#EPEEPS Fun CRT case yesterday, posted with patient’s permission. ccTGA, dextroversion, 2:1 AV block, (ECG with right sided leads). Pre-procedure planning with imaging imperative for congenital patients. MRI and 3D printing of heart. /1 
Did a levophase coronary angio from left main but not very helpful. /2
Target vessel could be seen with an RCA injection instead.
Here's a still of the vessel. /4
Very challenging to get into vein since the annulus moved so much, but accessed CS with an AL2 and glidewire. /5
Final result here, with paced ECG.
