Interventional Cardiology

Interventional Cardiology

Interventional cardiology is a specialty that diagnoses and treats heart and blood vessel conditions using small tubes called catheters. Cardiologists use these small tubes, which they put through your blood vessels, allows providers to avoid doing open-heart surgery. Yet they achieve results that can be lifesaving, like when treating a heart attack.

What is interventional cardiology?

Interventional cardiology uses catheters to diagnose and treat heart disease. Catheters are very small tubes (similar to IVs) that healthcare providers put through your blood vessels. This is why you don’t need an incision for a procedure that uses a catheter.

Interventional cardiologists help people with vascular (blood vessel) and coronary (heart) diseases. These diseases include heart valve defects and septal defects — abnormalities in the walls separating your heart chambers.

Interventional cardiology procedures are performed in a cardiac catheterization lab. Saint Alphonsus has cath labs at both Saint Alphonsus Regional Medical Center in Boise and Saint Alphonsus Medical Center in Nampa.

Interventional cardiology conditions:

  • Aneurysm
  • Atherosclerosis
  • Aortic valve stenosis
  • Atrial septal defect
  • Carotid artery disease
  • Chronic venous disease
  • Coronary artery disease
  • Coronary artery fistula
  • Heart attack
  • Heart valve disease
  • Hypertrophic cardiomyopathy
  • Thromboembolic disease (blood clots)

Interventional cardiology procedures include:

  • Cardiac catheterization
  • Angiogram
  • Angioplasty
  • Coronary atherectomy
  • Fractional flow reserve
  • Intravascular ultrasound
  • Optical coherence tomography
  • Stent placement
  • Heart valve placement and repair
  • Left atrial appendage closure
  • Atrial septal defect closure
  • Patent foramen ovale closure (PFO)
  • Thrombolysis

Additionally, there are specialized interventional cardiologists who treat structural heart conditions as well as interventional cardiologists who offer complex high-risk procedures for certain heart conditions.
