  Fig. 1. Transthoracic echocardiography (TTE), parasternal long-axis view showing (A) dilated coronary sinus (CS; white arrow) and right coronary artery (RCA; yellow arrow), (B) aliasing signal at the CS on color Doppler imaging, and (C) continuous flow on pulse-wave Doppler imaging. TTE, subcostal view showing (D) the dilated CS ostium (white arrow) and RCA (yellow arrow), and (E) blood flow from the CS ostium to the right atrium on color Doppler imaging. (F) Turbulent blood flow from the CS ostium (white arrow) was observed by transesophageal echocardiography.

  Fig. 2. Transthoracic echocardiography (TTE), parasternal long-axis view showing (A) immediate opacification of the right ventricle (RV), not of the coronary sinus (CS), after injection of agitated saline into a left arm. Cardiac computed tomography (CT), axial imaging, and three-dimensional volume-rendering imaging presenting (B–F) dilated right coronary artery (RCA), fistula (white arrow), and dilated CS. Cardiac CT, multiplanar reformatting imaging presenting (D) the overall course of huge RCA with fistula to the CS. Coronary angiography presenting (G) dilated, tortuous RCA drained to the right atrium.
