What are atherectomy devices?
Atherectomy devices were developed to permit drilling, grinding, or sanding of atheroma, calcium, and excess cellular material from the site of a coronary occlusion or stenosis. Both mechanical and laser-based approaches are used.
What is a rotablator procedure?
This is a procedure which attempts to “bore out” a narrowing in a coronary artery which might not otherwise respond to stenting. The test involves the insertion of a long thin catheter into an artery in the groin or wrist under local anaesthetic.
How safe is Rotablation?
53% of all patients had a re-study within 2 years. Of these, 5% had target vessel revascularisation (TVR), 10% had target lesion revascularisation and 22% had non-TVR. Conclusion: Rotablation is a relatively safe and successful procedure in a high risk group of patients.
What is rotablator atherectomy?
The Rotablator Atherectomy System is an air-driven system featuring a 5-micron diamond-tipped burr that rotates at up to 190,000 RPM.
What is the difference between angioplasty and atherectomy?
Angioplasty — A balloon is inflated to open the vessel. Angioplasty and stent placement — After the balloon is used, a mesh frame called a stent will be placed in the vessel to support the walls. Atherectomy — The plaque is removed using a rotating shaver or laser.
How does laser atherectomy work?
Peripheral laser atherectomy uses a catheter that emits high energy light (laser) to unblock the artery. The catheter is maneuvered through the vessel until it reaches the blockage. Laser energy is used to essentially vaporize the blockage inside the vessel. The result is increased blood flow to the peripheral tissue.
How long does an atherectomy take?
How long does the atherectomy procedure last? The procedure itself generally takes two hours, but the preparation and recovery time add several hours. Following the procedure, you will need to lie flat for three to six hours. The surgery may require a minimum hospital stay of one to two days.
What is a rotablator used for?
The rotablator is used in a type of catheter-based procedure called rotational atherectomy. Rotational atherectomy is a minimally invasive treatment that is sometimes used to pulverize hardened plaque within a coronary artery.
How does the rotablator rotational atherectomy system work?
When it comes to atherectomy, trust the Rotablator System for proven patient outcomes. The Rotablator Atherectomy System is an air-driven system featuring a 5-micron diamond-tipped burr that rotates at up to 190,000 RPM.
Can a rotational atherectomy be performed before Ra?
Direct intracoronary administration of vasodilators prior to system activation can be performed at this time to combat coronary spasm potentially instigated by RA.
Where does the Burr go during rotational atherectomy?
At the end of the initial RA pass, the burr is positioned in its starting position proximal to the lesion before the system is deactivated. The system should not be deactivated while the burr is contained within the lesion.
Can a rotational atherectomy be a debulking strategy?
The appearance of vessels undergoing rotational atherectomy as a debulking strategy has been described.32 In this study, 28 patients (22 calcified plaques, a third of which were circumferential) underwent ultrasound imaging after the procedure (with 71% having adjunct balloon angioplasty).
