Guidant Announces European Approval of Next Generation Cardiac Resynchronization Therapy Defibrillator.INDIANAPOLIS, Ind. & ST. PAUL, Minn. -- Guidant Corporation (NYSE NYSE See: New York Stock Exchange :GDT GDT Global Descriptor Table GDT Geographic Data Technology Inc. GDT Gas Discharge Tube (energy, electrotechinical and electronics) GDT Getting Things Done GDT Geometric Dimensioning & Tolerancing GDT Ground Data Terminal ) Innovative System Combines Treatments for Heart Failure, Atrial Arrhythmias and Sudden Cardiac Death Sudden Cardiac Death Definition Sudden cardiac death (SCD) is an unexpected death due to heart problems, which occurs within one hour from the start of any cardiac-related symptoms. SCD is sometimes called cardiac arrest. Guidant Corporation (NYSE:GDT) today announced Conformite Europeenne (CE) Mark approval and first implant of its CONTAK RENEWAL(R) 4 AVT AVT avian arginine vasotocin. See vasotocin. cardiac resynchronization therapy defibrillator defibrillator, device that delivers an electrical shock to the heart in order to stop certain forms of rapid heart rhythm disturbances (arrhythmias). The shock changes a fibrillation to an organized rhythm or changes a very rapid and ineffective cardiac rhythm to a . The system is designed to treat heart failure patients who are at risk for sudden cardiac death and also suffer from atrial arrhythmias. Atrial arrhythmias affect approximately half of the 6.5 million Europeans and 5 million Americans who suffer from heart failure. Guidant will launch the CONTAK RENEWAL 4 AVT system in Europe later this quarter. "Not only is atrial fibrillation atrial fibrillation Irregular rhythm (arrhythmia) of contraction of the atria (upper heart chambers). The most common major arrhythmia, it may result as a consequence of increased fibrous tissue in the aging heart, of heart disease, or in association with severe infection. one of the more important co-morbidities in heart failure, it is also difficult to treat," said Johannes Sperzel, M.D., at Kerckhoff-Klinik, Bad Nauheim, Germany, where the first implant was performed earlier this month. "The availability of a cardiac resynchronization therapy defibrillator that can also diagnose and treat an atrial arrhythmia has enormous potential for millions of heart failure patients worldwide because it enables physicians to treat both the upper and lower chambers of the heart." "The RENEWAL 4 AVT is a tangible example of our capability to deliver meaningful product innovation," said Fred McCoy, president, Cardiac Rhythm Management Cardiac rhythm management is a field of treatment in cardiology. The purpose is managing cardiac rhythm disorders. Usually it involves artificial pacemakers and/or implantable cardioverter-defibrillator therapy as well as antiarrhythmia drugs. , Guidant Corporation. "We are pleased to provide this new treatment option to our physician customers for the patients they serve." The CONTAK RENEWAL 4 AVT system is designed to determine the origin of an irregular heartbeat and provide the appropriate therapy. Once the origin and severity of the arrhythmia arrhythmia (ārĭth`mēə), disturbance in the rate or rhythm of the heartbeat. Various arrhythmias can be symptoms of serious heart disorders; however, they are usually of no medical significance except in the presence of is determined, the device provides either pacing therapy or delivers an appropriate shock to return the heart to a normal rhythm. The RENEWAL 4 AVT system's diagnostic tools also assist physicians in accurately diagnosing a patient's condition, documenting symptoms, gaining clear insight into disease progression and monitoring the effectiveness of the therapy. About Atrial Arrhythmias Atrial arrhythmias are irregular beats that begin in the heart's upper chamber. Normally, the electrical signal that tells your heart to beat comes from the sinoatrial node, or SA node, in the right atrium. But during atrial fibrillation, signals start irregularly from several areas in the atria Atria The heart has four chambers. The right and left atria are at the top of the heart and receive returning blood from the veins. The right and left ventricles are at the bottom of the heart and act as the body's main pumps. . These disorganized dis·or·gan·ize tr.v. dis·or·gan·ized, dis·or·gan·iz·ing, dis·or·gan·iz·es To destroy the organization, systematic arrangement, or unity of. electrical signals cause the atria to quiver rapidly and irregularly, instead of beating in a regular rhythm. Atrial fibrillation keeps the heart's upper and lower chambers from working together properly. This can decrease the heart's pumping efficiency by as much as 20 to 30 percent. Additionally, people with untreated atrial fibrillation may be at significantly greater risk for stroke than people with normal heart rhythms. Because blood does not flow through the atria smoothly, blood clots may form in the heart. If a blood clot is dislodged from the heart, it can travel to the brain and result in stroke.
