Researchers at Asan Medical Center, South Korea's largest hospital, have pioneered an AI-based system that effectively analyzes coronary artery images prior to coronary angioplasty—a vital procedure for treating coronary artery disease. This groundbreaking study is the first to validate the safety of an AI-guided approach in a clinical setting, offering a beacon of hope for more efficient cardiac interventions.
Findings
The innovative AI system developed by the Asan research team assists cardiologists during cardiovascular angiography, which is crucial for assessing a narrowed artery and determining the correct stent size. Once an angiogram is uploaded to the system, the AI evaluates critical metrics like internal diameter, lesion length, and degree of stenosis. Based on this data, it calculates the optimal stent size needed for effective intervention.
In a robust study published in the Journal of the American College of Cardiology, the researchers conducted a comparative analysis involving nearly 400 patients across 13 medical institutions. They found that AI-assisted treatments produced safety outcomes on par with those guided by traditional, more expensive 3D imaging methods. Notably, the AI system recorded no major adverse clinical events such as death, myocardial infarction, or thrombosis during the procedures.
Why It Matters
While 3D high-resolution imaging—specifically intravascular optical coherence tomography—is recognized as the gold standard for evaluating artery lesions, its cost and time demands often deter clinicians from using it. The Asan research team is advocating for their AI system as a faster, more objective alternative that offers comparable safety without significant extra time or labor costs.
Jung-min Ahn, AMC professor and study lead, emphasizes the transformative potential of AI on coronary angiography, stating, “Using AI, coronary angiography images can be analyzed quickly and objectively without additional time or labor, making coronary intervention possible without error.” The researchers are now eyeing an expansion of this technology to include more complex coronary artery lesions.
Market Snapshot
While this advancement is a groundbreaking first in validating the safety of AI in cardiac angiography, it isn't the only integration of AI in this domain. For instance, companies such as Cleerly in the United States and Caristo Diagnostics in the United Kingdom have already deployed AI technologies to assess CT angiograms for heart disease diagnosis. Similarly, the Australian company Artrya has developed Salix, an AI tool that evaluates atherosclerotic plaque in heart CT scans, which has secured regulatory approval in Europe and the UK.
Conclusion
As the landscape of cardiac care continues to evolve with technology, the work being done by Asan Medical Center sets new standards for safety and efficiency in cardiovascular procedures. With plans for further developments and applications, AI could fundamentally change how medical imaging is utilized in clinical practice, giving rise to a new era of patient care.
