Angioplasties including Rotablation
Rotablation is a process to remove calcified and solid blockage in the arteries. The calcified blockages are not easy to remove exclusively through angioplasty. In that case, a rotablator (or a small drill) is used to drill through the calcified blockage of arteries.
It is recommended by doctors in case the blocked arteries may not respond to angioplasty, a procedure where a tiny balloon at the end of a catheter is inserted into the artery to push aside the blockage. If the plaque is too hard and calcified, the process of rotablation is recommended. A rotablator is a drill with a diamond-coated burr on the end that fits into an artery and drills through the plaque. Without damaging the artery walls, it grinds the plaque into tiny pieces and lets it get washed away by the bloodstream. The body then processes and eliminates the plaque, leaving blood to flow again and supply the necessary nutrients and oxygen to the heart.
The procedure is done under local anaesthesia where the patient is awake and aware of the procedure. The catheter is usually inserted through groin or wrist area where the anaesthesia is given. It is a painless procedure.
