What is coronary atherectomy?
Overview. DCA, or directional coronary atherectomy is a minimally invasive procedure to remove blockage from coronary arteries to improve blood flow to the heart muscle and ease pain. First, a local anesthesia numbs the groin area. Then the doctor puts a needle into the femoral artery, the artery that runs down the leg …
What are the risks with rotablation in the heart?
Acute no flow, severe vessel dissection with impending acute closure, atheroembolism and transient profound hypotension are the most frequently encountered risks in rotablation.
What is heart rotablation?
What is Rotablation? Rotational Atherectomy is a therapy performed with a small rotating cutting blade which is used to open a blocked artery and revamp the flow of blood to or from the heart. Often a stent (a tiny tube composed of metal mesh) is inserted in the artery to keep it from re-narrowing.
How much does atherectomy cost?
The mean cost of angioplasty was $7,301 +/- $4,637 and of atherectomy devices $9,345 +/- $8,856 (28% increase). The difference was principally related to an increase in cost of supplies: angioplasty $2,028 +/- $1,196 versus atherectomy $3,632 +/- $1,525 (79% increase).
How does rotablation work?
With rotablation, a special catheter, with an acorn-shaped, diamond-coated tip, is guided to the point of the narrowing in your coronary artery. The tip spins at a high speed and grinds away the plaque on your artery walls. The microscopic particles are washed away in your bloodstream.
Who invented rotablator?
The commercially available Rotablator (Boston Scientific, Natick, Massachusetts), invented by Auth and described by Ritchie and colleagues (4), ablates plaque using a diamond-encrusted elliptical burr, rotated at high speeds (140,000 to 180,000 rpm) by a helical driveshaft, that advances gradually across a lesion over …
