My right artery from my heart has a blockage and they have to back for a roto rooter procedure. Could not unblock all of it the first time. Complicat?

More complex . A rotoblator procedure is more complex than a cardiac stent. It means that there is significant calcification of the artery that cannot be stented by conventional means. If all goes well, it is a same day procedure and you will typically leave home the next day. It has a higher complication rate however.
