Major New Study Shows Aortic Valve Replacement Via Catheter Produces Better Outcomes Than Traditional Open-Heart Surgery
Date:4/3/2011

first cardiac physician in the world to design a method for delivering synthetic valves to the heart via the groin artery.  "The results of the randomized, multi-center trial show conclusively that implanting new aortic valves through catheter tubes is much easier on patients than subjecting them to the pain, trauma and infection-risk that accompanies open-heart surgery."

Only about a month ago, a multidisciplinary team of DMC physicians, nurses, research teams and technologists made headlines by achieving two aortic valve implants.  Using a new "Medtronic CoreValve" device expressly designed for that purpose, Dr. Schreiber and Dr. Ali Kafi, chief of clinical cardio-thoracic surgery at DMC Harper University Hospital, performed the breakthrough procedure with two heart patients in late February.

The two CVI patients who received the new aortic valves are among more than 300,000 people worldwide (100,000 in the U.S.) now struggling with aortic valve stenosis.  That often-disabling condition, usually caused by narrowing of the valve and resulting restriction of blood flow from the heart to the body, typically develops by age 50-70 and progresses with advancing age.

Until the recent development of the TAVI system, however, the only therapeutic alternative for patients with stenosis was open-heart surgery.

Dr. Schreiber, who was also a pioneer in developing the stent procedure for relieving blocked carotid arteries, said that the results of the just-released ACC study, organized and administered by a team of interventional cardiologists and cardiac surgeons at Columbia University, provides "powerful scientific evidence that non-invasive catheterization is superior to open-heart surgery among older patients."  

Physicians are available for interviews.
