The fistula between the proximal of RCA and SVC
They had some choices
1 Open the fistula, and close the entry and exit through the fistula ( or through the SVC). No need bypass.
2 Close the proximal RCA and the exit through the fistula ( or through the SVC). need bypass.
They chose 2. Why? I am afraid that SVG long term patancy. maybe too close.
