St. Jude Medical Reports 1st Use of Its PressureWire Aeris Technology

St. Jude Medical, Inc. has announced the first use of the PressureWire Aeris technology, an interventional tool which measures Fractional Flow Reserve (FFR) to evaluate the severity of blood flow blockages in the arteries.

In a release, the Company noted that this first-to-market technology helps interventional cardiologists better determine the ideal treatment option for their patients during coronary interventions, such as stent procedures. The first procedures in the U.S. were performed by Dr. Mark Zolnick at CHRISTUS St. Vincent Regional Medical Center in Santa Fe, New Mexico.

The PressureWire Aeris is a first-of-its-kind wireless FFR system which requires no additional equipment or cabling in the cardiac catheterization laboratory. Using the PressureWire Aeris technology, interventional cardiologists can accurately assess the severity of lesions. Having this information available prior to placement of coronary stents helps physicians better determine which specific lesion or lesions are responsible for a patient's ischemia, a deficiency of blood supply to the heart caused by blood restriction.

"Using the PressureWire Aeris helped me determine instantly and with certainty the best course of treatment for my patients. In the first case, I was able to decide that the narrowing of the arteries wasn't severe enough to warrant stenting, and in the next I used the FFR technology to confirm the ideal stent placement," said Dr. Mark Zolnick, a cardiologist at New Mexico Heart Institute. "The PressureWire Aeris is extremely easy to use, reduces material costs and improves patient outcomes. From both a clinical and cost effectiveness perspective, I believe that this technology should be a standard of care."

The Company said that the FAME trial, which compared FFR-guided treatment using St. Jude Medical PressureWire technology to stenting with angiography alone, found that in addition to saving about 11 percent in unnecessary material cost, instances of major adverse cardiovascular events, such as death, myocardial infarction and repeat revascularization, are reduced by 28 percent. The study also found that routine measurement of FFR requires no additional procedure time.

"St. Jude Medical is focused on providing physicians with technologies that aid them in making the best treatment decisions for their patients," said Frank Callaghan, president of St. Jude Medical's Cardiovascular Division. "PressureWire Aeris guides physicians to more accurately diagnose and treat their patients, significantly improving patient outcomes. Procedural set-up and workflow are also now improved, and having FFR measurements immediately accessible on existing cath lab instrumentation allows for quicker integration with patient records and a lower barrier to entry for the hospital to implement this patient-benefiting technology."
