measure of safety

    Measured: up to 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Hypertension, Pulmonary, run by Northwell Health at 1 site in United States.

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 2 inclusion and 5 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 21 Jan 2016. 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 United States. 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?

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?

Noninvasively derived PASP values in patients with versus without Optison enhanced TR continuous wave (CW) spectral Doppler envelopes in patients with technically inadequate studies to PASP measurements obtained invasively and simultaneously (time frame: up to 6 months). 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 NCT02560116, 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 21 Jan 2016.
