Rotational
Atherectomy |
|
|
| |
Description |
|
| |
Some coronary artery
blockages are very calcified and resistant to routine
strategies, such as balloon angioplasty. Rotational
atherectomy is very useful in these situations. A tiny olive-shaped burr partially coated with diamond particles is used to “drill” through the blockage in the artery, typically spinning between 160-180,000 rpm. Typically the vessel is then treated
with balloon angioplasty and stenting. |
