Figure 4 (A–C) Invasive coronary angiography demonstrating anomalous origin of the left circumflex (LCx) artery from the right sinus of Valsalva. In Figure 4A and 4B, the left main coronary artery continues directly as the left anterior descending artery without giving rise to the LCx artery; severe stenosis is present in the mid-segment of the right coronary artery. Figure 4C shows the coronary angiographic image after treatment. The arrow indicates the Firebird2 Rapamycin-Eluting Coronary Stent System, and the right coronary artery is well expanded following stent implantation.
