CCTA-guided Ultraselective Invasive Coronary Angiography
Coronary Computed Tomography Angiography Guidance in Invasive Coronary Angiography; a Prospective Registry Study
Coronary artery disease (CAD) is the leading cause of death in adults in the United States.[1] In the latest guidelines of the European Society of Cardiology anatomical non-invasive imaging by coronary computed tomography angiography (CCTA) plays an important role in the diagnosis of the presence of CAD in patients without a history of CAD and a low to intermediate likelihood.[2] CCTA provides high accuracy for the detection of coronary artery disease by visualizing the coronary artery lumen using an intravenous contrast agent.[3] However to determine the hemodynamical significance of CCTA-identified stenosis, invasive coronary angiography (ICA) with or without functional testing is still required. [4] During the ICA as per protocol the complete coronary artery system is visualized again. In patients with abnormalities on CCTA in only one coronary artery, i.e. only the left coronary artery (LCA) or the right coronary artery (RCA), the ICA procedure might be simplified by 'ultraselectively' visualizing only the coronary artery of interest and refraining from angiographic visualization of the contralateral coronary artery without abnormalities on CCTA (with an excellent negative predictive value of 95-99%).[5-7] Such an ultraselective strategy might reduce procedure time, usage of catheters, complication risk and the amount of contrast agent and radiation exposure.
A recent retrospective study in three hospitals in the Netherlands showed CCTA to be extremely accurate in predicting a normal contralateral coronary artery in patients with coronary artery disease limited to the left or right coronary artery. Therefore, a CCTA-guided ultraselective ICA approach would have been safe and feasible and would have led to a considerable decrease in procedure time and radiation exposure.
However, the analysis was hampered by the retrospective design. The potential benefits in salvage of procedure time and radiation exposure might be overestimated and it turned out to be impossible to measure the effects on contrast use, catheter use and procedure costs. Moreover, in the retrospective study only a small portion of the study population had abnormalities in the right coronary artery, thereby questioning the results of this study to safely be extrapolated to this category of patients with abnormalities in the RCA.
This dual-center prospective registry study is designed to answer these remaining questions and to further investigate the potential benefit of an ultraselective ICA approach.

Study design & patient population
The study is a dual-center prospective registry in two hospitals in the Netherlands. All patients eligible for participation in this registry are aged 18-80 years old and undergoing invasive coronary angiography because of abnormalities found on CCTA in either the left or right coronary artery and no or minimal stenosis (CAD-RADS 0-1; 0-24% stenosis) in the contralateral coronary artery.
Patients will be asked for written informed consent to register their clinical data in an anonymized database. The period between CCTA and ICA may not exceed 90 days, in order to prevent possible aggravation of coronary artery disease between both examinations.
Clinical characteristics (age, gender, risk factors, relevant medical history) and CCTA data will be included in the database. All procedural characteristics and findings of the invasive coronary angiography procedure will be logged, including access site, procedural planning (which coronary artery to be visualized first), procedure duration, amount and type of catheters used, amount of radiation exposure and contrast volume, procedural findings, type of coronary intervention (if applicable), and complications. Procedure duration is defined as the time needed for the diagnostic part of the ICA procedure, possible further functional invasive testing and/or percutaneous coronary intervention is excluded. ICA data will be compared to the CCTA data on a per-patient level. No further follow-up is planned after the invasive coronary angiography with regards to participating in this registry.
Informed consent
If patients provide informed consent, the data will be registered in an anonymized database. Patients can withdraw from this study at any time at their own request, or they may be withdrawn at the discretion of the investigator for behavioral, or administrative reasons. The reason(s) for discontinuation will be documented and may include: the subject voluntarily withdraws from registry.
Since the patients will not be subjected to any additional procedures, rules or behavior and the data will be anonymized, we believe this research design does not fall under the scope of the Medical Research Involving Human Subjects Act (WMO).
Database and data protection
Data will be stored anonymized in an online database and will only be accessible to the involved researchers. Personal data will comply to the Dutch Personal Data Protection Act. Site investigators will only be able to add patients from their own site, and will only be able to see patients from their own site. Data generated will be encoded and a separate patient identification log will be created for each site, and stored at each site separately. The key to the code will be available to specific site investigators only. There will be at least one study coordinator that has access to all records of all sites. In the future data from other centers could be included into the database using this similar pattern to ensure data protection.
