About this study
Official title: Efficacy of Fluoroscopy-save Function During Cardiac Catheterization
The aim of this study is to evaluate the effects of screening using the fluoroscopy-save function on reduction of radiation exposure and quality of angiogram during cardiac catheterization when compared to traditional cinematography-guided coronary angiography.
Read the detailed description
The study will be a prospective, randomized study of patients undergoing clinically-indicated coronary angiograpy in the New York University (NYU) Langone Medical Center cardiac catheterization laboratory. Patients will be randomized to one of two coronary angiography protocols: (1) Coronary anatomy visualized under fluoroscopy, documented using the fluoroscopy-save function, and further visualized using cinematography only when higher quality is necessary (fluoroscopy-save technique) versus (2) Coronary anatomy visualized and documented using cinematography alone (standard technique). The primary outcome will be a measure of radiation exposure to the patient, surface peak skin dose, as measured by the Gafchromic XR RV3 film strip, which is placed under the patient's back during the procedure. Other outcome measures will include radiation output recorded by the fluoroscopy machine, amount of contrast used, and quality of angiograms performed. To determine if the quality of the angiograms performed using the fluoroscopy-save technique is non-inferior to the standard technique, one extra picture will be taken at random using the mode that the study was not randomized to. For example, in the fluoroscopy-save group, a picture that was not visualized under cinematography during the study will be repeated and documented under cinematograpy. In the standard group, a picture will be repeated and documented using the fluoroscopy-save function. These 2 pictures from each study will then be collated and put together in no particular order with all identifiers removed. These single pictures will be read by 2 interventional cardiologists not involved in the study in a blinded fashion. The degree of coronary artery disease as determined by these 2 readers will be compared between the fluoroscopy-save picture and cinematography picture.

What is being measured
The primary outcome is the main question the study is designed to answer.
Measure of radiation exposure to the patient
Surface peak skin dose, as measured by the Gafchromic XR RV3 film strip, which is placed under the patient's back during the procedure.
Measured: During coronary angiography
Secondary outcomes (3)
Dose area product from coronary angiography system
Measured: During coronary angiography
Quality of angiograms
One extra picture will be taken at random using the mode that the study was not randomized to. These 2 pictures from each study will then be collated and put together in no particular order with all identifiers removed. These single pictures will be read by 2 interventional cardiologists not involved in the study in a blinded fashion and degree of correlation between the fluoroscopy-save picture and cinematography picture will be recorded.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Fluoroscopy-save group and Standard technique in people with Coronary Artery Disease, run by NYU Langone 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 1 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: finished, as of the sponsor's last update on 15 Oct 2012. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Measure of radiation exposure to the patient (time frame: During coronary angiography). 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 15 Oct 2012.
