"Clothespin" Like Clip Insertion to Repair Faulty Mitral Heart Valve
In the procedure which does not involve any surgery on the heart valve, doctors mounted a tool called a MitraClip on the end of a catheter and threaded it through the femoral vein in the groin into the heart, according to the study presented here at 59th annual conference of the American College of Cardiology.
A needle puncture in the wall separating the upper chambers of the heart enables the catheter to pass into the left atrium where the clip is opened up like a clothespin, said researchers.
Then, it is passed through the mitral valve into the left ventricle.
When the heart contracts, the flaps of the mitral valve fall into the clip, which then closes, pinning the flaps back together again, according to the report.
This technique enables the valve to close more effectively during contraction of the heart rather than allowing leakage of blood backward into the left atrium, the study said.
"As clinicians, we have seen our patients transformed from highly symptomatic to highly functional with a catheter procedure and without a long hospital stay or a long recovery," noted Doctor Ted Feldman, director of the cardio catheterization laboratory for North Shore University health system.
The MitraClip procedure helped 72.4 percent of those who received it, compared to a 87.8 percent success rate for surgery.
"The real excitement is seeing our experience with individual patients reflected in trial results in a clear way," he said.

How does one go about getting on the list for a MitraClip? I have severe regurgitation but because of previous bypass surgery I am not a good candidate for open heart surgery. I am 81 years old. Please let me know how apply for this procedure.

My grandfather is having this procedure tomorrow morning. It might prolong his life from 3-6 months to 2 to 5 good quaility of life years. His cardiologist is Dr. Colhmia in Tahlequah Oklahoma.
