Abstract

Purpose of Review

Comprehensive discussion of alternative techniques in imaging coronary artery anomalies (CAAs) in different diagnostic scenarios.

Recent Findings

At primary screening, intramural course essentially correlates with stenosis and clinical repercussion in some types of CAAs. Potential clinical aims in imaging patients with CAAs may be primary screening, severity evaluation, preoperative planning, and postoperative follow-up. Appropriate techniques are echocardiography, magnetic resonance imaging, computed tomography angiography, and intravascular ultrasound (IVUS). Rarely, IVUS may be needed in patients with potentially serious CAAs and has unique advantages and limitations. IVUS data are essential for in-depth knowledge of mechanisms of coronary dysfunction (exercise-related dynamic stenosis of variable severity) and for indicating interventional treatment.

Summary

In adolescents or adults, intramural course of an anomalous coronary artery is the only important feature accompanied by stenosis of potential severity and is especially relevant in patients with a high-risk status (elite sport athletes, military recruits).
