Interventional Cardiology

Expert cardiologists at the PeaceHealth St. Joseph Cardiovascular Center provide a full range of the most advanced interventional cardiology. 

Coronary Angioplasty

Angioplasty is the opening of heart blood vessels that have become narrowed by plaques. Among them is:
  • Balloon dilation: A very small balloon is used to expand a narrowed artery. 
  • Mechanical stripping of the interior of the blood vessel.
  • Injection of materials designed to dissolve blood clots.

Stents are small wire tubes that ensure arteries remain open after an angioplasty is performed.

We use the latest in stent technology, including drug-eluting stents to decrease the chances of an artery reclogging. A drug-eluting stent is just like a traditional stent, except it is coated with an antibiotic and anti-inflammatory substance that helps prevent re-clogging. Drug-eluting stents reduce the instances and need for more interventions or procedures such as bypass surgery.

FilterWire EX Embolic Protection System

FilterWire treats saphenous vein graft disease (SVG). SVG happens when the saphenous vein from the leg used in coronary artery bypass surgery develops atherosclerosis (a buildup of plaque that clogs the vein). The FilterWire System is designed to reduce complications during angioplasty and stent procedures in those with SVG by capturing the plaque that becomes dislodged during these procedures that might otherwise cause a heart attack.

Chronic Total Occlusion

A chronic total occlusion (CTO) is an artery that has been completely occluded (blocked) for more than 30 days. Currently, there are three methods for treatment of CTOs:

  • Percutaneous intervention: The minimally invasive use of a conventional guidewire technique to slowly push through the blockage and insert a stent to maintain arterial flow. 
  • Coronary artery bypass surgery (CABG)
  • Medical management, including nitrates, calcium and beta blockers. 

Transcatheter Aortic Valve Replacement (TAVR)

Transcatheter Aortic Valve Replacement (TAVR, also known as TAVI) is a minimally invasive procedure for select patients who have been diagnosed with severe symptomatic aortic stenosis and are not candidates for open heart surgery. A TAVR procedure replaces the aortic valve without open-heart surgery.  The procedure is performed by an interventional cardiologist to treat aortic valve stenosis.

In February 2021, the Cardiovascular Center was certified by the American College of Cardiology (ACC) for its demonstrated expertise and commitment to treating patients with moderate to severe heart valve disease with transcatheter valve implantation (TAVI/TAVR) procedures. It is the first health care provider in Washington state and among fewer than 30 in the nation to receive this esteemed distinction.

Transradial Access

Transradial access uses the radial artery, found in the wrist, as an entry point for diagnostic and interventional cardiac procedures. While the primary method for gaining access to the arteries in the United States is through the femoral artery, found in the groin, transradial access has been shown to offer a number of benefits, including reduced site bleeding, a more efficient procedure and quicker recovery.
