Angioplasty with Stenting
Also called percutaneous coronary intervention (PCI). If coronary artery blockages are detected during cardiac catheterization, an interventional cardiologist can treat these blockages using balloon therapy and stents. The cardiologist inflates a small balloon at the tip of the catheter to open the narrowed artery. A small, cylindrical mesh tube called a stent is placed in the artery to keep it open. Some stents are coated with a drug that is released slowly to prevent further narrowing of the artery.
In a procedure similar to angioplasty, balloons and stents are used to repair or open carotid arteries leading to the brain, lowering stroke risk.
In some people, a small device that shaves the plaque in the coronary artery may be used to open a blockage. This procedure is performed during cardiac catheterization.
People who are not candidates for conventional aortic or mitral valve surgery for stenosis or blockage may be offered this less invasive procedure. A balloon is threaded through a catheter to your narrowed heart valve. The balloon is then inflated to open the narrowed valve.
Mitral Valve Clip
People with mitral valve regurgitation (leaking valve) who are not candidates for conventional valve surgery may be treated with a catheter-based therapy in which small clips are placed on the widened mitral valve to narrow the opening.
Endovascular Stent Graft
People with a ballooning or enlargement of blood vessels -- also called an aneurysm -- may be candidates for a catheter-based approach called an endovascular stent graft. This procedure involves strategically placing a fabric tube supported by metal mesh to reinforce the weakened or enlarged blood vessel, often the aorta.
Congenital Heart Defect Repair
Depending on the type and location of the defect, catheter-based therapies using either balloons to open narrowed vessels or valves, or closure devices to seal abnormal openings, may be performed in place of conventional open procedures.
Stem Cell Therapy
During this experimental therapy, stem cells are injected into the heart muscle. Studies suggest this procedure may improve the heart’s ability to pump blood when severe heart failure has been diagnosed.
This experimental procedure is being tested to determine its effectiveness in lowering blood pressure in people who take multiple medications and have been diagnosed with resistant hypertension. A catheter accesses the renal arteries, then a pulse of radiofrequency energy is delivered to deaden nerves that can be a main cause of hypertension when they become overactive.
