Interventional Cardiology Program

Not all heart conditions can be managed by managing risk factors through medication, diet, and exercise. Interventional cardiology uses a variety of minimally invasive procedures to test for and treat cardiac conditions like coronary artery disease, congenital heart disease, heart valve disease, and peripheral artery disease.

Under the direction of Dr. Adhir Shroff, the Interventional Cardiology Program at UI Health is team of experts in electrophysiology, heart failure, cardiovascular anesthesiology, radiology, endovascular surgery, cardiac surgery, and vascular surgery that works together to provide the best care and most successful outcomes to patients from around Chicagoland.


Our interventional cardiologists possess extensive expertise in a comprehensive range of both standard-of-care and leading-edge procedures, including:

Angioplasty and Stenting

Angioplasty — also known as percutaneous coronary intervention (PCI) — is performed to restore blood flow for patients who have had or are at risk of having a heart attack due to a blockage in an artery of the heart or those with chest pain, shortness of breath, or other symptoms that indicate reduced blood flow in a coronary artery.

During angioplasty, an interventional cardiologist:

  • Sends a catheter through the arteries to the site of a blockage
  • Passes a balloon over a wire inside the catheter and inflates it to push plaque against the vessel wall
  • Deflates and removes the balloon

Angioplasty alone is rarely enough to prevent re-narrowing of the vessel, so interventional cardiologists typically use a catheter to place a mesh tube called a stent in the vessel to hold it open and allow blood to flow.

At UI Health, interventional cardiologists perform more than 90 percent of angioplasty and stenting procedures by placing a catheter through the radial artery in the wrist via a small hole in the skin. Compared with using the femoral artery in the groin, another common entry point, the radial approach allows patients to sit up immediately after the procedure rather than have to lie still for hours, and it significantly decreases the risk of bleeding.

Our interventional cardiologists use angioplasty and/or stenting to treat less common conditions of the coronary arteries, including:

  • Blockages in the left main coronary artery (LMCA): A critical pathway for blood in the heart, the LMCA can narrow as plaque accumulates over time. Coronary artery bypass grafting (CABG), a type of open-heart surgery, is one way to restore blood flow. Certain patients, however, are candidates for a nonsurgical alternative to CABG, in which an interventional cardiologist performs PCI, typically through the wrist, to place one or more stents in the left main coronary artery.
  • Chronic total occlusion: Certain patients may develop complete rather than partial blockages in the coronary arteries that force the body to develop new vessels to reroute the flow of blood. Those vessels are poor substitutes for an artery, so UI Health has developed a program to treat complete arterial blockages, also known as chronic total occlusions. Interventional cardiologists use several sophisticated methods to reopen totally blocked arteries, including antegrade dissection re-entry. With this specialized angioplasty technique, an interventional cardiologist guides a wire past the blockage, inflates a balloon to open the artery from the rear, and sends a stent into the vessel to keep it open.   

Our interventional cardiologists also use angioplasty and stenting to treat blockages in the peripheral arteries, especially those in the legs, where reduced blood flow can cause pain when walking.


A through-the-skin procedure, atherectomy may precede angioplasty and stenting when patients have a lot of calcium in the arteries. The goal of atherectomy is to soften or dislodge the calcium to make it easier to insert a balloon in the artery and allow stents to fully expand. UI Health offers three kinds of coronary atherectomy:

  • Rotational atherectomy: This procedure uses a diamond-tipped, drill-like instrument to bore into the calcium and soften it.
  • Orbital atherectomy This also uses a diamond-tipped, drill-like device to cut into calcium in a circular pattern.
  • Laser atherectomy:  This type of atherectomy uses a laser to soften and clear out calcium, and it is especially effective for treating calcium buildup in patients who already have stents and have experienced re-narrowing of the arteries.

Coronary Artery Bypass Grafting (CABG)

This form of open-heart surgery is appropriate for people who have severe coronary artery disease or who are not candidates for angioplasty and stenting. While a heart-lung machine keeps blood moving through the patient’s body, a surgeon reroutes blood flow around the blocked arteries by creating new pathways using blood vessels taken from the patient’s chest or legs. UI Health surgeons perform many CABG operations each year and have an excellent safety record
