Quebec first at the ICM to cleanse the calcium that blocks the arteries


The orbital atherectomy system literally sprays calcium into the arteries, allowing the interventional cardiologist to then install a stent (stent) which keeps the artery open and helps the blood flow properly.

Calcium becomes very, very small sand downright, summarized Dr. Guillaume Marquis-Gravel, who is one of the four doctors qualified to perform this intervention in Canada and the only one in Quebec. We can put the tutor at this time more easily.

The device rotates at the impressive speed of 80,000 to 120,000 revolutions per minute. Not only does it break down the calcium that has accumulated along the artery walls, but the vibrations it generates will also fracture the calcium that has deposited outside the arteries, allowing the cardiologist to install its endoprosthesis even more easily.

Compared to rotational atherectomy which was heretofore used to attack calcium deposits in arteries, orbital atherectomy is much easier to use and the risk of complications is lower., said Dr Marquis-Gravel, who was accredited during his fellowship in Interventional Cardiology at Duke University.

There is less risk of puncturing the artery, ending up with devices that get stuck in the arteries of the heart, he said. Then at the same time [l’appareil] attacks a greater diversity of calcification.

If all goes well, the patient is discharged the same day as the operation.

Coronary artery disease affects the arteries that supply the heart with blood and oxygen. This condition creates a blockage of one or more of these arteries, which can then lead to health problems such as angina attacks or myocardial infarctions.

The most common cause of these blockages is the build-up of plaques made up of substances like calcium or cholesterol. Coronary artery disease cannot be cured, but it can be treated with medication, lifestyle changes and, in more severe cases, percutaneous or surgical procedures.
