Rotablator Rotational Atherectomy

Blockages in the coronary arteries can cause symptoms such as chest pain and breathlessness and can increase heart attack risk. Sometimes part of the process in forming the blockage involves calcium being deposited in the arterial wall. Calcium is rigid (like bone) and can prevent successful treatment with standard techniques such as coronary stenting.

Rotablator treatment involves passing a small device into the coronary artery via a catheter introduced via the wrist or groin. The Rotablator rotates at very high speed (180 000 rpm) and can remove calcification from the arterial wall. Following this the artery is usually treated with a stent.
