The primary treatment focus of an atherectomy procedure is to remove blockages in arteries. This minimally invasive surgical technique is specifically designed to clear out plaque buildup from the inner walls of arteries. Plaque can consist of cholesterol, fatty substances, and other cellular debris that can narrow or obstruct blood vessels, leading to issues such as coronary artery disease.

By performing atherectomy, physicians aim to restore proper blood flow through the arteries, thereby reducing the risk of heart attacks or other cardiovascular complications associated with blockages. The procedure involves the use of specialized devices that can shave or grind away the plaque without requiring large incisions, making it an effective option for patients with significant arterial blockages.

The other treatment focuses, such as restoring valve function, increasing oxygen in the blood, or repairing heart defects, do not align with the primary goal of atherectomy, which is specifically targeted at addressing blockages caused by atherosclerosis.
