Dr. Jin’s presentation scheduled for 10:30 AM on Wednesday, May 2 is entitled “Implantation Technique and Implication of 3f Stentless Valve Design for Aortic Root Geometry.” It will open with a video of the implant procedure as performed by Mr. Ravi Pillai, MD, FRCS. Dr. Jin will follow with a review of the clinical follow up supporting his observations that the ATS 3f Aortic Bioprosthesis is the only valve replacement that fully preserves native aortic root geometry. Further, he will elaborate on how this may be crucial to enhanced long term durability and improved clinical performance.

Michael Dale, President and CEO of ATS noted, “By design, the ATS 3f Aortic Bioprosthesis is intended to provide a more natural and durable solution to the treatment of aortic valve disease by maintaining the continuity and integrity of the aortic root. Based on extensive clinical experience with the 3f valve, Dr. Jin and his colleagues have been able to provide surgeons and patients novel clinical evidence lending confirmation of the unique benefits of the patented 3f tubular valve design. Based on this clinical evidence and other pending reports we believe 3f represents a rewarding growth opportunity for ATS and a better clinical solution for patients.”

The highly regarded ACTS 2007 gathering on May 2 and 3 will focus on the latest surgical and interventional therapies for heart valve and coronary artery diseases, chronic atrial fibrillation and diseases of the aorta. The meeting will be held at The Equitable Center & Sheraton New York Hotel and Towers. The agenda and meeting details are available at http://www.promedicacme.com/conf_acts2007.htm.
