Cardiology Intervention Services

CHOI website Hillcrest Cngtl Hrt 20130117.Jpg Our board-certified cardiologists specialize in a number of interventional services to diagnose and treat heart and vascular conditions in both adult and pediatric patients.

Cardioversion 

A treatment for rapid or irregular heart rhythm. A small electric shock is given to the heart muscle in attempt to restore normal rhythm. This is done under sedation.

Catheter Ablation 

A procedure that uses small wires threaded to the heart to eliminate part of an abnormal electrical pathway in the heart that is causing an abnormal heart rhythm.

Coronary Angioplasty

This procedure widens narrowed arteries. A catheter with a deflated balloon on its tip is passed into the narrowed artery. The balloon is inflated and the narrowed artery is widened.

Coronary Stent Placement 

A procedure used to help keep narrowed arteries open. A small wire mesh tube is placed in an artery to form a rigid support and to hold the artery open after angioplasty. The stent becomes a permanent part of the artery and does not move after it is in place. Sometimes these stents have medicine coatings that help with proper healing.

Directional Coronary Atherectomy

Removes the plaque causing a narrowing in the coronary artery, which decreases blood flow to the heart muscle. A special catheter is used to shave and remove the plaque in a coronary artery. Sometimes used prior to stent placement.

Doppler Flow Wire

A special wire capable of measuring blood flow is threaded into the coronary artery to see how well the artery supplies the heart muscle with needed blood. This is sometimes used during cardiac catheterization to see if a blockage is significant and requires an intervention.

Impella Heart Pump

Patients with certain critical blockages or a weak heart muscle may require additional support like the Impella during a procedure. Without support, they may not be able to safely undergo such high-risk procedures. The Impella is also used in patients experiencing a heart attack and shock. In these situations, the device can provide additional support to the heart and help it rest and heal.

Implantable Cardiac Defibrillator

A device consisting of a battery and wires is placed inside the chest to monitor the heart and treat serious abnormal rhythms. It may treat the abnormal rhythm in several different ways, depending on how the cardiologist programs it. It may deliver electrical impulses to stimulate or pace the heart, or it may deliver a sudden burst of energy to shock the heart out of an abnormal rhythm.

Intra-Aortic Balloon Insertion

A catheter with a large balloon on the end is inserted in the groin and guided into the aorta - the main artery of the body. It is used to support the heart and provide extra blood supply to the coronary arteries. This is typically used in patients with large heart attacks or severe heart failure in the setting of a critical care unit or catheterization lab.

Pacemaker 

An implanted device used to stimulate the heartbeat, preventing slow heart rhythms. It consists of a battery and wires. The wires are placed inside the heart and connected to a generator placed under the skin in the upper chest.

Pericardiocentesis

A small needle is inserted under local anesthesia into the sac around the heart muscle to drain fluid that is causing symptoms. The fluid is often sent for testing to help with diagnosis and treatment. Sometimes an ultrasound is used to help with proper needle placement.

Percutaneous Transluminal Angioplasty

This refers to any procedure involving restoring normal blood flow to narrowed arteries in the arms and legs. A catheter - a small hollow tube - is threaded through a blood vessel to the narrowed artery. A balloon is used to open the blockage and often to place a stent - a small wire mesh - to keep it open and heal properly. The major arteries to the arms called the subclavian arteries and the major arteries to the legs called the iliacs are the usual targets although smaller vessels further downstream can also benefit from this technique.

Renal Artery Stenting

The blood vessels that supply the kidneys are called renal arteries. These may develop blockages leading to problems with hypertension and occasionally kidney failure. A wire mesh called a stent can be placed across a blockage to restore normal blood flow, using techniques similar to how we open the arteries that feed the heart.

Learn More

Rotational Coronary Atherectomy 

A procedure to open narrowed arteries. A rotablade is a high-speed spinning device that removes the plaque blocking an artery in order to improve blood supply to the heart muscle. This is often used prior to stent placement.

Transluminal Extraction Catheterization

A catheter is inserted through a blood vessel in the groin and guided to the heart. The catheter is placed inside a coronary artery that has a blood clot. The catheter then removes or extracts the blood clot.

Temporary Wire Placement

A small wire is placed through a vein into the heart to stimulate a heart that is beating too slowly. The wire acts as a backup until a permanent pacemaker can be placed or until the heart heals and paces normally by itself.
