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 Results may not be published yet.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

Summary

This study measured the amount and type of waste produced during heart procedures like angiograms and valve repairs. Researchers weighed and sorted waste into categories such as paper, regular trash, medical waste, and recyclable plastic. They compared two waste-handling methods to see which is better for the environment and costs. The goal is to help hospitals reduce their environmental footprint.

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 help hospitals reduce waste and carbon emissions from heart procedures, making them more eco-friendly and cost-effective.
What could go wrong
This is a small, completed observational study with 40 patients. Results may not apply to all hospitals or countries, and it does not test any treatment.

The study "population" includes the following interventional procedures on scheduled audit days: (i) elective diagnostic coronary angiography with or without simple PCI, (ii) complex PCI procedures, including CTO, CHIP, or patients in cardiogenic shock requiring temporary mechanical circulatory support with an Impella device, (iii) TAVI, and (iv) TEER of the mitral or tricuspid valves, such as with MitraClip or TriClip systems. A minimum of ten cases per procedure type will be targeted to ensure adequate comparisons. All patients undergoing the above-listed procedures during the defined measurement days are eligible for inclusion
