1. Introduction: When the Heart’s Map is Different
The human heart typically follows a precise architectural plan, with coronary arteries (CAs) emerging from specific locations to deliver oxygenated blood to the cardiac muscle. However, in some individuals, the heart’s map is drawn differently from birth. These variations are known as Congenital Coronary Artery Anomalies.
As a pediatric cardiologist and educator, I emphasize to families that while many of these variations are benign, identifying them is a matter of life and death. These anomalies are the second leading cause of sudden cardiac death in young athletes. Historically, diagnosing these "hidden pathways" required invasive cardiac catheterization. Today, advanced imaging—specifically Echocardiography, Cardiac Computed Tomography (CCT), and Cardiac Magnetic Resonance (CMR)—has replaced invasive tools as the primary method for safe and accurate diagnosis.
2. The Diagnostic Toolkit: How We See the Heart
Modern pediatric cardiology utilizes a multimodality imaging strategy to visualize complex coronary anatomy. Each modality offers unique technical advantages.
