Side matters: An intriguing case of persistent left superior vena-cava

Figure 1 Ultrasonography. A: Modified apical 4 chamber two-dimensional echocardiographic view showing dilated coronary sinus; B: Injection of agitated saline into the left antecubital vein results in filling of the coronary sinus first (star), followed by the filling of the right atrium. CS: Coronary sinus; LV: Left ventricle; RA: Right atrium; RV: Right ventricle.
