Opsens Inc. (TSX: OPS) (OTCQX: OPSSF)  announced today that it has obtained approval from Health Canada to market its dPR Proprietary Resting Index,  which measures intracoronary pressure and establishes a diagnosis with the heart at rest to guide the treatment of patients with coronary heart disease. dPR stands for Diastolic Pressure Ratio.

The measurement of Fractional Flow Reserve as a method of assessing intracoronary pressure is now the gold standard among medical professionals and has gained credibility and popularity following the publication of clinical studies demonstrating better clinical outcomes. This measurement is taken in the context where the heart is stimulated. Opsens’ dPR has been developed to meet the demand by cardiologists for a way to measure intracoronary pressure with the heart at rest.

Medical publications have highlighted the equivalence of several algorithms using the measurement of pressure at rest. These publications are expected to accelerate the adoption of resting pressure measurement indices in the interventional cardiology community.

“We are pleased to now be able to offer our diastolic pressure ratio to Canadian cardiologists, who have shown great support for our FFR products,” said Louis Laflamme, President and CEO of Opsens. “Accuracy of the pressure measurement becomes even more critical when pressure is measured with the heart at rest. The OptoWire is designed to provide the lowest drift in the industry. Now, combined with our resting index, it stands out for its accuracy and ease of use,” added Mr. Laflamme.

“The approval of Opsens’ dPR is a milestone, as it provides us access to a new growing segment of the market. dPR is now authorized for sale in Canada and Japan and is under review with regulatory agencies in the United States and Europe,” concluded Mr. Laflamme.
