A Rare Coincidence of Two Coronary Anomalies in an Adult

Figure 2

Short LADCA (hypoplastic) arising from the left sinus of Valsalva by CTA and selective coronary angiography.

(a) Demonstration of the course of the short LADCA on the anterior interventricular septum by curved multiplanar reconstruction (black arrow). Note that it terminates in the proximal third of the interventricular septum and does not give any branches. The heavily calcified LCX artery is seen coursing on the AV groove (white arrow)

(b) Anteroposterior projection of the hypoplastic LADCA arising from the left sinus of Valsalva (arrow)

(c) Three-dimensional reconstruction showing the short LADCA on the proximal third of the anterior interventricular sulcus (IVS) (large white arrow) and the LMCA emerging from the septum and dividing into the long LADCA which travels along the second and distal third of the IVS (black arrow) and left circumflex artery coursing in the atrioventricular groove (short white arrow)
