HeartWare International Surpasses 50 Implants in the US

August 20, 2009

FRAMINGHAM, Mass. and SYDNEY, Aug. 20 /PRNewswire-FirstCall/ — HeartWare International, Inc. (Nasdaq: HTWR – ASX: HIN) today announced that HeartWare has surpassed 50 implants in the United States under its ADVANCE Clinical Trial, marking an important early enrollment milestone.

The 50th implant in the US was performed last week at the Texas Heart Institute in Houston, Texas by O.H. Frazier, MD a distinguished surgeon, scientist, and academician renowned for his research and development of new cardiovascular surgical techniques and ventricular assist devices. “We are very pleased with the early clinical results of this small pump. Its unique inflow cannula and small size enable us to place the device without a surgical pump pocket, which greatly reduces the risk of serious infection. The improved pump simplifies implantation and allows for optimal function, even in difficult cases where the myocardium is thin or the apex of the ventricle is difficult to access,” said Dr. Frazier.

HeartWare’s ADVANCE Clinical Trial is an FDA approved IDE study designed to evaluate the HeartWare((R))( )Ventricular Assist system as a bridge to heart transplantation for patients with end-stage heart failure. The primary endpoint of the trial is survival at 180-days post surgical implantation. Under the IDE, a total of 150 patients will be enrolled across a maximum of 28 centers. Currently, 16 centers are enrolling patients. HeartWare expects the number of active centers to expand steadily over coming months as the balance of the 28 sites work through the steps required to begin enrolling patients.

About End-Stage Heart Failure

Heart failure is one of the leading causes of death in the developed world. According to the American Heart Association, congestive heart failure (CHF) afflicts approximately 5 million people in the US with approximately 550,000 new cases diagnosed each year. Despite new treatment strategies for patients with end-stage heart failure, the number of patients who die with this disease is of epidemic proportion. Cardiac transplantation is currently the most effective therapy for the treatment of advanced end-stage heart failure, however, its application is limited due to the lack of available donor organs.

Over the last decade, bridging to cardiac transplantation with implantable left ventricular assist devices (LVADs) has gained wider clinical acceptance and LVADs are used to extend life expectancy for patients with end-stage heart failure who might otherwise deteriorate while awaiting a donor heart.

About HeartWare International

HeartWare International develops and manufactures miniaturized implantable heart pumps, or left ventricular assist devices, to treat Class IIIb and Class IV patients suffering from advanced heart failure. The HeartWare((R)) Ventricular Assist System features the HVAD((TM)) pump, a small full-output circulatory support device (up to 10L/min flow) designed to be implanted next to the heart, avoiding the abdominal surgery generally required to implant competing devices. HeartWare has received CE Marking for the HeartWare((R)) Ventricular Assist System in the European Union. The device is currently the subject of a 150-patient clinical trial in the United States for a Bridge-to-Transplant indication.

HeartWare International, Inc. is a member of the Russell 2000((R)) and its securities are publicly traded on The NASDAQ Stock Market and the Australian Securities Exchange.
