Interventional cardiology procedures deal specifically with treatment of cardiovascular heart diseases. They involve catheterization and are performed by an Interventional Cardiologist in the Cardiac Catheterization Lab.

The most common Interventional Cardiology procedures performed at Atrium are described below.
With a balloon angioplasty, a tiny balloon is used to open a narrow or totally blocked blood vessel. Balloon angioplasty is often followed by placement of a coronary artery stent.
A coronary stent is a small, wire mesh tube implanted in a diseased coronary artery to hold it open. The stent is inserted during cardiac catheterization, usually after a balloon angioplasty has been performed.
Peripheral stenting involves a similar procedure to coronary stenting, but it is used to widen blood vessels other than coronary arteries—most commonly the leg arteries.
Electrical Device Implants
Coronary intervention focuses on the “plumbing” of the arteries and veins, while electrical device implants are focused on the “wiring” of the heart. Devices like pacemakers are used as treatment for coronary patients who have electrical deficiencies in their hearts.

Pacemakers help maintain a normal heart rhythm, usually when a patient’s heart rate is too slow. Pacemaker procedures are performed in the Cardiac Catheterization Lab. The Cardiologist/Surgeon places an electrode next to the heart wall. Small electric charges from a battery travel through the wire to the heart, helping the heart beat in a regular rhythm.
Implantable Cardiac Defibrillator (ICD)
An ICD is a device with leads that are implanted via blood vessels to the inside or surface of the heart. These leads are used to deliver electrical shocks to the heart if needed, as well as to sense the cardiac rhythm or even to pace the heart if necessary. The leads are powered by a pulse generator, usually implanted beneath the skin of the chest or abdomen.
