What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested a new X-ray-based imaging tool called 3DStent against the standard IVUS method to measure calcium buildup in heart arteries. Thirty adults with coronary lesions were enrolled. The goal was to see if 3DStent can accurately identify and measure calcium deposits, which could lead to quicker and less invasive assessments during heart procedures.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to a simpler, faster way to measure calcium buildup in heart arteries, helping doctors plan better treatments.
What could go wrong
This is a small pilot study with only 30 participants, so results may not apply to everyone. The 3DStent method is still experimental and may not be as accurate as IVUS.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Male or female aged 18 years or older * Patient with a coronary lesion. * Angiographically calcified culprit lesion (Mintz classification) 1 Moderate: lesion with radiopaqueness noted only during the cardiac cycle before contrast injection Severe: lesion with radiopaqueness seen without cardiac motion before contrast injection, visible on both sides of the arterial lumen * Ability to traverse the culprit lesion with an IVUS catheter * Having been informed by an investigator about the research topic and having given their free, explicit, and informed consent. * Affiliation with a social security scheme (beneficiary or dependent) Exclusion Criteria: * Acute coronary syndrome of the ST-segment elevation myocardial infarction type * Progressive cardiogenic shock * Culprit lesion impassable with an IV catheter * Pregnant, parturient, or breastfeeding women and other vulnerable categories: legally incapacitated adults, adults unable to express their consent and not subject to a protective measure, persons deprived of their liberty * BMI \> 35 kg/m²
