Coronary CT angiography may help predict if patient needs invasive coronary angiography
Delhi: Coronary CT angiography (CCTA) is a promising tool for helping clinicians determine if a patient needs invasive coronary angiography, finds a recent study. Also, CCTA could be used for planning strategies for managing coronary interventions for treating the disease. The study was published online in the journal Radiology: Cardiothoracic Imaging on January 6, 2022.
CCTA emerges as a powerful non-invasive tool for characterizing the extent, presence, and severity of coronary artery disease (CAD) in stable angina patients. Recent advancements in CT scanner hardware and software can generate more useful clinical information from a single study, Jonathon A. Leipsic, Cardiovascular Center Aalst, OLV Clinic, Aalst, Belgium (N.M., J.S., C.C.), and colleagues noted in their study.
"Beyond merely identifying the presence of CAD and assessing stenosis severity, CCTA now allows for the identification and characterization of plaques, lesion length, and fluoroscopic angle optimization, as well as enables the assessment of the physiologic extent of stenosis through CT-derived fractional flow reserve, and may even allow for the prediction of the response to revascularization," wrote the authors. "These along with features make CCTA capable of giving the unique ability to help plan coronary intervention and guiding coronary angiography referral."
The paper has summarized current and future applications of CCTA in procedural planning for percutaneous coronary intervention, provides rationale for wider integration of CCTA in the workflow of the interventional cardiologist, and details how CCTA may help improve patient care and clinical outcomes.
"Coronary CT angiography could be used as a tool to guide referral for invasive coronary angiography, as well as to help plan coronary intervention," concluded the authors. "The potential of CCTA needs to be further explored in prospective trials to evaluate to what extent this modality may enable more efficient catheterization laboratory use, more complete revascularization, and improved clinical outcomes."
