MitraClip for Mitral Regurgitation
Mitral regurgitation impacts millions of adults in the United States and if left untreated, can be life-threatening.
The mitral valve, located between the left atrium and the left ventricle of the heart, is responsible for regulating the flow of oxygen-rich blood received from the lungs. Proper one-way flow of blood through the mitral valve is made possible by the two leaflets (flap-like structures) of the mitral valve.
Mitral regurgitation occurs when the mitral valve leaflets do not close completely and blood flows backward or “leaks,” creating symptoms that may include shortness of breath, fatigue and chest pain.
When severe, mitral regurgitation is often treated with open-heart valve surgery. However for high-risk patients, open-heart surgery may not be the best treatment option. For these patients, MitraClip is the only approved minimally invasive, non-surgical treatment option.
During a MitraClip procedure, the MitraClip device is inserted in to the body through a catheter placed in the patient’s femoral (leg) vein. The catheter is then threaded up the vein to the heart. Once in the heart, a small hole is made in an internal wall of the heart (the atrial septum) and the MitraClip device is advanced across the mitral valve. The device is positioned and placed to join or “clip” together a portion of the mitral valve leaflets, reducing or eliminating the backward flow of blood.
Unlike open-heart valve surgery, during the MitraClip procedure there is no need for a heart-lung bypass machine. The minimally invasive, transcatheter approach allows patients to recover faster and experience an improvement in symptoms soon after the procedure.
Northwestern Memorial is heavily involved in the use of MitraClip technology through ongoing work led by Mark J. Ricciardi, MD and team of dedicated physicians, which includes cardiologists Charles J. Davidson, MD, and Jyothy J. Puthumana, MD, and cardiac surgeon S. Chris Malaisrie, MD.
