Standard method for ultrasound imaging of coronary artery in children

Area of Science:

• Pediatric Cardiology
• Diagnostic Imaging
• Echocardiography

Background:

• Kawasaki disease is a critical pediatric condition affecting coronary arteries.
• Accurate measurement of coronary artery diameter is essential for diagnosis and management.
• Standardized ultrasound techniques are needed for reliable pediatric coronary artery assessment.

Purpose of the Study:

• To establish standardized ultrasound imaging protocols for measuring coronary artery diameter in children.
• To provide reference guidelines for pediatric echocardiography of coronary arteries.

Main Methods:

• Utilizing sector probe ultrasound (≥ 5 MHz) with patients in supine or right decubitus positions.
• Measuring coronary arterial diameter between internal echo edges at minimum gain during early diastole (end of T wave).
• Employing specific anatomical approaches for visualizing left main, right, and anterior descending coronary arteries via precordial short axis and atrioventricular/interventricular grooves.

Main Results:

• Detailed anatomical landmarks and imaging planes are described for optimal visualization.
• Specific probe positions and patient orientations are recommended for consistent measurements.
• The technique allows for comprehensive assessment of major coronary artery segments.

Conclusions:

• Ultrasound imaging is the recommended standard for pediatric coronary artery diameter measurement.
• Standardized methodology ensures accurate and reproducible assessments.
• This approach aids in the early detection and monitoring of coronary artery abnormalities in children.
