What is Interventional Cardiology?
Interventional cardiology uses nonsurgical catheter-based (small tubes
inserted into the arteries and guided to the heart) treatment techniques
to manage or reduce coronary artery blockages, stop heart attacks, correct
valvular heart disease, and treat peripheral vascular and aortic vascular problems.
Interventional cardiology procedures are generally less invasive than traditional
surgery. In most cases, these procedures require only one small incision
for insertion of the catheter. Most interventional cardiology patients
do not require general anesthesia and some procedures can take as few
as 30 minutes to perform.
In many cases, patients go home the same day or are hospitalized for only
one night following interventional cardiology procedures, instead of the
longer hospital stay required by other types of surgery. Recovery time
often is shorter as well and symptoms, such as shortness of breath and
chest pain, are usually relieved quickly and effectively.
Key Interventional Cardiology Procedures
Diagnostic and Interventional Cardiac Catheterization
Cardiac catheterization is used to determine and diagnose the severity
and extent of cardiovascular problems, including coronary arteries.
Angioplasty and Percutaneous Coronary Stenting
Angioplasty and percutaneous coronary stenting are procedures to widen
or hold open narrowed or blocked arteries.
Coronary atherectomy is used to remove or reduce large plaque deposits
from coronary arteries.
Balloon valvuloplasty, also called percutaneous balloon valvuloplasty,
is a procedure used to enlarge a narrowed, or stenotic, heart valve.
Coronary Artery Bypass Graft
Coronary Artery Bypass Graft is a surgical procedure to clear blockages
or Chronic Total Occlusion in the arteries through innovative percutaneous
(performed through a needle stick through the skin) techniques.
Coronary thrombectomy is a minimally invasive procedure performed to remove
a blood clot, from a coronary artery or other blood vessel.
Innovated Interventional Cardiac Procedures
Percutaneous Coronary Intervention (PCI)
Percutaneous Coronary Intervention (PCI), also know as Angioplasty, is
a procedure used to open blocked coronary arteries (caused by
coronary artery disease) and restore blood flow to the heart muscle without open-heart surgery.
During PCI prodcure, a special catheter (a long, thin, hollow tube) is
inserted into a blood vessel and guided to the blocked coronary artery.
The catheter has a tiny balloon at its tip. Once the catheter is in place,
the balloon is inflated at the narrowed area of the coronary artery. This
presses the fatty tissue against the sides of the artery making more room
for blood flow.
The use of fluoroscopy (a special type of X-ray that's like an X-ray
"movie") helps the doctor find the blockages in the coronary
arteries as a contrast dye moves through the arteries.
The doctor may determine that another type of procedure is necessary. This
may include the use of atherectomy (removal of plaque) at the site of
the narrowing of the artery. In atherectomy, there may be tiny blades
on a balloon or a rotating tip at the end of the catheter. When the catheter
reaches the narrowed spot in the artery, the plaque is broken up or cut
away to open the artery.
Currently under the leadership of
Dr. R. Michael Wyman, Torrance Memorial is one of three sites in the United States currently
testing and developing this interventional cathterization procedure.
Transcatheter Aortic Valve Replacement (TAVR)
TAVR is the name for a new procedure in cardiology and cardiac surgery
that enables patients with a condition called severe aortic stenosis (narrowing
of the aortic heart valve opening) to receive a new heart valve without
undergoing open-heart surgery. Traditionally, the primary treatment for
aortic stenosis has been surgery. However, certain patients with severe
stenosis were considered too sick for surgery.
As a result of a pivotal new Partner Trial, the FDA has approved the use
of the Edwards' Transcatheter Heart Valve, which utilizes a minimally
invasive procedure to implant a new valve using a method very similar
to the implantation of a stent. Therefore, patients whose conditions were
previously thought to be untreatable can now receive a new valve without
open heart surgery.
