New diagnostic system offers advanced insight into patient’s arteries to improve diagnosis and treatment of coronary artery disease
San Jose, September 12, 2012 – Regional Medical Center of San Jose is the first non-academic hospital in Northern California to offer St. Jude Medical’s ILUMIEN™ PCI Optimization System as a treatment option for patients suffering from coronary artery disease (CAD). The ILUMIEN system is the first and only integrated diagnostic technology that combines optical coherence tomography (OCT) and fractional flow reserve (FFR) technologies on one platform.
FFR technology is used when a patient has symptoms that suggest a narrowing of an artery due to plaque or cholesterol build up. A very thin wire is inserted into a small guiding catheter into a narrowed artery during a heart procedure. A sensor on the wire measures blood pressure before and after the narrowing. This reading indicates to physicians which arteries are not properly delivering oxygen to the heart.
The OCT system utilizes near-infrared light to create images to visualize and measure important vessel characteristics otherwise not visible or difficult to assess with older intracoronary imaging technologies- such as fluoroscopy and intravascular ultrasound (IVUS). The OCT technology is also used to visualize and measure important vessel characteristics that are used in guiding stent selection and deployment, and also provide post-stenting information to help ensure the procedure was successful Using the combined ILUMIEN system, physicians at Regional gain advanced physiological and anatomical insights that can improve the diagnosis and treatment of heart disease.
Shahid Siddiqui, M.D., Medical Director of Regional’s Cath Lab was the first to use the ILUMIEN system at the hospital. "The key to optimizing treatment of coronary artery disease is knowing which blockage needs treatment and how to treat it," said Dr. Siddiqui. "The ILUMIEN system allows me to have the information I need in one place and helps me accurately diagnose and optimize therapy for my patients." With the integration of these two technologies, Regional physicians can identify the precise measurement and dimensions of culprit narrowings responsible for obstructing blood flow to a patient's heart, as well as determine vessel size and structure. The ILUMIEN™ PCI Optimization System received U.S. Food and Drug Administration (FDA) and European CE Mark approval in 2011.

About Fractional Flow Reserve (FFR)
Fractional Flow Reserve (FFR) is a measurement that helps physicians identify which coronary artery narrowings are obstructing blood flow to the patient’s heart muscle (called ischemia) and are in danger of causing a coronary artery event, such as a heart attack. Current data show the readings generated by FFR prior to the placement of a coronary stent helps physicians better optimize clinical outcomes by determining which specific lesion or lesions are responsible for a patient's ischemia. In January 2009, St. Jude Medical announced results from the landmark FAME (Fractional Flow Reserve (FFR) vs. Angiography in Multivessel Evaluation) study, a randomized, prospective, multi-center study. The study enrolled 1,005 patients with multivessel coronary artery disease and compared outcomes for patients whose treatment was guided by FFR to those whose treatment was guided only by angiography. The 12-month results, published in the January 15, 2009 issue of the New England Journal of Medicine, demonstrated that instances of major adverse cardiovascular events (MACE), including death, myocardial infarction or repeat revascularization, were reduced by 28 percent for patients whose treatment was guided by FFR rather than by standard angiography alone. After two years, patients who received FFR-guided treatment continued to experience improved outcomes over time, including a 34 percent risk reduction in death or heart attack.
