What is it?
Rotablation uses a small elliptical diamond-coated burr spinning at very high speed to pulverise calcified plaque into microscopic particles that are cleared naturally by the circulation.
Who needs it?
Severely calcified lesions that a balloon — or even a microcatheter — cannot cross or expand.
How is it done?
After a dedicated RotaWire is passed, the burr is advanced at about 140,000–180,000 rpm with short, gentle passes. Further lesion preparation and stenting follow.
Before the procedure
Careful assessment of heart and kidney function; mechanical support may be planned in high-risk cases.
After & recovery
Usually one night of monitoring in the coronary care unit, then recovery as for angioplasty.
Risks & safety
Performed by an experienced team. Slow/no-reflow, perforation or burr entrapment are rare but important and minimised by correct technique.
Frequently asked questions
Rotablation vs IVL?
Rotablation debulks plaque and is essential for uncrossable lesions; IVL cracks calcium in place. Sometimes both are combined (“RotaTripsy”).
Do I need general anaesthesia?
No; local anaesthesia and sedation are usually enough.
