Figure 4. The yellow arrow shows the route through the moderator band and the blue arrow shows the reverse cart in the proximal RCA.
RCA: right coronary artery
Figure 5. Pervious RCA with 3 Xience Alpine stents 3.0 mm × 38 mm. RCA: right coronary artery
To the best of our knowledge, this is the first case report of a retrograde approach using the moderator band
artery as source of collaterals to open a RCA CTO.
In conclusion, the retrograde route described above could be useful for CTO RCA cases after antegrade
failure and when standard approach of using the septal collaterals to connect with the posterior descendent
artery is not available.
