Diamondback 360® Coronary Orbital Atherectomy System (OAS)

Blocked Coronary Arteries

Coronary artery disease (CAD), the most common type of heart disease, and the leading cause of death in the United States in both men and women, is a narrowing of the vessels that supply blood and oxygen to the heart. Commonly treated with angioplasty, a small balloon is connected to a catheter, guided through the artery, and inflated to make room for a metal stent that keeps the artery open.

However, more than 40 percent of patients with CAD have calcified coronary lesions, caused by a buildup of calcium plaque from hardened cholesterol. When arterial walls become lined with rough calcified plaque, the blood flow paths may become irregular, and decrease the ability for a cardiologist to expand a balloon in order to insert a stent. These high risk patients do not respond to conventional methods. In these cases, the hardened plaque buildup must be modified for stent placement. Until now, the only tools available for breaking down the plaque were aggressive, often times required multiple procedures, and put patients at a potentially higher risk.

First in Area to Perform Less-Invasive Procedure

Premier Health is proud to be associated with the first major advancement in 25 years specifically designed to remove calcified coronary lesions. As part of Premier Health’s initiative to provide advanced technology and better clinical outcomes for treatment of patients with coronary artery disease, C. David Joffe, MD, FACC, primary site investigator, along with Gary Fishbein, MD, FACC, and Amit Goyal, MD, FACC, were the only physicians in Ohio to participate and enroll patients in the two-year clinical trial for a new tool, the Diamondback 360® Coronary Orbital Atherectomy System (OAS). In September 2014, Dr. Joffe performed the first orbital atherectomy.

Premier Health physicians contributed a significant number of cases to the pivotal ORBIT II trialOff Site Icon, and are excited to have been a contributing factor in FDA approval. The Diamondback 360® OAS is the only FDA device approved for treatment of severely calcified coronary lesions, and is subsequently approved by Medicare for reimbursement for patients who qualify for such treatment.

Coronary Atherectomy - Spinning in a New Direction

Safer and more effective than traditional methods for most patients, the Diamondback 360® orbital system prepares the vessel for the balloon and stent by placing a thin wire with a diamond-coated crown into the artery. The crown spins with variable speeds, gently sanding down plaque into tiny particles that the body is then able to absorb – eliminating the need for additional procedures to treat and remove large chunks of broken-up plaque. The centrifugal force of the orbital spin allows for continuous blood flow, and for the crown to nudge the walls of the artery, more effectively clearing the artery of blockages, and restoring flexibility – allowing for a lower risk/lower pressure
