Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Adult, Older adult

Study population: Consecutive patients referred to our cath lab for clinically indicated coronary angiography or right heart catheterization for the diagnosis of dyspnea

Who may be able to join

  • ≥ 18 yo,
  • Signed informed consent to be part of this study,
  • No pregnancy,
  • Good acoustic window and patient cooperation to obtain good 2- and 3-dimensional datasets focused on left atrium (LA),

Who cannot join

  • Unwillingness to be part of the study,
  • Patients with poor 2-dimensional imaging quality in ≥ 1 LA segment or lacking of a discernible R-R interval, which might preclude accurate strain measurements,
  • Patients with more than mild mitral valve heart disease, aortic regurgitation, left side valvular prosthesis or mitral valve repair, mitral annulus calcification (≥ 5 mm),
  • Patients with history or presence of atrial fibrillation (AF), supraventricular arrhythmias, ventricular paced rhythm, left bundle branch block (LBBB),
  • Patients taking diuretics or vasodilators (nitrates) on the day of the examination, which could alter loading conditions.

About this study

Official title: Valutazione Delle Pressioni di Riempimento Del Ventricolo Sinistro Attraverso l'Impiego di un Software di Intelligenza Artificiale Applicato Alla Stima Dello Strain Atriale Sinistro Con Ecocardiografia Speckletracking: Studio di Validazione Mediante Cateterismo Cardiaco

The goal of this single-center, prospective, observational study is to validate a software package based on an artificial intelligence algorithm for automated non-invasive estimation of LVFP against invasively measured ones by left and right heart catheterization; In addition, the added value of this new automated software to detect increased LVEDP > 15 mm Hg compared to the current ASE/EACVI algorithm for assessing diastolic dysfunction and longitudinal left atrial strain during the reservoir phase will be evaluated.

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure, Diastolic and Echocardiography, run by Istituto Auxologico Italiano 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 4 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: status not confirmed, as of the sponsor's last update on 16 Apr 2024. 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?

Results are not available in the source record.

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

Contact Luigi Badano, MD, Ph.D. (+390261911 ext. 2319, l.badano@auxologico.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Left ventricular filling pressure (time frame: During procedure). 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 16 Apr 2024.
