CSI’s Diamondback 360 Coronary Orbital Atherectomy System Introduced in Canada

August 30, 2021—Cardiovascular Systems, Inc. (CSI) announced the introduction in Canada of its Diamondback 360 coronary orbital atherectomy system (OAS).

The first patients in Canada were treated by Sanjog Kalra, MD, who is an interventional cardiologist and cardiac critical care physician at the Peter Munk Cardiac Center, Toronto General Hospital, part of the University Health Network, in Toronto, Canada.

“Patients with calcific coronary artery disease can have poor clinical outcomes unless optimally treated,” commented Dr. Kalra in CSI’s press release. “Revascularization for these patients requires interventionalists to fully prepare vessels for stenting so that full stent expansion is achieved. We know that perfect stent results lead to the best outcomes.

“Achieving optimal vessel preparation in heavily calcified coronary arteries is amongst my most challenging procedures. CSI’s orbital atherectomy technology enables effective calcium modification to facilitate full stent expansion. In addition, OAS is optimized for efficiency as it allows bidirectional atherectomy in multiple vessel sizes with one device.”

According to the company, the Diamondback device combines sanding and pulsatile force to treat a broad range of calcium morphology and lesion types. Additionally, orbital atherectomy has demonstrated clinical advantages compared to alternative treatments, including low rates of procedural complications and target lesion revascularization through 3 years.

CSI’s ORBIT II and COAST clinical studies demonstrated that OAS is safe and effective in treating patients with de novo severely calcified coronary lesions. Two real-world studies with approximately 1,000 patients have reinforced Diamondback’s safety and high procedural success, stated the company.
