Rotablation (Rotational atherectomy)
Rotablation (Rotational atherectomy) is a complex and the most challenging technique in coronary intervention used in patients with heavy calcification in coronary arteries (hardened arteries) to deliver stents in position to improve blood flow. It is essentially a drilling technique done with the help of special diamond tip burr, which rotates at a speed of 150,000 to 200,000 rotations per minute. This drilling technique clears the inside of the arteries to help pass the balloon and stent easily. The tubes or catheters used in this technique are bigger than the normal catheter. This technique is used carefully only by very well trained Interventional cardiologist in special situations. Even though the procedure is slightly riskier, in trained hands the risks still remains low and in some situations, this is the only option available.
