ATS Medical Open Pivot(R) Heart Valve Featured in 11 Year Comparative Study

MINNEAPOLIS, April 9 (HSMN NewsFeed) -- ATS Medical, Inc. (Nasdaq: ATSI ) today noted that longer term clinical performance of the ATS Medical Open PivotŪ Heart Valve was profiled in a comparative scientific paper entitled "Single-Center Outcome Analysis of 1,161 Patients with St. Jude Medical and ATS Open Pivot Mechanical Heart Valves". The paper was published in the Journal of Heart Valve Disease, the official journal of The Society for Heart Valve Disease http://www.icr-heart.com/journal/ with Franziska H. Bernet, M.D. of Basel, Switzerland, as lead author.

Dr. Bernet and her colleagues reviewed and compared their experience with 601 ATS Medical Open Pivot Heart Valves (ATS) and 604 St. Jude Medical (SJM) valves implanted beginning in 1993. They reported similar overall survival and valve related mortality at 10 years for both patient cohorts even though there were considerably more ATS mitral valve replacements (168/67), where morbidity and mortality is expected to be higher. In the aortic group only, the authors reported significant improvement in actuarial survival at 10 years for those who received ATS (80%) compared to SJM (64%) leading them to conclude, "Based on the present results, it can be assumed that ATS valves would yield a better outcome in the aortic position." In the mitral position, actuarial survival at 5 years for ATS (80%) showed a significant improvement when compared to SJM (74%).

Michael Dale, President and CEO of ATS noted, "Our Open Pivot heart valve incorporates evolutionary design concepts with the intent of improving patient care and quality of life. Long term data, particularly well controlled comparisons such as this study from the University of Basel, are important contributions that can help us delineate the benefits of our valve and carry that message to surgeons and patients."
