  WEST CHESTER, Ohio--(BUSINESS        WIRE)--November 03, 2014--
  AtriCure, Inc. (Nasdaq: ATRC), a        leading innovator in surgical treatments for atrial fibrillation (Afib)        and left atrial appendage management (LAAM), today announced it has        received approval for an Investigational Device Exemption from the U.S.        Food and Drug Administration (FDA) to begin enrollment in the Dual        Epicardial and Endocardial Procedure (DEEP) clinical trial. The DEEP        trial is a prospective, multicenter, single arm, pivotal study to        evaluate patients with persistent or long-standing persistent atrial        fibrillation. This is the first pivotal study of its kind in the United        States.
  The study is designed to evaluate the safety and efficacy        of the DEEP approach in treating non-paroxysmal (also called persistent,        long-standing persistent and permanent) atrial fibrillation. The DEEP        approach utilizes the specialized skills of both the cardiac surgeon and        electrophysiologist (EP) to treat more severe cases of Afib, such as        non-paroxysmal, which historically have been the most difficult to treat.
  In        the DEEP study, the cardiac surgeon and EP work as a team to perform a        minimally invasive epicardial (outside the heart) ablation and        endocardial (inside the heart) catheter-based ablation. The primary        effectiveness endpoint is freedom from Afib and freedom of Class I or        III antiarrhythmic drug therapy. AtriCure has FDA approval to enroll 220        subjects at up to 25 sites in the U. S. and internationally.
  "We        are pleased to be moving into this next phase of a pivotal trial for        DEEP," said Mike Carrel, chief executive officer of AtriCure. "Our goal        is to start the Institutional Review Board process with many of the        leading institutions right away. We intend to have our first subject        enrolled in early 2015, with completion of enrollment targeted for        mid-2017."
  "AtriCure is embarking on this landmark trial        which will bring electrophysiologists and cardiac surgeons together as a        team in an effort to establish a new standard of care for patients        presenting with persistent or long-standing persistent Afib, a        significant risk factor for stroke," said Dr. James L. Cox, Emeritus        Evarts A. Graham Professor of Surgery at Washington University.        "AtriCure is fortunate to have such a distinguished group of physicians        to provide leadership for this important trial."
  The        principal investigators for DEEP are Dr. Kenneth Ellenbogen, Chairman of        the Division of Cardiology at Virginia Commonwealth University (VCU)        Pauley Heart Center; Dr. Paul Wang, Director, Stanford Arrhythmia        Service, Professor of Medicine and Bioengineering, by courtesy, Stanford        University School of Medicine; Dr. Vigneshwar Kasirajan, Chairman,        Department of Surgery and Division of Cardiothoracic Surgery and        Professor, Department of Surgery at VCU Pauley Heart Center; and Dr. Ali        Khoynezhad, Professor of Cardiovascular Surgery at Cedars-Sinai Heart        Institute.
  "We look forward to pioneering the multi-specialty        approach where EPs will work more closely with cardiac surgeons in this        dual surgical approach," said Dr. Ellenbogen.
  "I think the        combined surgical-catheter ablation approach is a promising treatment        for atrial fibrillation," said Dr. Wang. "That's why I'm really excited        about being involved with this important study."
  Atrial        fibrillation is the most common type of arrhythmia and can cause blood        clots, stroke, heart failure and other heart--related complications. A        patient with Afib has a high risk of stroke because the irregular        heartbeat allows blood to pool in the left atrial appendage (LAA) and        form clots that can travel through the body and into the brain.
  Atrial        fibrillation patients who have failed antiarrhythmic drug therapy and        received up to two failed catheter ablations are candidates for the DEEP        study, which is performed in two phases. In the first phase, the surgeon        will make small incisions to perform endoscopic epicardial ablation        using the AtriCure Bipolar System, and occlude the LAA with the        AtriClip(R) LAA Exclusion System. Then about three months later, the        patient will undergo an endocardial mapping and catheter ablation        procedure performed by the EP.
  "The DEEP procedure combines the        expertise of both the EP and cardiac surgeon and seeks to set a new        standard of care for Afib ablation therapy," said Dr. Kasirajan.
  "The        DEEP procedure is an integrated and minimally-invasive approach to        resistant atrial fibrillation combining the strengths of multi-specialty        ablation techniques. I am excited about the DEEP trial and evaluating        patients with non-paroxysmal Afib for whom the outcome of traditional        endocardial ablation has been challenging," said Dr. Khoynezhad.
  More        than 2.7 million Americans are living with Afib, a cardiac rhythm        disorder that increases in prevalence with age. Afib is associated with        a five-fold increased risk of stroke. It is responsible for nearly        100,000 deaths, and adds $26 billion in expense to the U.S. healthcare        system, each year. (1)
