Transcatheter (otherwise know as percutaneous) procedures are performed in our state-of-the-art catheterization lab by a team of highly skilled interventional cardiologists. For patients with heart valve disease or congenital heart defects that are too high risk for traditional surgical procedures, catheterization offers an alternative treatment solutions that uses minimally invasive techniques to repair mitral valves, replace aortic valves, to seal leaks and more.
TAVR is a minimally invasive alternative for patients who are too high-risk for traditional aortic replacement surgery. Instead of opening the chest, a small tube (catheter) is guided through an artery in the groin or between the ribs into the heart. The artificial valve is compressed and fed through the catheter until it reaches the aortic valve. Once in place, a balloon expands the artificial valve and the catheter is removed. The new valve replaces the old, increasing blood flow throughout the body.
For patients with mitral valve regurgitation (leaky valve) who are too high-risk for traditional or robotic surgery, transcatheter mitral valve repair offers an alternative solution. During this minimally invasive procedure, a mechanical clasp, called the MitraClip, is implanted into the heart using a catheter that is guided to the chest through the femoral vein. The MitraClip clamps the mitral valve leaflets together, reducing leakage and associated symptoms of regurgitation.
Some heart failure patients that have a left ventricular assist device (LVAD) may develop aortic insufficiency that requires additional treatment. A transcatheter aortic valve fusion is a minimally invasive procedure used to treat stenosis for heart failure patients with circulatory support devices. The University of Chicago has extensive experience in treating these patients and has developed techniques to improve their quality of life.
The left atrial appendage (LAA) is a small pouch in the muscle wall of the left atrium. When a patient has atrial fibrillation, this pouch can collect blood that can form clots, creating an increased risk of stroke. To minimize this risk, our interventional cardiologists can seal the LAA through catheterization, preventing blood from gathering in the appendage.
Our interventional cardiologists use percutaneous techniques to treat a wide range of congenital heart defects. Through catheterization, a "plug" can be fed through a thin tube and inserted in the heart to block any leaks or close holes for patients with atrial septal defects, patent foramen ovales and ventricular septal defects.
