Transthoracic echocardiography in the parasternal short-axis view showing a right coronary artery aneurysm (Panel A, white arrow) and a left main coronary artery aneurysm (Panel A, red arrow). The proximal portion of the right coronary artery (Panel B, white arrow) has a diameter of 4.1 mm (Z-score +7.4), while the distal portion of the right coronary artery (Panel C, white arrow) has a diameter of 4.7 mm (Z-score +7.8). The left main coronary artery bifurcation (Panel D, red arrow) measured 3.9 mm (Z-score +4.9), while the proximal left anterior descending artery (Panel E, red arrow) measured 4.7 mm (Z-score +8.1).
