The RCA followed its normal course around the atrioventricular groove and the LMCA traveled to the left side of the heart and divided at the level of the interventricular septum giving off a long LADCA and the LCXCA (Figure 1). CTA demonstrated the LMCA traveling to the left side of the heart behind the right ventricular outflow tract and through the interventricular septum (Figures 1 and 2).

Selective left coronary angiography with a 6F left Judkins 3.5 catheter revealed a second short hypoplastic LADCA that ended at the distal end of the proximal third of the interventricular sulcus without giving any branches of significant size (Figure 2). CTA demonstrated the LMCA traveling to the left side of the heart behind the right ventricular outflow tract and through the interventricular septum (Figures 1 and 2).
