EP MedSystems' Ultrasound Product Used in Heart Failure Treatment

WEST BERLIN, N.J.--(HSMN NewsFeed)--April 20, 2006--EP MedSystems, Inc. (NASDAQ: EPMD ), a market leader in electrophysiology products used in cardiac rhythm management, today announced that its ViewFlex(TM) ultrasound imaging catheter was used in a unique procedure to treat a patient in dysynchrony with heart failure. The procedure was performed by Sanjeev Saksena, MD, the Company's Senior Medical Advisor. Dr Saksena is practicing cardiac electrophysiology and Clinical Professor of Medicine at the Robert Wood Johnson School of Medicine in New Brunswick, New Jersey.

The procedure was successfully performed to resynchronize the left ventricle in a patient who previously had an implanted cardiac resynchronization pacemaker device, which had failed to improve heart function. Cardiac resynchronization therapy (CRT) is an innovative new therapy that can relieve heart failure symptoms by improving the coordination of the heart contractions. EP MedSystems' ViewMate® system provided visualization used in both optimizing the positioning of the pacemaker electrode and the programming of the device, allowing resynchronization as well as increased cardiac output. The patient's ejection fraction, the percentage of blood that is pumped out of a filled ventricle with each heartbeat, improved from 21% to 39%.

Dr Saksena stated, "The real time measurements from EP MedSystems' ViewFlex(TM) catheter allowed me to optimize the intended therapy of the implanted resynchronization device, thereby improving the patient's heart function. We see failed resynchronization therapy in 30-40% of patients implanted with these devices. I believe that utilization of this ultrasound technique during original implant procedures, could improve success rates significantly, benefiting the patients."

Studies have shown that cardiac resynchronization therapy can improve quality of life for heart failure patients by reducing symptoms like fatigue and shortness of breath. Heart failure is a condition that progressively weakens the heart and therefore loses its ability to pump an adequate supply of blood to the body. Approximately 5 million Americans suffer from heart failure, with approximately 550,000 new cases diagnosed each year. The economic burden of heart failure is estimated at $40 billion per year.

EP MedSystems' ViewMate® ultrasound system is a fully computerized instrument for the capture of intracardiac ultrasound images. It provides digital image acquisition and display of images from the ViewFlex(TM) intracardiac catheter inserted into the heart through intravascular access.

EP MedSystems will be sponsoring a symposium at the upcoming HRS meeting in Boston, MA. The symposium is entitled New Clinical Techniques and Imaging Technology in Interventional Electrophysiology. This symposium will focus on two areas of clinical importance; Atrial Fibrillation, as well as, New Directions in Interventional Electrophysiology. After the presentations, the Symposium will conclude with a panel discussion. The chairman for the symposium will be Dr. Bradley Knight, University of Chicago, Dr. Fred Kusumoto, Mayo Clinic, Dr. James Maloney, Carondelet Heart Institute and Dr. Steven A. Kutalek, Hahnemann University Hospital. The symposium will be held on Thursday May 18th, 2006 from 7:00 to 9:00PM at the Essex North/Center Ballroom in the Westin Copley Hotel.
