Rotablation uses a tiny drill with a small rotating cutting blade which is used to open a blocked artery and revamp the flow of blood to or from the heart.
Often a stent is inserted in the artery to keep it from re-narrowing.
It has a diamond-tipped burr, powered by compressed air to break up calcified plaque (hard block) that is clogging the coronary artery.
The tip spins at a high speed and grinds away the plaque in artery walls, microscopic particles are washed away in bloodstream.
Once this has been done, a balloon can be inserted, and the angioplasty can proceed as normal.
