Novel post-processing image for the visualization of the coronary sinus by multidetector-row computed tomography before cardiac resynchronization therapy: edge-enhanced image.
BACKGROUND
Before performing cardiac resynchronization therapy (CRT), it is useful to visualize the position of the coronary sinus (CS) orifice where the CS lead is inserted.


RESULTS
A raysum image was created in which the outermost 1-voxel layer of the right atrium (RA) and CS was extracted. This image enabled visualization of the positional relationship between the RA and CS ostium using the same geometry as retrograde CS venography.


CONCLUSIONS
New post-processing imaging of the CS orifice will make the procedure of CRT safer.
