What many don’t realize is that our arteries can function well even if some blockage exists. It comes down to how well the blood is flowing in vessels. During the cath procedure, pressure differential is measured across a blockage to determine its severity. Not every blockage needs a stent nor does every vessel have the same significance. A 80% blockage in a proximal, large caliber artery is NOT the same as one in a distal, small caliber branch.

I’m in awe of what doctors can achieve with this procedure and the countless lives it has saved.
