Cardiol Young

January 2025

Congenital Heart Center, Division of Pediatric Cardiology, Department of Pediatrics, University of Florida, Gainesville, FL, USA.

Purpose: High takeoff of the right coronary artery suspected by echocardiography is widely considered a normal variant. However, in our experience, some patients initially thought to have a high takeoff of the coronary artery were later found to have an anomalous coronary origin with high-risk features. The aim of this study was to test the hypothesis that high takeoff of the right coronary artery suspected by echocardiography may indicate the presence of an anomalous coronary artery lesion with an intramural course requiring further investigation.

Nuclear Cardiology Surrogate Biomarkers in Clinical Trials.

J Nucl Med

January 2025

Departments of Medicine (Division of Artificial Intelligence in Medicine), Imaging, and Biomedical Sciences, Cedars-Sinai Medical Center, Los Angeles, California;

Nuclear cardiology offers a diverse range of imaging tools that provide valuable insights into myocardial perfusion, inflammation, metabolism, neuroregulation, thrombosis, and microcalcification. These techniques are crucial not only for diagnosing and managing cardiovascular conditions but also for gaining pathophysiologic insights. Surrogate biomarkers in nuclear cardiology, represented by detectable imaging changes, correlate with disease processes or therapeutic responses and can serve as endpoints in clinical trials when they demonstrate a clear link with these processes.
